METHOD OF PREPARING HYDROCARBON GAS AND APPARATUS FOR REALISING SAID METHOD Russian patent published in 2012 - IPC C01G5/00 B01D53/00 F25J3/00 

FIELD: chemistry.

SUBSTANCE: invention can be used in gas and oil industry. The apparatus for preparing hydrocarbon gas has a gas separation unit 1, a gas adsorption drying and gasoline extraction unit 2, a hydrocarbon stabilisation unit 3 and a compression unit 4. Unit 1 has separators and is fitted with a separated gas outlet I, a hydrocarbon condensate outlet II and a water outlet III. The gas adsorption drying and gasoline extraction unit 2 has adsorbers filled with silica gel and is fitted with a prepared gas outlet IV which is linked with a booster compressor station 5, a gas outlet V after adsorbent regeneration, a hydrocarbon condensate outlet VI and a water outlet VII. The regeneration gas used in unit 2 is a stream X. Hydrocarbon condensates from outlets II and VI are merged and fed into stabilisation unit 3 which is fitted with a stabilisation gas outlet VIII and an outlet IX for stable condensate, which is the end product. Stabilisation gases are taken for in-house needs or compression in unit 4 and subsequently fed into the stream of starting gas or into the stream of spent gas in outlet V or the stream of prepared gas in outlet IV.

EFFECT: high quality of preparing hydrocarbon gas to obtain additional products, reduced loss of desired hydrocarbon fractions.
