In this episode of the TurboTime Podcast, Myth Busters Klaus Burn of Ebara Elliott Energy, and Rainer Kurz of RKSBenergy LLC, discuss root-cause analysis (RCA), including what it is, the philosophy and methodologies behind it, what actions should and should not be taken, and more.

Brun said: “RCA, some folks call it root-cause failure analysis, looks at something that failed: Your machine had a catastrophic failure, or you’re missing performance by a percent or two—something is not as you would expect in a compressor or gas or steam turbine, and you want to figure out what it is. So, you perform an RCA based on certain symptoms. In most cases, RCA starts with a review of the machine’s operation that may have preceded the failure and in some cases a metallurgical investigation, which is one of the best indicators as to what failed. It can indicate it was high-cycle fatigue, sudden overload, corrosion or erosion, for example. Then you figure out what excitation may have caused the high-cycle fatigue or what in your process gas may have caused corrosion or erosion.”

Kurz said: “In a way, this is a bit like a detective story. You find something failed, aka the dead body, and then you gather evidence. One of the key things in root-cause failure analysis is that you not only gather evidence, but you also document it. One of the key problems when these reports are written is you have a failure in 2015, for example, and you conduct an RCA, and the next similar failure isn’t for another 10 years. (These events don’t happen that often.) And if you haven't documented what you did for the first one, you can’t use it as a starting point.”

TurboTime Podcast: Root Cause Analysis with the Myth Busters 

In part two of this episode of the TurboTime Podcast, Klaus Burn of Ebara Elliott Energy, and Rainer Kurz of RKSBenergy LLC, discuss surge and choke on a compressor map. They explain where they occur on the map, what happens to the compressor when they operate in these extremes, and about transient operation of a compressor.

Brun explained surge: “On the left side of the map you have surge, and on the right side is choke, overload, or stonewall. The most basic definition of surge is the compressor head cannot overcome the system-imposed pressure, i.e., pressure on the outside on the suction and discharge, and the compressor is not making enough head to overcome that pressure differential. So instead of the flow moving forward through the compressor, the flow suddenly turns around and goes backward through the machine until that pressure balances again, at which point the machine can overcome that head. Then it starts a process again. And that becomes a circular process—you get into these surge cycles, and it's a fairly complex thing.”

Kurz emphasizes that surge is an interaction between the compressor and the system around it, “meaning the compressor by itself doesn't surge,” he said. “If the system forces the compressor to make more pressure ratio than under whatever conditions the compressor is going to make, then the gas thus what it wanted to do in the first place, which is go from the high pressure to low pressure, meaning it goes backward through the compressor. The tricky part with that is on the compressor map, we show what the compressor does. So, the map by itself and that surge line on the map is essentially something you derive from the compressor performance.”

The Myth Busters, Klaus Brun and Rainer Kurz, talk about surge and choke on a compressor map. 

TurboTime Podcast: Part II: Surge and Choke with the Myth Busters 

In this two-part episode of the TurboTime Podcast, Klaus Burn of Ebara Elliott Energy, and Rainer Kurz of RKSBenergy LLC, discuss compressor maps. The duo explains what compressor maps are, what they are useful for, how they fit into the process, and where head, flow, and efficiency islands fit in.

“In its most basic form, a compressor map is a graphical representation of how a centrifugal compressor behaves,” Brun said. “It's somewhat of an oversimplification because more factors play into it; but overall, it gives an accurate representation of what a compressor does within the system that it operates. A standard compressor map has an X and Y axis. The Y axis has something called head—isentropic or polytropic head. Sometimes you also see pressure ratio or a discharge pressure or a fixed section pressure. On the X axis is flow, and most of the time it’s volumetric flow. Sometimes you see mass flow, but that's not very common. Compressor maps also have a surge line on the left and on the right side of the map you have a choke or stonewall area. And finally, you have efficiency islands, and they correspond to the efficiency of the compressor. Not all compressor maps show them.”

