SYSTEM FOR CONTROLLING OPERATION OF DESULFURIZATION APPARATUS

摘要

A system for controlling the operation of a desulfurization apparatus equipped with an absorption column for bringing an exhaust gas into contact with an absorbing liquid so as to allow the absorbing liquid to absorb SO2 in the exhaust gas while discharging the desulfurized exhaust gas from which SO2 has been removed, which is further provided with a management unit for, while regulating the amount of SO2 removed from the exhaust gas within a definite range, setting the feeding rate of the absorbing liquid to the absorption column and the feeding rate of a material constituting the absorbing liquid in such a manner that an evaluation index (E), which is calculated by subtracting the income market price of income items arising from the operation of the desulfurization apparatus from the expenditure market price of expenditure items arising from the operation of the desulfurization apparatus, is minimized.
