METHOD FOR REMOVING CARBON DIOXIDE FROM EXHAUST GAS FLOW AND INSTALLATION FOR COLLECTING CARBON DIOXIDE FROM EXHAUST GAS FLOW

摘要

1. A method of removing carbon dioxide from an exhaust gas stream, the process comprising the steps of: contacting said exhaust gas stream with a depleted amino-silicone absorbent in an amount sufficient to react with a substantial portion of the carbon dioxide present in said exhaust gas stream; forming a suspension comprising unreacted amino-silicone absorbent and carbamate compounds formed by the reaction of the indicated depleted amino-silicone absorbent one with said carbon dioxide; heating said suspension to a temperature sufficient to cause desorption of carbon dioxide from said carbamate compounds and regenerate depleted amino-silicone absorbent; keeping desorbed carbon dioxide gas separate from said exhaust gas stream; and the release of said gaseous carbon dioxide. 2. The method of claim 1, further comprising the step of cooling said exhaust gas stream prior to contacting said depleted amino-silicone absorbent. The method according to claim 1, wherein said contact stages of said exhaust gas stream with an amino-silicone absorbent and suspension formation occur in an absorber column. The method according to claim 3, further comprising the step of recycling the regenerated depleted amino-silicone absorbent to said absorber. The method of claim 1, further comprising the steps of exhausting the exhaust gas after said portion of the carbon dioxide has already been retained. The method according to claim 1, where the specified amino-cr