Kurz further described efficiency islands: “Efficiency islands refer to the fact that these maps are three-dimensional, but we can only put them in two dimensions on paper. The three axes you want to display are head, flow, and efficiency. You use the efficiency lines in a very similar way to elevation lines. Also, the coordinates of the map that are directly affected by the compressor aerodynamics are head and flow. You can translate head into pressures or pressure ratios, and you can translate actual flow into mass flow, but ultimately what happens aerodynamically in the compressor is described by head and actual flow.”

The Myth Busters, Klaus Brun and Rainer Kurz, talk about compressor maps—what they are, how they are generated, and what they are useful for.

In this episode of the TurboTime podcast, Klaus Brun and Rainer Kurz talk about turbine degradation. They define terms such as fouling, corrosion, erosion, and rubbing and dig a little bit into what causes degradation, how it can be measured and minimized, and the difference between recoverable and non-recoverable degradation.

Burn explained: “A gas turbine system consists of a compressor, combustor, and one or several turbines, so degradation at its highest level is simply measured by what power output and efficiency to expect under certain operating conditions from a new machine and how much less power and less efficiency do you get after that machine has been running for thousands or tens of thousands of hours. The primary measurement is really on a macro level.”

During this episode, the Myth Busters break down the many terms associated with degradation, what components degrade, how it can be measured and minimized, and more. 

TurboTime Podcast: Turbomachine Degradation with the Myth Busters

In this episode of the TurboTime Podcast, the Myth Busters discusses the role of turbomachinery in energy transport and storage, including how gas turbines maximize energy density. They dive into various forms of energy storage—including batteries, hydrogen, and mechanical and thermal energy—for various energy sources such as wind, solar, fossil fuels, etc., and more.

During the energy transport and conversion processes, for example in the case of hydrogen, there are significant energy losses. The lowest losses are with coal, then oil and fossil fuels. As a result of these losses, “Hydrogen is a viable solution for storage, but it’s not a great solution to power a large-scale electric power plant by itself,” Kurz said.

Really, energy comes down to sustainability, affordability, and sustainability of supply – and in this equation, renewables are typically intermittent and not a reliable full-time source of energy.

So where does turbomachinery fit into all of this?

“From a turbomachinery perspective, if you exclude electric—because as Rainer said, it's not always applicable, as you can’t transport energy from Venezuela to Florida along an electric line—then you have to convert your energy stored material, be it natural gas, oil, coal, or from an alternative source then you have to convert it into hydrogen or ammonia or something else, and then transport it,” Brun explained. “All these convergent processes utilize turbomachinery. We have maybe 100 years of experience transporting oil in pipelines and ships and trucks and that involves a lot of pumping—we're very good at pumping – it’s very efficient. We also have about a similar amount of time compressing natural gas, which over the last 40 - 50 years we've used a lot more centrifugal compressors for transporting natural gas. Now we're running into the challenge of sustainable alternative energies where basically you're saying, ‘OK, I'm going to take my wind and solar electric and convert them to let's say hydrogen or ammonia or dimethyl ether or methanol—there are a lot of fluids that you can make from electricity that are energy carriers—but then they have to be transported. Hydrogen is the lightest gas (We had a previous podcast where we talked about the challenges of 

). Similarly, ammonia is a liquid that has to be transported at slightly refrigerated temperatures, and it brings its own challenges because it's highly poisonous and very corrosive to a lot of materials. Dimethyl ether is not that hard to transport—it’s similar to diesel—but it's very expensive to make. Methanol is also highly poisonous. So there are a lot of other challenges that you now face with these energy carriers that you worry about when transporting your original form of energy to the end user.”

Klaus Brun and Rainer Kurz dial into energy storage and transport—why they are necessary, how turbomachinery fits into these processes, and more.

Myth Busters Klaus Brun and Rainer Kurz join the TurboTime podcast to chat about additive manufacturing. They dive into its history in the industry, its advantages as a viable technology, its limitations, and new advancements that could drive the technology further.

Brun explained: “About 40 years ago, additive manufacturing technology started coming out based on using materials such as polymers and resins that were heated up and layered on top of each other using some kind of robotic arm or plotter that in the 3D space. It wasn’t all that relative from a turbomachinery perspective at the time because yes, you could use that to make a mold for a cast, but other than that, it wasn’t realistic. About 20 years ago, we started seeing additive manufacturing using metals. There are a number of techniques, but the most popular ones are direct metal sintering or selective metal-laser sintering—these techniques are when you have a layer of metal and a heat source, and you put the heat source on the powder-metal layer to create a 3D geometry in 3D space. That technique has developed over the last 20 years—it came out with lots and lots of promises, some of which held up while other promises didn't hold up."

