Abstract
A compressed gas dryer and a method of drying compressed gas, particularly air, which method comprises: intimately contacting a high-pressure, wet, compressed gas stream having a high relative humidity with a hygroscopic liquid absorbent miscible with the water to be removed, and separating the liquid absorbent and compressed gas to provide a wet liquid-absorbent mixture containing the water removed from the gas and a dry compressed gas stream; reducing the liquid-absorbent mixture to a lower pressure than the high pressure of the wet compressed gas stream; intimately contacting the liquid-absorbent mixture with a portion of the dry compressed gas stream at the lower pressure and separating the liquid absorbent from the gas stream to provide a dry liquid absorbent and a lower-pressure gas stream containing the water removed from the liquid-absorbent mixture; recycling the dry liquid absorbent for use in the contacting of the wet compressed gas stream; removing the wet lower pressure gas stream at the lower pressure; and purging the wet lower-pressure gas stream to the atmosphere.
