METHOD FOR THE CAPTURE AND DISPOSAL OF CARBON DIOXIDE IN AN ENERGY CONVERSION PROCESS

An energy conversion process that also exports by-product CO2 at elevated pressure where a fuel gas feed stream is mixed with a reactant stream and additional CO2 is added to at least part of, the fuel gas feed stream, the reactant stream or both through desorption by contacting with a CO2-rich solv...

Beschreibung
Zusammenfassung:	An energy conversion process that also exports by-product CO2 at elevated pressure where a fuel gas feed stream is mixed with a reactant stream and additional CO2 is added to at least part of, the fuel gas feed stream, the reactant stream or both through desorption by contacting with a CO2-rich solvent stream in a first stage contactor to produce a mixed feed gas stream and a CO2-lean solvent stream; passing said mixed feed gas stream to a chemical conversion step, where further CO2 is produced; chilling at least part of the products of said chemical conversion step, at a pressure of at least 10 bar to condense and partially remove CO2 as a liquid and thereby produce a CO2-lean gas stream; and passing at least part of said CO2-lean gas stream said to a second stage contactor where further CO2 is removed, by absorption in a solvent stream lean in CO2 derived from said CO2-lean solvent stream, to produce a product gas stream and a solvent stream rich in CO2 from which said CO2-rich solvent stream is subsequently derived.
