Turbomachinery International recently visited Elliott Group for a tour of its facilities. The big takeaways were the fact that the company does more business in service than it does in manufacturing (p. 36), and the degree of customization required in its products. This approach appears to be working as it has expanded from 1,700 workers in 2007 to 2,700 today. “We don’t tell people what they need to buy based on a pre-set product line,” said retiring Chief Operating Officer (COO) Art Titus. “We build what they need and in downstream oil and gas, that is typically very specific.”

He explained that the company’s singular purpose is the design, manufacture and service of turbomachinery. It accomplishes this via its Jeannette, PA campus as well as a sister site in Sodegaura, Japan with parallel manufacturing, machining and testing capabilities, and a network of service and sales centers around the globe. The company also manufactures its single-stage YR steam turbines (ST) in China in a joint venture with Ebara Great Pump, and has a lubrication and gas seal system manufacturing plant near Jeannette.

Elliott’s core strength is its ability to design and build horizontally and vertically split centrifugal compressors (up to 100,000 HP). They are available in multiple frame sizes with plenty of overlap in between.

“For the downstream oil & gas market, we have to design a machine against very exacting process parameters such as pressure, temperature and flow rate so no two machines are ever exactly the same,” said John Rann, Vice President of Engineered Products. Side stream mixing is a particular area of expertise for Elliott’s compressor engineers. Refrigeration applications often require the addition of multiple large volume side streams to the primary flow. Optimal compressor performance requires accurate fluid dynamic design to merge the streams for minimum pressure loss and maximum efficiency.

Key markets

This expertise serves Elliott well in key markets such as petrochemicals and LNG. The company estimates that about half the ethylene plants in the world use its turbomachinery. With the recent rise in “on purpose” propylene production, Elliott has also been successful in designing large, high flow compressors for propane dehydrogenation (PDH).

Elliott’s strength in LNG is highlighted by the following credentials: It developed the first ever baseload LNG plant and the first GT-driven plant; the first large-scale LNG plant; the first singlemixed refrigerant design; the first mixed refrigerant process LNG plant; the first large propane refrigeration strings; the first dual-shaft GT driven refrigeration strings; and the first dual-mixed refrigerant trains. Its compressors operate today in LNG plants producing in excess of 70 million tons per year (MTPA).

The company has formed an LNG partnership with The Linde Group. With revenues of 17 billion Euros, Linde has 65,500 employees around the globe. Elliott beat out competition from all major turbomachinery suppliers to gain the agreement with Linde's Engineering Division to cooperate in the small-to-midscale LNG business. The parties have developed a main refrigerant cycle compression technology for Linde’s StarLNG plants ranging from 0.2 MMTPA to 1.3 MMTPA. This enables Linde to increase speed to market.

“With cheap gas available, there is an economic case today for small-scale LNG,” said Titus.

Elliott also supplies compressors and steam turbines for refining applications, such as hydrotreating, alkylation, wet gas, and recycle gas compression. Its compressors are used in upstream applications such as gas lift and gas gathering, gas & oil separation, gas treatment and reinjection.

Many Elliott compressor strings are driven by the company’s steam turbines, which produce up to 135,000 HP. Its single- valve YR model STs provide up to 10,000 HP as mechanical drives. In 1963, Elliott developed the world’s first hot gas expander. Today, its power recovery expanders are used in refineries to produce up to 60,000 HP from the thermal energy in the fluid catalytic cracking (FCC) process. Its machines account for about half the FCC power recovery expanders in the world.

Tri-Sen Systems

John Rann commented on the company’s partnership with Tri-Sen Systems on controls, which was launched in 2012 in a bid to standardize controls for Elliott products and reduce time consumed on controls engineering. Rann said the deal had achieved that goal.

“To use an analogy, in the past we were trying to install the plumbing after the house was built,” he said. “Now our controls conversations begin early, and this has resulted in smoother commissioning and more rapid project completions.”

One final area of the Elliott product portfolio deserves a mention. While other OEMs tend to turn lubrication and seal system work over to external suppliers, Elliott has maintained this function in-house. It offers lubrication, seal, and piping systems for rotating equipment from any OEM via an engineering and manufacturing facility near its Jeannette HQ.