“From a turbomachinery perspective, there are many parts in a compressor, for example, or a gas or steam turbine, that are relatively standard pieces; you would probably not use additive manufacturing for those pieces because they're always the same, so you would cast them or quickly machine them. But then there are certain pieces that are either very intricate in geometry, so they require many smaller pieces to be put together or that are customized like impellers for centrifugal compressors. So here, theoretically, additive manufacturing should have an advantage because additive manufacturing provides you with the potential to build customer parts.” 

What’s the history of additive manufacturing, how is it used to manufacture turbomachines, and does it really have a future in the turbo industry? Find out more from the Myth Busters in this episode of the TurboTime Podcast. 

TurboTime Podcast: Additive Manufacturing with the Myth Busters 

Myth Busters Klaus Brun and Rainer Kurz join the TurboTime podcast to talk about turbomachinery factory and field testing—why are turbomachines tested, what’s standard, what’s extra, are the costs really worth it, uncertainty versus accuracy testing, different types of compressor-performance tests, how to test a gas and a steam turbine, and when is a full-string test necessary?

Brun explained: “When you make a machine of any kind, before delivering it to a customer, you want to make sure it actually functions, so standard tests are performed and then there are additional tests that some customers may require. Complex turbomachines—compressors, gas turbines, steam turbines, and even pumps—require some kind of factory testing to make sure the machine meets the basic functionality, it doesn't fly apart, and it performs at a certain level. From there, it gets a little more complicated, as each machine is different. For example, a gas turbine performance test can be performed in the factory or the field. In the factory, a prescribed test by API 616 could be used.

“A field test is a fundamentally different test where the machine is already installed, commissioned, started up, and sent to some engineers or technicians in the field to test under the conditions that may not necessarily be identical to the conditions that the machine was originally designed for or contractually agreed to or under factory testing conditions, so it's a more challenging test.”

In this episode of the TurboTime podcast, Klaus Brun and Rainer Kurz discuss turbomachinery factory and field testing—what they are good for, cost, and more. 

TurboTime Podcast: Factory and Field Testing with the Myth Busters

In this episode of the TurboTime podcast, the Myth Busters, Klaus Brun, the Director of R&D at Elliott Group, and Rainer Kurz, a recent retiree from Manager of Gas Compressor Engineering at Solar Turbines, discuss turbomachinery codes and standards. The two differentiate codes versus standards, which are important for turbomachinery, and what to do if an operator or manufacturer disagrees with a standard.

Brun broke down the four components: standards, codes, specifications, and guidelines. “A standard is somewhat of a generic requirement; you can almost call it the minimum requirement that industry associations agree on for a piece of equipment,” he said. “There's a lot of gray area between here. Next are specifications—they are often related to a specific customer—one of the major oil companies may have its own specifications, and they often tie in standards. For example, let's say Shell or Chevron has their own machinery specification, and they may refer to standards, such as American Petroleum Institute (API) 616 or the American Society of Mechanical Engineers (ASME) standards, material standards, etc. And then you get into things like codes, where the gray area becomes even bigger. But codes traditionally refer to something a little stricter. These can be test codes, where there is a process that you have to follow, and you don't deviate from this process. There are codes related to OSHA requirements or legal requirements. Codes tend to be a little more rigid, more relevant, and more richly followed. Finally, there are industry guidelines from the API and other professional societies. They give advice and guidance on how to handle testing processes, design, etc.”

Kurz stressed that standards are not legally enforceable unless included in a purchasing agreement: “What makes a standard enforceable is if a customer in the purchase specifications says ‘Thou shalt follow such and such API requirement or these ASME standards.’ And then it becomes part of the contract and enforceable” he said.

