(US5066314-A)      Removal of acid components from a gas mixt. using an organic absorbent based on polyglycol ethers comprises (a) absorbing acid components of the gas mixt. by countercurrent contact of gas mixt. with absorbent in an adsorber at increased pressure and temp. below 20 deg. C, (b) discharging the resultant mixt. from top of absorber; (c) discharging absorbent from bottom of absorber to an expander of pressure lower than absorber, and discharging most of acid components; (d) discharging absorbent from expander to top of a desorber at lower pressure than expander; (e) discharging remaining acid components by countercurrent flow of air or N2 gas from the bottom to reduce acid content of absorbent to max. 0.5 Nm2.m3 and extracting absorbent from bottom of desorber; (f) supplying a major amt. of absorbent to a refrigerator, and cooling to below 20 deg. C,and' supplying cooled absorbent to top of absorber for re-use; (g) supplying remaining absorbent, after heating, to the top of a dehydration vessel at 80-150 deg. C and 0.8-1.3 atmos, where moisture contained in the absorbent is discharged by countercurrent contact with a stripping gas; and (h) joining dehydrated absorbent with (f) to be cooled.    USE/ADVANTAGE -   For removal of CO2 from gas mixts.. Reduces power and reagent consumption whilst retaining stability of compsn.. @(6pp)    (EP456877-B1)      Method of removal of acid components from a gas including their absorption with an organic solvent based on ethers of polyglycols at an elevated pressure followed by regeneration of the saturated absorbent and by dehydration of a part of the regenerated absorbent by heating, which is characterised in that the dehydration of the absorbent is carried out by the combination of stripping with a gas and heating at the temperature which is lower than the boiling point of the solvent at the 0.8 to 1.3 atm. by 80 to 150 deg.C.    (RU2028815-C1)      Acid components are removed from a gas by a new method which includes their absorption with an organic solvent based on ethers of polyglycols at raised pressures. The satd. absorbent is regenerated and a part of the regenerated absorbent is dehydrated by heating. The dehydration is achieved by the combination of stripping with a gas and heating at a temp. lower than the b.pt. of the solvent at 0.8-1.3 atm. by 80-150 deg. C. The stripping agent gas = air, N2, H2, 02, argon, methane or their mixts.    USE/ADVANTAGE -   The method is useful for the removal of CO2 from gas used in ammonia synthesis. The purified gas is obtd. with reduced power consumption and less reagents.
