Abstract
Official abstract text for this publication.
The present invention provides a method of increasing the efficiency of exothermic CO 2 capture processes. The method relates to withdrawing heat generated during the exothermic capture of CO 2 with various sorbents via heat exchange with a working fluid. The working fluid is provided at a temperature and pressure such that it is in the liquid state, and has a vaporization temperature in a range such that the heat arising from the reaction of the CO 2 and the sorbent causes a phase change from liquid to vapor state in whole or in part and transfers heat from to the working fluid. The resulting heated working fluid may subsequently be used to generate power.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for increasing energy efficiency of CO 2 capture from a fluid stream containing CO 2 , comprising: contacting a CO 2 -containing fluid stream with a sorbent in an adsorber such that the CO 2 reacts with the sorbent so that at least a portion of the CO 2 is removed from the fluid stream and heat is generated; withdrawing heat from the adsorber via heat exchange with a pressurized, liquid working fluid having a vaporization temperature in a…
