SYSTEM FOR OIL GAS ABSORPTION DEHYDRATION, TREATMENT AND LOW-TEMPERATURE SEPARATION Russian patent published in 2013 - IPC F25J3/00 B01D53/02 

FIELD: oil and gas industry.

SUBSTANCE: system contains bank of oil gas absorption dehydration unit equipped with absorbers with zeolite and low-temperature condensation unit equipped with gas cooler. The system contains a cooling unit connected by coolant feed and discharge pipes and treated gas cooler of low-temperature condensation unit, heating unit and unit for high-temperature heat medium cooling connected by pipelines to absorption dehydration unit and gas treatment unit. Absorbers are completed by at least two modules - the first and second modules; each of modules contain at least two absorbers connected in parallel by gas fee pipeline and treated gas extraction pipeline and by series-connected recycle gas feed pipeline and recycle gas extraction pipeline. Modules are interconnected in parallel by gas feed pipeline and treated gas pipeline, recycle gas feed pipeline and saturated recycle gas extraction pipeline and also by high-temperature heat medium feed pipeline and high-temperature heat medium extraction pipeline.

EFFECT: increasing output of treated gas, reducing quantity of zeolite used in absorbers, reducing water content in source gas and providing possibility of the system operation at low temperature and high pressure of gas.
