Removal of sour gases from gas mixtures containing them

There is an absorbent mixture usable for the removal of sour gases from gas mixtures. The mixture has at least one organic base having a pKb (in water) less than or equal to 3.2; at least one alcoholic solvent of general formula R(OH)n having a boiling temperature above or equal to 100° C. at ambien...

Zusammenfassung:	There is an absorbent mixture usable for the removal of sour gases from gas mixtures. The mixture has at least one organic base having a pKb (in water) less than or equal to 3.2; at least one alcoholic solvent of general formula R(OH)n having a boiling temperature above or equal to 100° C. at ambient pressure, wherein R is a linear or branched saturated alkyl group having a number of carbon atoms between 2 and 20 and n is a whole number varying between 1 and 20; an aprotic polar solvent having a dielectric constant ε at 25° C. greater than or equal to 30, a viscosity μ at 25° C. less than or equal to 14 cP, preferably less than or equal to 12 cP; and a boiling temperature at normal pressure equal to or above 130° C. There is also a process for the removal of sour gases using the absorbent mixture.
