Associated gas utilization
More than 20 billion cubic meters of associated gas are flared in Russia every year and that leads up to 400 tons of atmospheric emissions. Through the utilization of such a volume of associated gas over 10 billion dollars of income might be obtained.
In order to prevent the air pollution caused by noxious emissions and to reduce the greenhouse gas emissions generated by associated gas flaring, in 2009 Russian government fixed the associated gas flaring target for 2012 and the subsequent years at the rate of no more than 5% of the produced gas. The pollutant emissions charge within the target was 4,5 times increased, and in case of the target falldown - 22,5 times increased.
Taking into account that the level of associated gas utilization in Russia is at the average of ~ 73% this governmental regulation provides favorable conditions for gas-turbine technologies promotion, whereas the usage of associated gas for power generation permits to solve simultaneously and effectively energy and environmental problems and heat supply needs as well.
That is why Perm enginebuilders - designers and manufacturers of modern, highly efficient gas-turbines (GTU) and gas-turbine gensets (GTES) on the base of aircraft technologies - are consecutively working on generation of gas-turbine and gas-turbine genset versions running on associated gas.
The long-term operation of these units is indicative of the great environmental and economic effect of Perm gas-turbines and gas-turbine gensets application.
For example, only one gas turbine genset with GTU-4P gas-turbine at "Konitlorsky" production field, running on associated gas, reduces atmospheric emissions of polluting substances by 120 thousand tons per year, including greenhouse gases (methane, carbon dioxide) - by 107,7 thousand tons. In addition, the genset is located in immediate proximity to oil extraction area and that eliminates the need for construction of gas-collecting units.
In Surgutneftegaz-company gas turbine gensets with perm GTU-12PG-2 gas-turbines running on associated gas are widely operated.
Two GTES-24 and GTES-36 gensets with GTU-12PG-2 gas-turbines with total power rated at 60 MW at Russkinsky and Bittemsky oil and gas fields permit to utilize 500 million cubic meters of associated gas that used to be flared earlier and polluted the atmosphere. Associated gas utilization allows solving an important problem of West-Siberian region ecology.
Among Perm enginebuilders' units, running on associated gas, there is the first Russian "Ural-6000" gas turbine pumping unit.