Rann and Director of Operations, Engineered Products, Mike Storms, conducted a tour of a vast campus that encompasses 800,000 square feet under roof and 110 acres. It consists of new and old buildings — the company has operated on this site for over 100 years. There are also extensive on-site training facilities — the company realized that fewer skilled workers have been coming out of the school system. So it embarked upon a program to train its own workforce. This has resulted in about 13 machinists, 30 assemblers, 40 service reps and seven welders recruited and trained in the past two years.

The tour comprised visits to multiple buildings of different purposes. What was evident was heavy investment in technology such as the latest computerized numerical control (CNC) equipment, 5-axis machining and heavy duty cranes. A materials lab moved into a new facility last year, and construction of an R&D lab is underway.

Elliott Group’s Global Service (GS) organization recently demonstrated its capabilities during a turnaround at a Middle Eastern refinery and petrochemical complex. The turnaround involved nearly 200 personnel. Elliott’s scope of work included the overhaul and rerate of 23 machines, as well as associated lube oil systems, to expand production capacity.

The overhaul was planned years in advance, and the GS team spent two months on site prior to the shutdown to coordinate tools, parts, and logistics. A total of 5,638 parts were manufactured in Elliott facilities and shipped to the site for the mix of Elliott and non-Elliott equipment.

The overhaul included a recycle gas compressor, a wet gas compressor train with a steam turbine driver, a GE refrigeration compressor and refinery compressor, a cracked gas train with MCO turbine drivers and an ethylene heat pump compressor.

Changing of the guard

With Art Titus retiring this month as COO, he is being replaced by current Vice President of GS, Mike Lordi. Mike’s position is being taken by Ron Frye. His vacant position of Vice President of Industrial Products will be filled by Scott Wilshire. Long-term CEO Yasuyuki Uruma continues at the helm as CEO of Elliott Group.

MAN-powered plant

A gas-fired CHP plant in Shanghai, China is now operating at SAIC Volkswagen Automotive Company, which includes four sets of MGT 6200 GTs by MAN Diesel & Turbo. Waste heat is used to produce steam for use at the facility. According to the National Energy Administration, the gas supply in China is expected to reach 400 billion cubic metres in 2020, and natural gas will increase to represent 10% of primary energy consumption.

World Economic Forum report

Industry estimates show that non-OECD countries will have to double their investments in electricity by 2040 to keep pace with demand, according to a report from the World Economic Forum, where over 2,500 leaders from business, government, international organizations, civil society, academia, media and the arts met earlier this year.

The report cited an International Energy Agency (IEA) forecast that meeting the electricity demands of consumers and businesses in non-OECD countries will require $13 trillion in investment by 2040. It will outspend OECD markets by a factor of 2-to-1.

“From 2000-2014, non-OECD countries invested on par with OECD countries, about $240 billion annually,” said Roberto Bocca, Head of the Energy Industries of the World Economic Forum. “But given the amount of electricity infrastructure that needs to be built to serve growing demand, fast-growing countries will have to double their investments, but also ensure that these funds are used to develop all parts of the value chain.”

The report analyzed best practices in improving investment attractiveness of the power sector in these regions and outlines recommendations:

  • Develop long-term roadmaps to ensure the right balance between renewable and conventional, centralized and distributed power generation, while remaining as technology neutral as possible
  • Integrate policies across the power value chain to ensure that the upstream fuel supply, generation assets, and transmission and distribution (T&D) develop in parallel
  • Capitalize on the declining technology cost curve, and avoid promoting technologies that will likely remain at high cost due to a lack of scale
  • Structure power markets in ways that recognize the full value and costs of technologies, including carbon pricing
  • Make transparent regulations around public-private partners to ease investors’ concerns about committing long-term capital
  • Put measures in place to reduce risk and decrease the cost of capital, allocating residual risks to the most appropriate market participants
  • Foster the development of universities and research institutes that produce the talent that will innovate, develop and manage the power sector in the decades ahead.

