SYSTEMS AND METHODS OF CAPTURING CARBON DIOXIDE AND MINIMIZING PRODUCTION OF CARBON DIOXIDE

摘要

A method of capturing carbon dioxide emitted by a power plant includes providing a reactor vessel having a shell with a top and a bottom, introducing an exhaust gas stream into the reactor vessel, the exhaust gas stream containing carbon dioxide, whereby the exhaust gas stream rises toward the top of the reactor vessel. The method includes introducing an organic sorbent solution into the reactor vessel near the top of the reactor vessel so that the organic sorbent solution falls toward the bottom of the reactor vessel, mixing the rising exhaust gas stream with the falling organic sorbent solution to precipitate calcium carbonate, and removing the calcium carbonate from the bottom of the reactor vessel, whereby the calcium carbonate includes the carbon dioxide from the exhaust gas stream.

1. A method of capturing carbon dioxide emitted by a power plant comprising:
providing a reactor vessel having a shell with a top and a bottom; introducing an exhaust gas stream into said reactor vessel, said exhaust gas stream containing carbon dioxide, wherein said exhaust gas stream rises toward the top of said reactor vessel; introducing an organic sorbent solution into said reactor vessel near the top of said reactor vessel so that said organic sorbent solution falls toward the bottom of said reactor vessel; mixing said rising exhaust gas stream with said falling organic sorbent solution to precipitate calcium carbonate; and removing said calcium carbonate from the bottom of said reactor vessel, wherein said calcium carbonate includes said carbon dioxide from said exhaust gas stream.
