Abstract
Systems and methods for reducing the energy requirements for carbon dioxide capture are described. Heat from system processes, such as steam condensation and hot flue gas, is utilized to heat reflux liquid utilized in release of carbon dioxide from absorbent solvent.
Claims19
A system for reducing energy requirements of a carbon dioxide (CO2) capture process in a plant, comprising:
- a stripper configured to (a) receive a rich solvent, steam, and a reflux stream, and (b) produce a lean solvent and an upper product comprising CO2;
- a condenser configured to receive at least a portion of the upper product and produce a condensed stream;
- and
- a heat exchanger configured to receive at least a portion of the condensed stream, and allow for heat exchange contact of the portion of the condensed stream with a heat exchange medium to produce the steam.

A system for reducing energy requirements of a carbon dioxide (CO2) capture process in a plant, comprising:
- a stripper configured to (a) receive a rich solvent and a reflux stream, and (b) produce an upper product comprising CO2;
- a condenser configured to receive at least a portion of the upper product and produce a condensed stream;
- an accumulator configured to receive the condensed stream and produce a condensate stream;
- and
- wherein at least a portion of the condensate stream is fed to the stripper as the reflux stream.
