EXHAUST GAS TREATMENT DEVICE WITH SIMULTANEOUS REMOVAL REACTION

摘要

The present invention relates to an exhaust gas treatment method and an exhaust gas treatment apparatus. The method and the apparatus are capable of collecting CO_2 while simultaneously removing NO_x and SO_x from the exhaust gas. To this end, a calcination of calcium carbonate is carried out. And then carbonatization of calcium oxide and sulfation reaction are carried out in two reactor by a circulation process while the reduction process of nitrogen oxide is carried out by char during the carbonatization and the sulfation reaction.
