<p>Disclosed is an apparatus for collecting acidic gas which can reduce costs in process operation. For example, the apparatus which collects acidic gas by receiving synthetic gas comprises a hydrogen-sulfide adsorbing tower for collecting hydrogen-sulfide through an adsorbent by receiving synthetic gas; and a carbon-dioxide adsorbing tower for adsorbing carbon-dioxide through the adsorbent by receiving synthetic gas from the hydrogen-sulfide adsorbing tower; and a heat exchanger for exchanging heat between synthetic gas applied from the top end of the hydrogen-sulfide adsorbing tower and synthetic gas applied from the top end of the carbon-dioxide adsorbing tower.</p> |
