The test method is used for evaluating limestone sources for use in wet Flue Gas Desulfurization (FGD) applications by reactivity with Sulfuric acid.
A test is needed to compare the relative reactivity of limestone materials for use in wet flue gas scrubbing systems designed to remove sulfur dioxide from the flue gas. The tests currently used are often proprietary and customized to one type of flue gas system. These tests often use expensive equipment; are time consuming and rely on comparison to unavailable reference materials. Specific items for the work group to resolve are sample particle size, acid type and strength, pH, temperature, reference limestone and test measurement type and result.
KeywordsRelative reactivity, residual carbonate, 45 particle size, pH, FGD
