Abstract
A post-combustion carbon capture system is configured to remove carbon dioxide from a post-combustion feed stream. The post-combustion carbon capture system includes an absorption tower that is configured to produce clean gas with a reduced carbon dioxide concentration and loaded solvent from the post-combustion feed stream. The post-combustion carbon capture system further includes a stripper tower downstream from the absorption tower, and an ultrasonic degasification module configured to remove oxygen from the loaded solvent. In another embodiment, the ultrasonic degasification module is incorporated into a biogas processing system and configured to remove oxygen from a carbon dioxide-loaded solvent.
Claims15
A post-combustion carbon capture system configured to remove carbon dioxide from a post-combustion feed stream, the post-combustion carbon capture system comprising:
- an absorption tower, wherein the absorption tower is configured to produce clean gas with a reduced carbon dioxide concentration and loaded solvent from the post-combustion feed stream;
- a stripper tower downstream from the absorption tower;
- and
- an ultrasonic degasification module configured to remove oxygen from the loaded solvent.
A biogas processing system configured to remove carbon dioxide from a biogas feed stream, the biogas processing system comprising:
- a contactor column, wherein the contactor column is configured to produce sweetened gas and loaded solvent from the biogas feed stream;
- a stripper column downstream from the contactor column, wherein the stripper column receives the loaded solvent;
- and
- an ultrasonic degasification probe configured to remove oxygen from loaded solvent.
A method for removing carbon dioxide from a feed stream that includes carbon dioxide, the method comprising the steps of:
- contacting the feed stream with a carbon capture solvent to produce loaded carbon capture solvent;
- and
- degassing the loaded carbon capture solvent stream with an ultrasonic degasification probe to remove oxygen from the loaded carbon capture solvent stream to produce a degassed stream of carbon capture solvent.
