Abstract

PURPOSE: To spray the absorbent solution at a rate corresponding to variation of the harmful gas concentration, and to facilitate the maintenance of the apparatus, by adjusting the spraying rate of the absorbent solution on the basis of the temperature difference of the waste gas between the inlet and outlet of the absorption column and the concentration of harmful gas contained in the processed gas.
CONSTITUTION: If the spraying rate of absorbent solution is excessive, the temperature difference ΔT=T1-T0, between gas temperatures at the neighborhood of inlet 12 and outlet 18 of the absorption column, has relation to the absorption efficiency. The harmful gas concentration Wi at the inlet of absorption column is calculated from the absorption efficiency calculated from the temperature difference ΔT, and the harmful gas concentration Wo at the neighborhood of outlet of the absorption column. From this value Wi, the optimum spraying rate of absorbent solution is calculated and the control valve 30 is adjusted. If the spraying rate of absorbent solution is less than the saturable amount, the inlet harmful gas concentration Wi is calculated from the outlet harmful gas concentration Wo and the harmful gas concentration W to be absorbed in the absorption column which is to be obtained from the amount of influent waste gas Q and the spraying rate F of absorbent solution; after that, the valve 30 is adjusted similarly.
