ABSTRACT:
A method for removing sulfur dioxide from gas streams, comprising contacting the gas stream with the aqueous absorption liquid, transferring the liquid to another location, then mildly heating the liquid to recover the sulfur dioxide. This absorption liquid allows removal of 99.9% of the sulfur dioxide, the recovery of very pure sulfur dioxide, is resistant to upsets due to variations in the gas stream, and is cost effective.
