REMOVAL OF NON-VOLATILE COMPOUNDS FROM AMMONIA-BASED CO2-ABSORBING SOLUTION

摘要

PROBLEM TO BE SOLVED: To provide a system arranged to remove carbon dioxide (CO) from a gas stream by bringing the gas stream into contact with a circulating ammoniated solution stream such that COis removed from the gas stream by the ammoniated solution stream.SOLUTION: A method of removing non-volatile compounds from the circulating ammoniated solution stream includes: introducing a portion of the circulating ammoniated solution stream into a gas-liquid separating device; and separating the introduced ammoniated solution into an ammonia rich gas phase and a liquid phase comprising the non-volatile compounds; and reintroducing the ammonia rich gas phase into the circulating ammoniated solution stream.
