MOBILE MODULAR UNIT FOR ASSOCIATED PETROLEUM GAS PROCESSING Russian patent published in 2022 - IPC F25J3/00 

FIELD: petroleum gas processing.

SUBSTANCE: invention relates to field installations for the processing of associated petroleum gas (APG) and can be used in oil fields to create mobile modular systems. The APG plant with the production of propane-butane fraction (PBF), stable gas condensate (SGK) and dry stripped gas (DSG) includes the first and second shut-off and control units connected by pipelines for supplying associated petroleum gas of the first and second separation stages with a gas flow measurement unit, the outlet of which through the second separation stage is connected by a pipeline to a filter-separator and a low-pressure compressor. The outlet of the first separation stage is combined with the outlet of the low-pressure compressor and is connected to the adsorption unit and the high-pressure compressor, the outlet of which is connected to the deethanization column containing the first reboiler, the outlet of which is connected to the fractionation column containing the second reboiler, at the outlet of which the SGK tank is installed. The head part of the fractionation column is connected to the reflux tank and then to the PBF tank. The outlet of the head part of the deethanization column is connected to the DSG flow from the adsorption unit and then goes to the outlet through the gas flow measurement unit.

EFFECT: invention makes it possible to increase the APG processing depth and increase energy efficiency.
