Caption: First Dresser-Rand LNGo solution in operation
Monetizing stranded gas
Dresser-Rand, part of Siemens Power and Gas, has commissioned its first micro-scale natural gas liquefaction system for Frontier Natural Resources at the Ten Man liquefied natural gas (LNG) facility in Pennsylvania. The modular, portable LNGo technology enables distributed production of LNG for local demand. The unit monetizes stranded gas assets at Tenaska Resources’s Mainesburg field, located in the Marcellus shale play. The standard LNGo system consists of four different modules, each handling one step of the liquefaction process. It can be transported on eight trucks, deployed directly at the gas field and has a footprint of about 508 m2. The Ten Man facility began production in mid-September last year, just four months from contract signing, and has produced some half million liters of LNG since startup. The micro-scale LNGo technology is said to have low capital and operating costs and can be deployed in rough terrain or remote regions, eliminating the need to establish an expensive gas pipeline infrastructure or arrange for long-distance trucking of LNG from centralized plants to point of use. It can function as a decentralized solution where the requisite pipeline infrastructure is lacking, or as an onsite transformation solution to reduce or eliminate flaring of petroleum gas at oil rigs or producing gas fields.
Power plant expansion
Tampa Electric converted four, gas-powered, simple-cycle generators at the Mulberry power plant into a combined-cycle power plant (CCPP) system, adding 450 MW. The $660 million expansion project was designed and managed by Black and Veatch. With the “four-on-one” project, the gas turbines (GTs) will direct their exhaust heat to a single boiler. Its high-pressure steam turns a secondary generator, increasing the maximum output by two-thirds.
University of Notre Dame Turbomachinery Laboratory (NDTL) in South Bend, Indiana, has a 19-month, $2.5 million agreement with Doosan Heavy Industries to conduct compressor research and testing to support the development of a 300 MW-class gas turbine. The compressor test will study aerodynamic phenomena that computers cannot simulate. Testing, design, analysis, fabrication and assembly will occur at NDTL’s 10 MW compressor test cell, which will become fully operational this fall. NDTL’s 28,000-square-foot facility offers experimental and numerical capabilities for the development of rotating machinery that requires high power levels and related specialized support. These capabilities create a shorter development path for new gas turbine technologies. NDTL is currently involved with a variety of collaborators, including Pratt & Whitney, GE and Honeywell.

While workers in the engineering technology (ET) field play an important role in supporting U.S. technical infrastructure and the country’s capacity for innovation, there is little awareness of ET as a field of study or category of employment in the U.S., says a new report from the National Academy of Engineering.
An Engineering Technology degree and Bachelor of Science in Engineering are closely related fields of study with noticeable differences in learning curriculum. Most notably, a Bachelor of Science in Engineering emphasizes theories and advanced concepts while an Engineering Technology degree
emphasizes hands-on application and implementation.
In 2014, there were nearly 94,000 four-year engineering degrees, nearly 18,000 four-year ET degrees, and more than 34,000 two-year ET degrees
awarded in the U.S. Of the roughly 400,000 people employed in ET in
2013, an estimated 80% were working as engineering technicians.
A survey of employers of engineering technicians and technologists found that 30% of nearly 250 respondents had never heard of ET education. In addition, one-third said they did not know the difference between work performed by engineers and work performed by engineering technologists. Within academia, the report suggests that leaders of two-year and four-year ET programs should engage in discussions with leaders in postsecondary
engineering education about the similarities and differences between the two
variants of engineering and how they might complement each other while
serving the interests of a diverse student population. The ET education community should also consider ways to make the field’s value more evident to K-12 teachers, students, and parents, as well as to employers.

Natural gas report
The American Gas Association (AGA) released its 2017 Playbook on the role of natural gas in North American society. “America’s abundance of clean natural gas is driving low prices for homes and businesses which is leading states to find new ways to extend natural gas to more communities,” said AGA President and CEO Dave McCurdy. “Efficient use of this domestic resource can help us achieve our national goals.” The AGA report found that natural gas has led to $76 billion in savings for American businesses since 2009. It also highlighted the fact that New England has a critically constrained natural gas pipeline infrastructure. The average price for natural gas for all users in that area was 27% higher than the national average in 2015.
GE has been awarded contracts for eight Integrated Compressor Line (ICL) units up to 14 MW for OGE (Open Grid Europe) and TAG (Trans Austria Gasleitung) to transport gas across Europe.

