UNIT FOR PREPARING HYDROCARBON GAS FOR TRANSPORT Russian patent published in 2022 - IPC B01D53/02 

FIELD: gas industry.

SUBSTANCE: invention relates to a unit for preparing gas for transportation. Described is a unit for preparing hydrocarbon gas for transport, including control valves, separators, adsorbers, gas supply and discharge lines, filtering apparatuses, a furnace, throttle valves, regenerative heat exchangers, a filter separator, throttle valves, additionally containing a line for discharge of a part of the prepared gas, connected through a throttle valve with the regenerative heat exchanger, on one side communicating with the discharge of low-pressure gas from the low-pressure separator, and on the other side communicating through a line for supplying a cooled part of the prepared gas with a fuel gas separator and through a cooled low-pressure degassing gas line with a refrigerator connected with a flare separator, wherein the line for discharge of the wide light-hydrocarbon fraction is connected through a centrifugal pump with the line for discharge to the tank battery, and the gaseous phase line is connected with the low-pressure fuel network or with the line for discharge to the flare, wherein the line for discharge of the hydrocarbon condensate from the fuel gas separator is connected with the line for discharge of the hydrocarbon condensate from the medium-pressure separator to the low-pressure separator, and the gaseous phase line is connected with the fuel network.

EFFECT: increase in the environmental safety and resource conservation of the unit.