“Fast-growing economies have a great opportunity to define the sustainable energy mix and power market structure they need,” said Ignacio Galán, Chairman and CEO of Iberdrola and current chairman of the Forum’s Energy Utilities community. “This will play an essential part in driving the required scale of investment to clean generation, especially renewable, as well as efficient storage and networks, which is essential in the global energy sector.”

Dehydrogenation unit

Clariant has been awarded a contract by Hengli Petrochemical Refinery Co. for a propane and butane dehydrogenation unit in cooperation with CB&I. The project includes the license and engineering design of the co-processing unit, which is to be built in Dalian, Liaoning Province, China.

The design will be based on CB&I’s Catofin catalytic dehydrogenation technology using Clariant’s Catofin catalyst and Heat Generating Material (HGM) to process feedstock containing 300,000m.t. of propane and 600,000 m.t. of isobutane annually for the joint production of propylene and isobutylene. When completed, it will be the largest singletrain co-processing dehydrogenation unit in the world.

The Catofin process operates at optimum reactor pressure and temperature to maximize conversion of propane and isobutene for a high yield. HGM is a metaloxide material designed to increase selectivity and yield of Catofin units. The material is loaded into the catalyst bed with the catalyst where it undergoes oxidation and reduction during the operating cycle, producing heat and driving the dehydrogenation reaction. This boosts yields, saves energy and cuts emissions.

EthosEnergy contracts

EthosEnergy has been awarded a contract by Indorama Ventures Olefins for overhaul and rerate services on ST and compressor units located at its ethylene cracker plant in Lake Charles, Louisiana. The contract is for engineering upgrades for the compressors, component manufacturing, field and shop services, project management, and warranty and risk mitigation.

In addition, Rockland Capital awarded EthosEnergy a contract to provide its combustion optimization ECOMAX system, at the company’s 225 MW Eagle Point Power Generation facility in Westville, New Jersey. The performance management and automated tuning technology system was successfully installed on two DLN-1 Frame 7EA gas turbines equipped with steam injection and wet compression systems. ECOMAX, working together with the other plant upgrades already in place, allowed Rockland Capital to increase the output of the facility by 20 MW, reduce heat rate, and improve emissions performance.

PSEG to spend $1.6 billion

Public Service Enterprise Group (PSEG) plans to spend $1.6 billion over five years to expand its natural gas and other power plants. Combined cycle power plants (CCPPs) are planned in its 2015-2019 budgets, with one in Maryland, another in New Jersey and possibly a third in Connecticut.

PSEG also has an agreement to shut its 383 MW coal plant in Bridgeport, Connecticut in 2021, the only coal plant in the state. Before doing that, PSEG wants to gain approval to build a new gas plant at the site. The company intends to build the new CCPP with a capacity of around 500 MW in Bridgeport by the summer of 2019. Biomethane refineries WELTEC acquired two biomethane refineries last year. This year it purchased an existing biogas plant in Germany.

The Falkenhagen biogas plant is expected to resume operations near the end of 2016. The plant has five digesters, five post-digesters, five digestate storage units and six combined heat and power (CHP) units. It will generate 3.3 MW of electricity with power being fed into the grid. Exhaust heat is to be used for the digestate drying process.

Waste heat recovery standard

The European Turbine Network’s Exhaust Systems Working Group is finalizing the Waste Heat Recovery Units (WHRU) standard to be submitted to the ISO/TC 192. The main objective is to create an ISO standard on exhaust system designs for gas turbines (GTs) used in oil & Gas applications. The next steps are the validation of the modeling method through a benchmark case on a unit and the review of the Heat Recovery Steam Generator (HRSG) API recommendation to amend it.

The project was initiated by Statoil, Shell and Total in 2009, as operators experienced problems with exhaust systems. The goal was to bring together operators facing similar problems, as well as exhaust system designers and external expertise and support, who could develop a common standard for the design of GT exhaust systems.

AAF, Aarding, Alstom, BIHL, Camfil, Dresser-Rand, GE Oil & Gas, Kanfa-Tec, Mjorud, TOTAL, RWTH, Shell, Statoil, TechPart and Frazer-Nash are working together to finalize the first version.