Kurz also pointed out that one purpose of codes and standards is for system integration. “If you build a refinery, there's one manufacturer who builds the compressor, then there are people who build the pressure vessels, others who build the piping, and maybe the steam turbines. So, there are a lot of different parties involved that have to come together. And one thing that these codes and standards do is create a reasonable definition of the interfaces. At the end of the day, somebody needs to integrate all that equipment.”

The Myth Busters, Klaus Brun and Rainer Kurz, discuss turbomachinery codes and standards on the TurboTime podcast. 

TurboTime Podcast: Turbomachinery Codes and Standards with Myth Busters

In this episode of the TurboTime podcast, Klaus Brun and Rainer Kurz talk about methane leakage in the oil and gas industry, which is only one of the many sectors that contribute to methane emissions in the United States. The biogas sector, including landfills and agriculture, contributes to methane leakage as do coal mines. That said, our industry still accounts for a percentage of methane emissions. The Myth Busters discuss where and how it occurs in the oil and gas industry, how different types of compressors compare in terms of leakage, the role of dry gas seals, and more.

“Methane leakage, in our industry, is primarily from natural gas; and natural gas is called natural gas because it is natural—it is naturally occurring and naturally created,” Brun said. “So, if you talk about methane leakage in the oil and gas industry—really what we should be talking about is natural gas leakage—it is a relatively small part overall of the total natural gas leakage in the world. It is roughly three times smaller than natural gas that is created by natural sources being wetlands and swamps and whatever. The oil and gas industry contributes about three times less than what natural sources do. Also, agriculture contributes about twice as much natural gas. The actual amount of leakage of natural gas into the environment due to the oil and gas industry is somewhat debated and a lot of numbers are floating around, but typically you're talking somewhere between 10 - 20% of the total natural gas that is emitted into the environment comes from oil and gas. The rest is, as I mentioned before, from natural-occurring sources, such as wetlands and agriculture.

“When you look at the oil and gas process, which basically means you're getting oil and gas out of the ground at a well, and then that oil and gas is transmitted to pipelines, and then it goes to either a consumer, you and me, or it goes to industrial places, or it goes to power plants,” Brun continued. “And so, there are many places in that process where it can leak. For very basic economic reasons, nobody wants this gas to leak, right? It costs a lot of money to get it out of the ground, and it costs a lot of money to transport it, and it costs a lot of money to do something with it. So, nobody really wants it to leak, so there is a natural desire by our industry to keep this gas from leaking, but it does.”

In this episode of the TurboTime podcast, Myth Busters Klaus Brun and Rainer Kurz talk about methane leakage. 

TurboTime Podcast: Methane Leakage with Myth Busters 

In our two-part podcast episode on compressor drivers, the Myth Busters give a detailed account of various drivers, including gas turbines, steam turbines, and electric motors. Klaus Brun and Rainer Kurz talk about the general features of each driver, the advantages and disadvantages of each, and how to match a compressor with a driver when factoring in fuel sources, power, speed, the type of compressor, and other determining factors. They also dive a little into gearboxes and why they are, at times, needed.

“First, we need to look at what is the compressor?” Brun said. “A compressor is used to compress the gas; it is a machine that requires some kind of driver that puts energy into the compressor. So, you need a device that the compressor wants to run at a certain speed and certain power. There has to be some kind of input device that can be divided by application, fuel source, power source, and so on. So, let's say you have a centrifugal compressor—you probably want something that spins, right? An electric motor drive, a gas turbine, a steam turbine …if you're driving a reciprocating compressor, you would like something like an engine that also reciprocates because that tends to match a little better. But you can also use an electric motor.

“Then the question becomes—before you get into the technical stuff—what fuel is available? Let's say you are running a centrifugal compressor on a natural gas pipeline. Then the obvious choice is a device that can burn natural gas as a fuel, and that's typically a gas turbine. Similarly, if you're in a refinery or some kind of petrochemical application where you have a lot of steam available because you have boilers and other processes that require steam, then you would select a steam turbine as your driver. In many cases, because electricity is available or other restrictions keep you from running a gas or steam turbine, you would choose an electric motor drive, which presents advantages and disadvantages. But you have to remember that an electric motor drive does require quite a bit of electric power.”

