FIELD: oil and gas industry.
SUBSTANCE: method includes compression of the dehydrated gas, and compressed gas dehydration by cooling under dephlegmation conditions with production of the condensate and dephlegmation gas, and passage through the adsorber with production of the dehydrated compressed gas, and further adsorbent regeneration. At that the dephlegmation gas is dehydrated in the unit comprising three adsorbers, each of them contains the adsorber bed, the dephlegmation gas is subjected to the dehydration in the first adsorber and deep dehydration in the second adsorber, and the adsorber regeneration is performed in the third adsorber, at that the adsorbers are cyclically switched over.
EFFECT: invention ensures effective gas dehydration and reduced volume of the adsorber charge.
