FIELD: oil and gas industry.
SUBSTANCE: at combustible gas enrichment in order to limit adsorbent destruction/breakage without an increase in time required for the pressure balancing stage this stage is carried out with an installed open valve V4 for opening/closure of a pressure-balancing channel introduced into a pressure-balancing channel L4 upon the adsorption stage performed in the first adsorption tower U1 and desorption stage performed in the second adsorption tower U2 connected/related to the first adsorption tower by the pressure-balancing channel L4.
EFFECT: combustible gas enrichment in order to limit adsorbent destruction/breakage without the increase in time required for the pressure balancing stage.
