PROMOTER ENHANCED CHILLED AMMONIA BASED SYSTEM AND METHOD FOR INCREASING PRECIPITATION OF AMMONIUM BICARBONATE SOLID PARTICLES IN REMOVAL OF CO2 FROM FLUE GAS STREAM

摘要

The invention provides a method of increasing precipitation of arnmonium bicarbonate solid particles from an ammonia solution in a chilled arnmonia based system for the removal of CO2 from a flue gas, the method comprising: adding a promoter including one of an amine and an enzyme to the arnmonia solution, thereby increasing precipitation of ammonium bicarbonate solid particles from the ammonia solution.
