Regenerative CO2 Absorbent.

摘要

Acid gases, such as CO2, can be extracted from a gaseous feed stream by contacting the exhausted inlet gas with an aqueous solution of 3-Amino-1,2 Propanediol, separating the regenerated feed stream from the aqueous amine solution and the acid gases dissolved therein, and further separating these dissolved acid constituents from the diol solution; finally, repeating the above cycle indefinitely.
