Abstract
A method and an apparatus for separating acidic gases from syngas are capable of reducing the necessary power and are capable of obtaining high-purity COat a high recovery ratio. A purification method and a purification system of coal gasification gas using the method and the apparatus are also provided. An apparatus for separating acidic gases from syngas containing acidic gases of C02 and H2S, in order, converts CO in the syngas into C02, removes H2S contained in the syngas by using a solvent for physical absorption, removes physical solvent from the syngas followed by heating in a heat exchanger using the converted syngas heat, and removes C02 from the heated syngas by using a solvent for chemical absorption.
