BURNING GASES DRYING METHOD Russian patent published in 2015 - IPC B01D53/04 B01D53/26 

FIELD: oil and gas industry.

SUBSTANCE: method includes adsorption dehydration of separated gas, adsorbent regeneration by blowing with heated gas, to this end pressure is decreased up to pressure below adsorption pressure with production of reduced gas, absorbent is blown with the first part of oxidizing gas until the first blowdown gas is received, then adsorbent is blown with the second part of oxidising gas and further with reduced gas until the second blowdown gas is received, pressure is increased up to adsorption pressure and adsorbent is cooled down by blowing with dry gas, which is later on is mixed with the remaining part of dry gas; at that mixture of the first and second blowdown gases is subjected to catalytic oxidation with oxygen-containing gas with obtained oxidizing gas, which is divided into two parts and sent to adsorbent blowing.

EFFECT: reduced energy consumption, improved fire and explosion safety and ecological safety.
