METHOD OF ASSOCIATED PETROLEUM GAS FILTERING FROM HEAVY HYDROCARBONS AT LOW TEMPERATURES Russian patent published in 2008 - IPC F25J3/08 

FIELD: organic chemistry, oil industry.

SUBSTANCE: the invention relates to development of a method for associated petroleum gas filtering from heavy hydrocarbons at temperatures, with the possibility of subsequent burning in power plants. The produced petroleum gas is passed through the main pipeline obvoluted by a part of process water pipeline while the bypassing line of the gas pipeline is closed by a valve. Under low temperatures, heavy hydrocarbons are deposited on the walls of the gas line and absorbed by a replaceable zeolite filter. The polluted gas line is closed by a valve, the replaceable zeolite filter is removed for thermal regeneration. For the duration of the gas line closing, the associated petroleum gas is passed through a bypassing line. The pressure gauges installed before and after the pipeline part being cooled are used to determine the degree of pollution of the gas line. The usage of the invention will allow to create a method of associated petroleum gas filtering from heavy hydrocarbons at low temperatures, with the possibility of subsequent burning in power plants.

EFFECT: filtering of associated petroleum gas from heavy hydrocarbons at low temperatures, with possibility of subsequent burning in power plants.
