요약

A system for carbon dioxide capture from a gas mixture comprises an absorber that receives a lean solvent system stream (containing a chemical solvent, physical-solvent additive, and water) from the stripper, a stripper that receives the rich solvent stream from the absorber and produces the product carbon dioxide and the lean solvent through the use of a reboiler in fluid communication with a lower portion of the stripper, a condenser in fluid communication with a vapor outlet of the stripper, a cross-exchanger in fluid communication with a rich solvent system outlet from the absorber and a rich solvent system inlet on the stripper, and a splitter. The splitter is configured to separate the rich solvent system stream into a first portion and a second portion, where the first portion directly passes to the stripper and the second portion passes through the cross-exchanger prior to passing to the stripper.

대표청구항

1. A method for capturing carbon dioxide from a gas mixture comprising: contacting a gaseous stream comprising carbon dioxide with a lean solvent system, wherein the lean solvent system comprises a chemical solvent, a physical solvent, and water;absorbing at least a portion of the carbon dioxide in the lean solvent system to produce a rich solvent system;transferring the rich solvent system to a stripper, wherein the stripper comprises a reboiler;applying heat to the rich solvent system using the reboiler;generating a first vapor stream within the reboiler while incurring a heat rate to regenerate the lean solvent system, wherein the first vapor stream comprises steam and at least a portion of the carbon dioxide from the rich solvent system;passing a liquid stream from the reboiler to a flash vessel;producing, in the flash vessel, a second vapor stream and the lean solvent system;compressing the second vapor stream in a lean vapor compressor to produce a compressed lean vapor stream;passing the compressed lean vapor stream to the stripper; andtransferring an overhead stream from the stripper to a condenser.
