Utilizing previously wasted gas at a Western Siberian production facility, GE Energy is supplying 12 of its Jenbacher gas engines to support on-site energy production for Russian oil and gas producer Monolit LLC.

At the facility, the previously flared waste gas, or Associated Petroleum Gas (APG), will be separated into liquefied natural gas and other ‘transportable’ products (including propane, butane, and ethane) for the chemical industry. GE’s Jenbacher units will generate more than 15 MWe to support production activities at the Monolit site in Shapinskoe, 150 km south-east of Khanti-Mansiysk in the Western Siberian lowlands.

Monolit, a division of the Roza Mira Group, will use APG to fuel GE’s containerized Jenbacher engines. The project marks the first time GE has installed its special APG-standardized, Type 4 engine version. The units feature a low compression ratio ensuring maximum output with low methane gases, as well as a specific engine management system and remote engine diagnostics to assure high engine availability levels despite varying gas compositions. The modular design of GE’s containerized engines also allows them to be relocated to other sites when APG volume decreases in one area.

By utilizing the APG from nearby drilling fields at Shapinskoe for on-site power generation, Monolit will avoid the need to transport diesel fuel over long distances, thus delivering significant environmental benefits. According to the customer, the utilization of APG for onsite power generation will also save about 536,000 tonnes of carbon dioxide equivalents per year at the gas processing facility and gas engine plant.
A new national law requiring producers to utilize 95% of their APG is scheduled to go into effect on January 1, 2012.

Monolit’s gas engine order was arranged by Max Motors, one of GE’s authorized distributors for Jenbacher gas engines in Russia. The project’s units are scheduled to be installed during the summer of 2009. Commercial operation is expected to begin in the third quarter 2009.
