ADSORPTION UNIT Russian patent published in 2024 - IPC B01D53/04 C07C7/12 F25J3/02 

FIELD: gas industry.

SUBSTANCE: invention can be used for preparation of hydrocarbon gases. A distinctive feature of the adsorption installation is that the regeneration exhaust gas outlet after the throttle is connected through the first flow line of the cooled regeneration exhaust gas with a propane refrigerator, which is connected through the second flow line of the cooled regeneration exhaust gas to a low-temperature separator equipped with the first cooled separation gas outlet line and the first cooled hydrocarbon condensate discharge line. The first cooled separation gas outlet line is connected to the second recuperative heat exchanger, which is also connected on one side with the removal of hydrocarbon condensate from the high-pressure separator, and on the other hand, through the second cooled separation gas outlet line, it is connected with the stabilization gas line and through the second line of cooled hydrocarbon condensate from the high-pressure separator it is combined with the first line for removing cooled hydrocarbon condensate through a pump from the low-temperature separator into the common flow, which is connected to the upper part of the condensation and stripping column.

EFFECT: ensuring the production of additional amounts of liquid C₅₊ hydrocarbons.
