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

FIELD: oil and gas industry; energy.

SUBSTANCE: installation of fuel gas preparation plant comprises a gas supply line and the output line compressate on which is placed a reflux condenser equipped with a fuel gas line output. As a reflux condenser is a unit absorption is mounted on the compressate line output posted node separation and cooling systems equipped with condensate drain line. On the gas supply line to the compressor assembly housed contacting associated with the node supplying absorbent absorption lines of high pressure and low pressure absorber O, which are sequentially arranged refrigerator and the branch for supplying the balance of the absorbent in the low pressure gas supply line to the compressor.

EFFECT: technical effect is to reduce the volumetric heating value of the fuel gas and reducing losses hydrocarbon C_5+.
