METHOD OF PREPARATION OF FUEL GAS Russian patent published in 2016 - IPC F25J3/08 C10G5/06 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to a method of fuel gas preparation for gas-turbine power plants and can be used in oil and gas industry and power engineering. Method comprises compressing, cooling, and gas separation. Gas before compression is subjected to absorption of circulating absorbent high pressure to produce absorbent low pressure, mixed with balance absorbent high-pressure compressed obtained compressate cooled and separated with production of condensate and compressed gas, which is subjected to absorption of cooled absorbent low pressure to produce fuel gas and high-pressure absorbent, separated into circulating and balance.

EFFECT: reduced losses of hydrocarbons C₅₊ with fuel gas.
