REMOVAL OF CO2 GREENHOUSE-GAS BY AMMONIA SCRUBBING

This paper provides preliminary results on the novel study of ammonia scrubbing for the removal of carbon dioxide from flue gas. Experimenta l results indicated the potential of CO2 reduction by NH3 scrubbing is very promising. The overall CO2 removal efficiencies could be above 9 5% under proper operation conditions. The absorption capacity of NH3 w as around 0.9 kg of CO2/ kg of NH3 reagent being used. This should be higher than that by a MEA solution. The reaction products were analyze d and determined by X-ray diffraction analysis, SEM picture, and pH me asurements. All the measurements indicated that an ammonium bicarbonat e solution and its crystalline solids are the major products of reacti on.
