FIELD: oil-and-gas industry.
SUBSTANCE: method relates to natural gas cleaning by adsorbers and to recovery of the latter. Proposed method comprises forcing the stock containing natural gas through first adsorber to get the product including cleaned natural gas, recovery of second adsorber at heating stage and recovery of second adsorber at cooling stage. Heating stage comprises separation of a portion of stock contained in regeneration gas, feed of the latter into dehumidifier to remove water. Then, performed are regeneration gas heating and regeneration gas feed into second adsorber for its recovery. Cooling stage comprises, at the start of cooling stage, feed of at least a portion of fluid located in second adsorber to dehumidifier for water desorption from dehumidifier molecular sieve and, then, cooling of second adsorber.
EFFECT: minimised losses of natural gas used as regeneration gas.
