METHOD OF COMPRESSED GAS DEHYDRATION Russian patent published in 2002 - IPC

FIELD: compressor plants; applicable in dehydration of compressed gas. SUBSTANCE: method of dehydration of compressed gas pumped by compressor to receiving accumulator includes passage of compressed gas through two alternately operating adsorbers periodically changing over from dehydration to regenerating conditions. Regeneration is effected by heating of adsorber and removal of desorbed components. Adsorber is heated with preliminarily its unloading up to temperature of 150-170 C, after which removal of desorbed components is performed by periodic communication of adsorber with atmosphere by pulses of 5-10 s with interval between pulses of 5-10 min, and heating is continued up to attaining temperature of adsorber of 360-380 C. Then heating and periodic communication of adsorber with atmosphere are discontinued. EFFECT: higher economy of process of gas dehydration. 1 dwg
