Title:
SYSTEM FOR CONTROLLING OPERATION OF DESULFURIZATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2011/065118
Kind Code:
A1
Abstract:
A system for controlling the operation of a desulfurization apparatus, equipped with an electric dust collector for collecting coal ash in an exhaust gas and an absorption column for bringing the dedusted exhaust gas from the electric dust collector into contact with an absorbing liquid so as to allow limestone in the absorbing liquid to absorb SO2 in the dedusted exhaust gas while discharging the desulfurized exhaust gas from which SO2 has been removed, wherein the activity constant (K) of the limestone is calculated based on the SO2 concentration (S1) of the dedusted exhaust gas, the SO2 concentration (S2) of the desulfurized exhaust gas, the flow rate (S3) of the exhaust gas, the limestone concentration (C) of the absorbing liquid, the tank volume (V) of the absorbing liquid having been brought into contact with the dedusted exhaust gas and pooled in the absorption column, and pH of the absorption liquid, and the activation state of the lime stone is determined by comparing the aforesaid limestone activity constant (K) with a preset lime stone activity constant threshold (X).
