METHOD OF PREPARATION OF FUEL GAS Russian patent published in 2016 - IPC F25J3/00 B01D3/28 C10G5/06 

FIELD: oil and gas industry; energy.

SUBSTANCE: invention relates to a process for the preparation of compressed fuel gas for gas turbine power plants and can be used in the petroleum industry and energetics. Method comprises compressing, cooling, and gas separation. Gas absorption before compression plunged circulating absorbent high pressure to obtain a low pressure absorber. Mixed gas of weathering and carrying absorbent high pressure. Obtained compressate is compressed, cooled and separated to give a condensate, which is reducing and is separated from the product gas weathering stability condensate and compressed gas, which is subjected to absorption cooled absorbent low pressure to obtain fuel gas and absorbent high pressure, partitioned into circulating and balance.

EFFECT: invention reduces the loss of hydrocarbon C₅₊ with a fuel gas and obtain stable condensate.
