METHOD OF COMPLEX USE OF ASSOCIATED PETROLEUM GAS Russian patent published in 2013 - IPC E21B43/00 F02C1/02 

FIELD: oil and gas industry.

SUBSTANCE: after start of gas turbine the air and associated petroleum gas is supplied into the turbine. Compressed gas and air are directed into combustion chamber, where combustion takes place. The heat of expanding hot gas forces the working turbine to rotate that rotates compression turbine and rotor of electric generator. Water obtained from the well, where oil is produced, is preliminary cleared from impurities and with the help of pump actuated by gas turbine shaft it is supplied through economiser. Hot air coming from working turbine is supplied to economiser. The water is heated due to hot air. Then water is additionally heated in reheater containing tubular heating element that gets energy from electric generator and supplied through steam separator. In steam separator steam is separated from excessive water. Separated hot water is used for household needs. Steam obtained in separator is additionally heated in superheater and directed to combustion chamber, where simultaneously after compression turbine there supplied is compressed associated petroleum gas mixed with air. Connection pipe with pressure sensor and valve is connected to combustion chamber.

EFFECT: increase of associated petroleum gas use, reduction of environment pollution.
