FIELD: energy; oil and gas industry.
SUBSTANCE: invention relates to a method of fuel gas 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 is preliminary absorbed under negative temperature gradient with the help of absorbent high pressure. Absorbent is of low pressure, which is separated into circulating and balance, and gas mixed with balance absorbent low pressure compressed, cooled and separated with production of condensate and gas, which is subjected to absorption of cooled circulating absorbent in conditions of negative temperature gradient to produce absorbent and fuel gas.
EFFECT: reduced losses of hydrocarbons C5+ with fuel gas.
