Title:
APPARATUS FOR ACQUIRING SLURRY CONCENTRATION, METHOD FOR ACQUIRING SLURRY CONCENTRATION AND METHOD FOR REMODELING FLUE GAS DESULFURIZATION FACILITY
Document Type and Number:
WIPO Patent Application WO/2021/206166
Kind Code:
A1
Abstract:
This apparatus for acquiring slurry concentration comprises: a first pressure acquisition unit which is configured so that, when the exhaust gas pressure or atmospheric pressure in a flue gas desulfurization facility is set as a reference pressure, a first pressure, said first pressure being based on the reference pressure at a first height position of an absorbing liquid stored in a storage unit formed inside the flue gas desulfurization facility, is acquired; a second pressure acquisition unit which is configured so that, when the exhaust gas pressure or atmospheric pressure in the flue gas desulfurization facility is set as a reference pressure, a second pressure, said second pressure being based on the reference pressure at a second height position, which is different from the first height position, of the absorbing liquid, is acquired; and a slurry concentration estimation unit which is configured so that the slurry concentration of the absorbing liquid is estimated on the basis of the first pressure acquired by the first pressure acquisition unit and the second pressure acquired by the second pressure acquisition unit.
