IN BRIEF #3-2018

New Siemens E-series gas engine.

Siemens has launched its new E-series gas engine  with a power output of 2MW. The new SGE-86EM gas engine is based on the thermodynamic Miller cycle combustion technology that ensures high reliability, minimal emissions, and longer run times between service intervals. With a mechanical efficiency of about 47 percent and an electrical efficiency of 45.4 percent,

the engine offers a high level of performance for both prime power generation and cogeneration applications. The new engine series’ capacity to deliver on-site power, heat, and cooling translates into an excellent cost-performance ratio.

The new concept of control system development on the base of interactive network.

The article presents a new approach to automation in industry, which allows to increase reliability, to provide almost 100 % factory readiness and to shorten the commissioning time of facilities. The specialists of Sistema-Service Research and Production Company developed new approach

to automatization of gas pumping units on the base of 30 years’ experience. This approach is based on the using of the units of interactive networks. At present Sistema-Service started mass production of units of interactive networks. In cooperation with engineers from leading Russian machine building enterprises the projects for automatization of various gas pumping units were developed. Among the units are GPA-32 Ladoga, GPA-25, GTA-6/8 RM, GTA-25, GTA 2500 and others. Innovative concept will be presented on the booth of Sistema-Service during MIOGE-2018 (Moscow, June 18-21).

MWM biogas power station on the site of agricultural enterprise in Loeberitz.

Five years ago, the cooperative and its partners invested some euro 3 million in a biogas plant with a container cogeneration plant and silo facility at the Loeberitz site. The biogas plant has an electrical output of 600 kW and is operated using farm slurry, farmyard manure and plant-derived biomass material in the form of maize silage. The cogeneration plant has an MWM TCG 2016 V12 gas genset which has been managed and serviced by the MWM Service Centre in Erfurt (Germany) since it was installed five years ago and the availability of the plant at around 8,200 operating hours per year is particularly high.The waste heat generated in the CHP plant is used for heating the adjacent pig-fattening operation, while some of it can also be used for drying cereals as and when required. Since it was commissioned in 2011, the biogas plant has also served as a test plant for trialing the process technology used in MWM engines. Specialists fromMannheim (Germany) come here to test new materials and components and take measurements. The biogas farm also benefits from this since the catalytic converter which is fitted to the plant.

Russian world-class gas turbine units.

REP Holding has mastered the production of the most technological and high-tech parts and components of MS5002E GTU which is part of the new generation gas-pumping unit «Ladoga-32». As part of the localization program, which is systematically implemented at the Holding facilities, the prototype of the rotor of the high pressure turbine axial compressor and the whole set of compressor blades have been manufactured. Manufacture of turbine blades and the combustion chamber elements is at the final stage. Also, within the frames of this project REP Holding specialists have independently developed and manufactured a set of GTU bearings, using Russian materials grades, which will make it possible to avoid using the foreign manufactured analogues.

The project has been implemented in close cooperation with domestic enterprises within record-short time. In February 2017, REP Holding mastered the production of the high-tech components of the gas turbine actually within 1 year. To complete the project, more than 20 collaborators, Russian industrial companies, were involved.

Wаrtsilа 31SG – the world's most efficient 4-stroke engine.

Wärtsilä developed new Wärtsilä 31 engine available in diesel, dual-fuel and pure gas variants. The last of these is the spark-ignited Wärtsilä 31SG, the 20-cylinder version which produces 12 MW of power. When the first Wärtsilä 20V31SG rolled off the production lines this year, it became the world's most efficient simple-cycle internal combustion engine ever built. The Wärtsilä 31SG's defining feature is its ability to reach efficiencies surpassing 50 percent – a milestone within the industry.

Siemens is localizing the production of 118 MW gas turbine in Russia.

Siemens gas turbine technologies Ltd. presents new product to domestic market – H-100 gas turbine rated at 118 MW. It is manufactured under the license of Mitsubishi Hitachi Power Systems (MHPS). H-100 gas turbine has successful operation experience on the site of power stations in Japan. License agreement was signed by Siemens gas turbine technologies and MHPS in March 2017.

The agreement provides for the transfer of rights to Russian enterprise for manufacture, sales, assembling, commissioning and maintenance of H-100 gas turbine. New gas turbines will be used for the construction of power stations in Russian Federation, Armenia, Georgia, Tadzhikistan, Kyrgyzstan, Moldavia.

 New generation power station for green-house complex in Sverdlovskaya Region.

Green-house complex of UGMK-Agro Ltd. is equipped with new power supply system developed on the base of GE Jenbacher gas engines. Main power equipment for the station was supplied by GreenTech Energy. The development of the project and construction of the station was carried out by FITO company. The first stage of the station was commissioned at the end of 2017. Electric output of the station is 26.4 MW,

thermal output is 24.52 MW. It was developed on the base of six GE Jenbacher JMS 624GS-Н01 gas engine plants each rated at 4401 kW with thermal output of 4087 kW. Total efficiency of the station is 91.2 %. Second stage of the station consists of four GE Jenbacher JMS 624GS-NL gas engine plants. At present third stage of the station is under development.

Energas fuel gas treatment equipment for power stations on the sites of gas fields.

Captive power plants on the sites of gas fields create the basis for the development of oil & gas industry, increase power efficiency, profitability and ecological compatibility of hydrocarbon extraction. Energas projects are realized on the sites of various enterprises in various branches of industry. The company gas treatment and gas supply systems developed on the base of booster compressor stations and unit gas conditioning stations confirmed their flexibility, reliability and efficiency during multi-year operation of generating and gas transportation equipment. Complex of engineering solutions is realized under individual projects on the sites of high-power stations, distributed power generation objects, gas turbine test rigs, etc.

HHM 12MV390 – heading the new Hudongmedium speed engine family.

In 2011, HHM decided to update the former E390VA medium speed engine family together with support from FEV.The focus for the development program of this new generation engine family was on market requirements, advancedperformance, fulfillment of latest and future emission legislations and high reliability.

The family with a bore of 390 mm and a stroke of 550 mm covers a power range from approximately 5 MW with aninline 6 engine and up to approximately 17 MW with a V20 version.

The engine’s target applications are marinepropulsion (river and coastal shipping) as well as genset use, meeting IMO Tier 2 NOx emission targets, and alsoIMO Tier 3 standards with an additional exhaust gas aftertreatment system.

Liquid-phase treatment of associated petroleum gas on the base of GazEcos technology.

Using of associated petroleum gas on the sites of the fields, as fuel for gas engines as well, is obstructed or even impossible because of sulphur content. At present different technologies for industrial gases treatment are applied. The most effective technology is gas liquid-phase treatment with chelate complex of iron. This technology

is well-known and described in many sources. GazEcos specialists began to explore the technology in 2014. The main feature here is simplicity of the technology, low self-consumption of power, low cost price of 1 cubic meter of gas treatment. GazEcos associated petroleum gas treatment plant has three of four stages. In result the plant capability for contaminants absorption is significantly increased. Furthermore, the cost of chemical solution is rather low.
