PLANT (VERSIONS) AND SYSTEM (VERSIONS) FOR STRIPPING ASSOCIATED PETROLEUM GAS, METHOD OF STRIPPING ASSOCIATED PETROLEUM GAS Russian patent published in 2020 - IPC F25J3/00 

Abstract RU 2722679 C1

FIELD: technological processes.

SUBSTANCE: invention relates to techniques for preparing hydrocarbon gas, specifically to fractional distillation of hydrocarbon gas in order to obtain liquid hydrocarbon products and dry stripped gas, and can be used in oil and gas producing and oil and gas refineries. System for topping associated petroleum gas (APG) includes in series connected by pipeline heat exchanger of preliminary cooling, primary separator, adsorption drying unit, recuperative heat exchange device, condenser-evaporator, secondary separator, a rectification unit comprising a rectification column and a reboiler, as well as a control and monitoring unit configured to receive signals from control elements and supply control signals to control elements. Adsorption drying unit has an outlet for regeneration gas, an inlet and an outlet for the flow of APG and an input for a stream of dry stripped gas (DSG), which contains a flow rate regulator DSG and is connected to a DSG flow distribution assembly.

EFFECT: high efficiency of stripping the APG stream, broader range and high accuracy of extracting target hydrocarbons from the APG stream, as well as high thermodynamic efficiency and reduced weight and size.