Siemens technician working at the company’s manufacturing and service facility in Nuremberg, Germany
Siemens has finished its first full load engine tests for GT blades produced using Additive Manufacturing (AM) technology. The company validated multiple AM printed turbine blades with a conventional blade design at full engine conditions. The components were tested at 13,000 revolutions per minute and temperatures beyond 1,250 °C. Siemens also tested a new blade design with a completely revised and improved internal cooling geometry manufactured using AM technology. The project team used blades manufactured at its 3D printing facility in UK. The blades were installed in a Siemens SGT-400 GT with a capacity of 13 MW. The AM blades are made out of a powder of polycrystalline nickel superalloy, allowing them to endure high pressure, hot temperatures and rotational forces. At full load, each of these turbine blades is travelling at over 1,600 km/h, carries 11 tons, is surrounded by gas at 1,250°C and cooled by air at over 400°C.
Siemens, together with its Japanese consortium partner Marubeni Corporation, has received an order for the delivery of a CCPP to Thailand. Stateowned utility Electricity Generating Authority of Thailand (EGAT) will operate the plant in South Bangkok consisting of two Siemens H-class units in a singleshaft configuration. Commissioning is due in 2019. The power plant with an electrical output of around 1,200 MW will include two SGT5- 8000H GTs, two SGen5-3000W generators and two SST5-5000 STs. Also included are two heat recovery steam generators (HRSGs) by NEM and the SPPA-T3000 control system.
Siemens has received a major order for 12 compressor trains for two onshore natural gas processing plants in Iran. Palayesh Parsian Sepehr will operate the plants. The customer is the EPC Hampa Engineering. Commercial operation is expected end of 2018. The trains each contain a Siemens STC-SV vertical split compressor and will be used in two natural gas processing plants. Four will be driven by Siemens SGT-700 GTs, four by Siemens SGT-100 GTs, and two by an electric motor.
New combined cycle unit

Scheduled to be in operation before 2020, plant capacity will be 550 MW using an SGT5-8000H GT, an SST5-5000 ST, a water-cooled SGen5- 3000W generator manufactured in Germany as well as the SPPA-T3000 control system.
Siemens has won an order from Oil and Natural Gas Corporation (ONGC) in India to overhaul 18 RT48S & RT56 units driven by Industrial AVON and Industrial RB211 gas generators. The turbines are operating at ONGC’s Mumbai High Asset and Neelam & Heera Asset in Mumbai, India.
Siemens has also achieved the first commercial installation of a 3D-printed part in a nuclear power plant. The replacement part produced for the Krško nuclear power plant in Slovenia is a metallic, 108mm diameter impeller for a fire protection pump that is in constant rotating operation. The water pump provides pressure for the fire protection system at the plant. The original impeller was in operation since the plant was commissioned in 1981 but its manufacturer is no longer in business. Obsolete, non-OEM parts are particularly well-suited for 3D printing as their designs are virtually impossible to obtain. Siemens reverse-engineered and created a “digital twin” of the part. The company’s AM facility in Finspång, Sweden, then applied its AM process using a 3D printer to produce the part.
Siemens and its Dresser-Rand business have been contracted to deliver two GTdriven compressor trains and two GT generator packages for the Liwa Plastics Industries Complex, a petrochemical project located in Oman. The natural gas liquids (NGL) extraction plant in Fahud is a part of this industrial complex. It should begin operations in 2019. Siemens will supply four SGT-700 GTs. Two will drive a barrel-type turbocompressor (STC-SV) for lean gas compression. The other two GTs will drive a generator to supply electricity to the plant.
Siemens will supply five F-class GTs to the Fadhili CHP plant in Saudi Arabia. With a generating capacity of 1,200 MW, the plant will supply electricity and process steam to a new natural gas extraction plant. The turbines will be produced at the Siemens Dammam Energy Hub (SDEH), the Middle East’s largest gas turbine manufacturing facility. Siemens’ scope of supply includes five generators and a control system, all of which will be commissioned on site.
Siemens’ Dresser-Rand business has received an order from Air Liquide for a compressor train to be used in an air separation plant in China.
