Abstract
Ultra cleaning of combustion gas to near zero concentration of residual contaminants followed by the capture of COis provided. The high removal efficiency of residual contaminants is accomplished by direct contact cooling and scrubbing of the gas with cold water. The temperature of the combustion gas is reduced to 0-20 degrees Celsius to achieve maximum condensation and gas cleaning effect. The COis captured from the cooled and clean flue gas in a COabsorber () utilizing an ammoniated solution or slurry in the NH—COHO system. The absorber operates at 0-20 degrees Celsius. Regeneration is accomplished by elevating the pressure and temperature of the CO-rich solution from the absorber. The COvapor pressure is high and a pressurized COstream, with low concentration of NHand water vapor is generated. The high pressure COstream is cooled and washed to recover the ammonia and moisture from the gas.
