English term or phrase:stripping tower
Fig. 1 is a plan view showing the schematic configuration of H2S removal means and CO2 removal
means in one embodiment of a conventional acidic gas separation apparatus using a physical absorption process.
As shown in Fig. 1, shifted gas after the CO shift reaction is introduced into an acidic gas absorption tower
101, and brought into contact with a solvent fed by a pump 102d. As a result, H2S is removed. The solvent
having absorbed H2S in the crude gas in the acidic gas absorption tower 101 is introduced into an acidic gas
stripping tower 106 through an acidic gas concentrating tower 104. In the acidic gas stripping tower 106, the absorbed acidic gas is stripped from the solvent by heating with a reboiler 109. The stripped acidic gas is exhausted as acidic gas after passing through a condenser 107. On the other hand, the solvent from which the acidic gas has been stripped is introduced into a CO2 absorption tower 111 through a pump 102b, a heat exchanger 103, and a cooler 110a.
