Title: ACID GAS COLLECTION SYSTEM AND ACID GAS COLLECTION METHOD USING SAME
Abstract:
An embodiment of the present invention relates to an acid gas collection system comprising: an absorption column for absorbing acid gas contained in exhaust gas into an absorbent to generate an acid gas-saturated absorbent; a first heat exchanger for increasing the temperature of the acid gas-saturated absorbent through first heat exchange between the acid gas-saturated absorbent and an absorbent discharged from the bottom of a stripping column; the stripping column for separating the acid gas-saturated absorbent into acid gas and an absorbent; a reboiler for supplying heat energy to the stripping column using steam; and a condensate water recycling apparatus for recycling steam condensate water discharged from the reboiler.