In this episode of the TurboTime podcast, the Myth Busters break down the types of compressor drivers—their advantages and disadvantages, optimal applications, and more.

Turbo Tour of EthosEnergy’s facility in Houston, Performance Center Director Daniel Tegtmeier offered his insights into the growth and evolution of remote monitoring, its advantages and challenges, and how the company seeks to establish partnerships in all things turbine- and plant-related.

Daniel Tegtmeier of EthosEnergy shares how remote monitoring has grown over the past several years and the advantages and challenges of virtual capabilities. 

Remote Monitoring: Growth, Advantages, and Challenges

Q: How has remote monitoring grown and evolved over the past several years? What’s next?

What started as very manual processes has now evolved to mostly automatic and automatically generated monitoring activities. What used to take operators and engineers days to troubleshoot problems is now an automated process via advancements in technology.

Q: EthosEnergy now has full start/stop capability on natural gas-fired power plants. What advantage does this offer your customers?

It’s more than just start and stop in thermal plants; we can start and stop renewable assets as well. Some of the advantages of remote operation are efficiencies. You could streamline the staffing model for intermittent thermal assets. Secondly, our package includes remote monitoring and advanced analytics that’s applied to the remote operation of customer assets, ensuring that they stay competitive in today’s market.

Q: What’s the biggest challenge facing the power industry as it relates to remote operations?

The biggest challenge is the reluctance to shift operating modes from mostly on-site human presence—operating the plant as designed—to remote facilities that apply humans to asset monitoring.

Q: What are EthosEnergy’s five- to 10-year goals?

The five-year goal is growth. EthosEnergy aspires to be a partner in all things turbine- and plant-related, and it’s not just the power industry. Turbines are used in a host of operations like LNG and oil and gas—we seek to be the largest partner for all those industries in the realm of rotating equipment. We want to increase partnerships and our OEM presence.

 spoke with Dag Calafell, the Advisory Committee Chair of Turbomachinery & Pump Symposia (TPS) and Asia TPS, about the new research consortium and laboratory at Texas A&M. He also talked about the differences between TPS and Asia TPS.

TURBO: Are you excited about any upcoming or underway projects at the Texas A&M Engineering Experiment Station?

You may have heard from Dr. Eric Peterson, the Director of the Turbomachinery Laboratory at Texas A&M, that a whole new laboratory space is being created that will deal more with systems instead of traditional machinery components. The turbomachinery laboratory research has been traditionally on component work, but now we will be looking at systems overall. That facility is scheduled to open at the end of this year. There will be a new research consortium with topics such as carbon capture and greenhouse gas emissions.

TURBO: Do you have plans for the next Asia Turbomachinery & Pump Symposia?

The Asia event is every two years, and we have found there is a difference in focus between TPS and Asia TPS. TPS is a little more practical, more 

—what do we have, what do we do with it, and how do we optimize our facilities? Whereas Asia TPS a broader event where we talk about research, upcoming products, product development, etc. We are seeing Asia TPS develop in that direction, going from case studies on optimizing machinery to what solutions should we be developing for the future and for some of the problems that we have today.

Dag Calafell of TPS talks about the new wing of the Turbomachinery Lab at Texas A&M and its shift in focus to systems versus components and plans for Asia TPS.

spoke with Dag Calafell, Advisory Committee Chair of Turbomachinery & Pump Symposia (TPS) and Asia TPS, about the latest trends in turbomachinery and efforts that he sees across the industry to decarbonize.

TURBO: What trends you’re seeing in turbomachinery?

What we're seeing now is that the traditional turbomachinery topics are still important, but we're looking more at how to integrate the turbomachinery optimization/reliability topics using AI, using machine learning, and how can we be part of a larger system where we're optimizing revenues, profitability, and supply chain logistics.

TURBO: What efforts are you seeing for decarbonization?

 A couple of presentations earlier today addressed decarbonization. One was on integrating gas turbines into bottoming cycles, and another one was a tutorial on using all the various technologies for carbon capture. It talked about how today we're using amines but what are we going to be doing in the future, such as exhaust gas recirculation? So, a lot of our program is indeed how do we minimize our emissions. One of our end users is working on using AI and machine learning algorithms to optimize their turbomachinery trains to run them at peak efficiency and therefore reduce emissions across the entire company.

