METHOD OF GAS AND GAS CONDENSATE PREPARATION Russian patent published in 2015 - IPC B01D19/00 C07C2/00 C07C7/00 C10G5/00 E21B43/34 F25B43/00 

FIELD: chemistry.

SUBSTANCE: method includes separation of well production of gas-condensate field (I) with obtaining separation gas (II), water condensate (III), removed from device, and hydrocarbon condensate (IV), which is throttled, mixed with WLHF (V) and residue of catalysate separation (VI) and stabilised with obtaining stabilisation gas (VII) and trade condensate (VIII). Stabilisation gas (VII) is subjected to catalytic processing and separation with obtaining residue of catalysate (VI) and gas of catalysate separation (IX), the latter one is subjected to complex preparation with separation gas (II) with obtaining trade gas (X) and WLHF (V). If it is necessary, residual quantity of water condensate is separated at the stage of stabilisation and removed from installation.

EFFECT: increased duration of inter-regeneration period of catalyst work and simplification of stabilisation.
