METHOD OF PROCESSING OF ASSOCIATED OIL GAS AND FACILITY FOR IMPLEMENTATION OF THIS METHOD Russian patent published in 2008 - IPC F25J3/02 B01D5/00 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to processing of oil gases by method of low temperature condensation. The method of processing of associated oil gas incorporates compression of source associated oil gas, its cooling and separation with production of dry gas and gas condensate in which, according to the invention, a two-stage separation is performed; gas condensate is subject to distillation in a rectifying column with production of a propane-butane fraction and a stable gas condensate; while the propane-butane fraction is cooled and condensed. A facility for implementation of this method incorporates a compressor connected via at least one heat exchanger with a separator, reservoirs and pumps, which according to the invention is equipped with a second separator connected with the first separator gas output; gas condensate outputs of separators are connected with an input of the rectifying column, the distillate and stable gas condensate outputs of which are connected to corresponding heat exchangers. Preferably slit separators are to be used.

EFFECT: receiving of products of such qualitative characteristics which can be utilised as fuel without any further processing.