At TPS 2024, Dag Calafell of TPS, shared turbomachinery trends and industry efforts toward decarbonization.

Turbomachinery International spoke to Klaus Brun, Ph.D., the Director of Research and Development at Ebara Elliott, at Turbomachinery & Pump Symposia (TPS) 2024 in Houston. He shared insight into Elliott Group’s rebranding under Ebara Corp. and how the new entity will tackle industry challenges with an upcoming portfolio of sustainability-focused products.

“Elliott, like any other company in our industry, must follow what our customers do and what our market does. We’ve seen a significant transition in the energy industry over the last 10-15 years. We’ve seen more sustainability and more green energy, and so our products need to change with that market. That doesn’t mean we’re neglecting our current customers or the industry we’ve been serving for over 100 years, but we do have to address the changes we see in the energy industry. Our new name is Ebara Elliott Energy Co., with a specific focus on the energy market and not just on products.”

TURBO: What are the biggest challenges facing the industry?

“Everybody’s talking about decarbonization of the industry, so we’re looking at hydrogen and CO

. These are very new products that need to be developed—they currently don’t exist or are not as optimal as they should be. To meet these drastic market changes, we must develop new products and it’s not just the products, but the entire organization. As our customers change toward decarbonization and sustainability, we must change with them.”

Dr. Eric Petersen, Professor of Mechanical Engineering and Turbomachinery Laboratory Director at Texas A&M, talks about the hottest sessions and topics at the 2024 Turbomachinery & Pump Symposia.

“The hottest technical sessions are the ones that have to do with emerging technologies, for example, those related to supercritical CO

 in terms of sequestration—basically preventing CO

 from going into the atmosphere," Dr. Petersen said. "That’s a big national and international concern, so a lot of engineering companies are working toward compressing, transporting, and handling large quantities of CO

“Other hot topics are our more classic topics. There's a new generation of engineers that want to get up to speed as quickly as possible on the basics of turbomachinery. We do this through our tutorials, short courses, and discussion groups, so there's a lot to learn from the generation of experienced engineers who form our advisory committee. A lot of our presenters are key engineers in the industry who have been working in turbomachinery for over 20 years.”

Turbomachinery International interviewed Tim Allison, Ph.D., the Director of the Machinery Department at Southwest Research Institute (SWRI), at Turbomachinery & Pump Symposia (TPS) 2024 Houston. The director shared what new research projects SWRI is working on and what turbomachinery advancements the institute is most excited about regarding decarbonization.

TURBO: What new research projects is SWRI working on?

 “We have several pretty exciting research projects,” Allison said. “Standing next to this turbine highlights one of our projects in supercritical CO

 turbine that was developed with GE Vernova. We are running the Gen. 2 turbine at the STEP sCO

 Demo Pilot Plant. We've run it this year a couple of times with the completion scheduled for this fall.”

TURBO: In terms of decarbonization, what turbomachinery advancements is SWRI excited about?

 “I’m excited about a couple of other projects that we have. One is using turbomachinery to decarbonize ethylene cracking—we have a project for the DOE with Siemens Energy to prove out a rotating olefin cracker, or a turbo cracker, product they're commercializing. We’ll do a full-scale test of that product. We also have some projects on thermal energy storage for long-duration energy storage for the grid. But I am really excited about the trends that couple thermal storage to turbomachinery systems—think a gas turbine that's fed with thermal storage or integrates the thermal storage for another process.”

"Yes, Valley Forge is most well-known for load-indicating externally threaded fasteners. We take the mystery out of torque-based load indicating and we have direct tension or direct load-indicating fasteners. This year we are launching an industry first compression-based load-indicating fastener. To date, for many years our fasteners have been tension-based load indicating and this year we’re launching a compression-based load-indicating fastener. The application is related to power generation. This is a housing assembly that was installed on the original series of General Electric’s wind turbines. We have a bolt that is placed in the assembly and the bolt is under compression, as opposed to being under tension. We have adapted our load-indicating technology to enable the same SPC-4 configuration we typically utilize, but this time the bolt is in compression instead of tension."
