Abstract: The present invention is directed to aminosilicone solvent recovery methods and systems. The methods and systems disclosed herein may be used to recover aminosilicone solvent from a carbon dioxide containing vapor stream, for example, a vapor stream that leaves an aminosilicone solvent desorber apparatus. The methods and systems of the invention utilize a first condensation process at a temperature from about 80° C. to about 150° C. and a second condensation process at a temperature from about 5° C. to about 75° C. The first condensation process yields recovered aminosilicone solvent. The second condensation process yields water.
