COMPRESSED GAS DRIER UNIT AND METHOD IMPLEMENTED WITH SAID UNIT Russian patent published in 2010 - IPC B01D53/26 

FIELD: process engineering.

SUBSTANCE: invention can be used in chemical and petrochemical industries. Proposed unit comprises compressed gas source 2, two high-pressure tanks 33 and 34 each having first inlet 37 and 38 and dry compressed gas bleed point 32. Two high-pressure tanks 33 and 34 accommodate at least two layers of absorbers 35 and 36. First layer 35 is made from water-resistant water absorber, while second layer 36 is no obligatorily made from water-resistant water absorber. Two high-pressure tanks 33 and 34 has second inlet 41 and 42 to feed compressed air for recovery of water absorber of first layer 35 due to heat of compression. Second layer of water absorber 36 is recovered using a portion of dry compressed gas.

EFFECT: possibility to have compressed gas very low dew point at lower power consumption.
