US Patent:

50614550, Oct 29, 1991

Filed:

Sep 28, 1990

Appl. No.:

7/590321

Inventors:

Harlan F. Brose - East Hartland CT
Alfred O. Brouillet - Somers CT

Assignee:

United Technologies Corporation - Hartford CT

International Classification:

B01D 5304

US Classification:

422122

Abstract:

An apparatus for removing carbon dioxide from a body of air by using a regenerative solid amine material arranged in beds 14(A-D) is disclosed. Air is directed through a first bed to adsorb the carbon dioxide therefrom. Steam is impelled by a compressor (24) into the first bed to desorb that bed, the steam forming a condensate on that bed. The compressor then creates a vacuum in the first bed which vaporizes the condensate therein, dewatering the first bed so that it may be reused to adsorb carbon dioxide. The compressor impels the vaporized condensate into a second bed to desorb the adsorbed carbon dioxide in the second bed.
