Flue Gas Desulfurization

A proposed new ASTM International standard will provide a method for a comparative evaluation of limestone sources available for use in flue gas desulfurization applications. The proposed standard, WK20129, Test Method for Evaluating Limestone for Use in Wet Flue Gas Desulfurization Applications by Reactivity, is being developed by Subcommittee C07.05 on Chemical Tests, part of ASTM International Committee C07 on Lime.

Power generation companies using or considering the use of wet limestone flue gas desulfurization and suppliers of limestone to the power industry would be the primary users of WK20129.

According to Michael Kroc, analytical investigator, Specialty Minerals Inc., and chair, Subcommittee C07.05, environmental concerns and issues of competition have driven the increased interest in flue gas desulfurization applications. The proposed standard will be a unified test method that will provide an alternative to the use of vendor-specific methods. “WK20129 should allow users to objectively compare the suitability of different sources and select the one that best meets their needs,” says Kroc.

All parties interested in FGD applications are invited to participate in the further development of WK20129. Kroc notes that the subcommittee is particularly interested in engaging FGD equipment manufacturers and consultants. Topics to be addressed by the task group for the proposed standard include sample particle size, acid type and strength, pH, temperature, reference limestone and test measurement type and results reported.
