Kentucky Power H.L. Spurlock Station had to carefully consider limestone cost and delivery charges from all suppliers. H.L. Spurlock wanted a low-cost limestone that could scrub Illinois Basin Coal effectively.
H.L. Spurlock has made the decision to try mostly Carmeuse’s Maysville CleanCalco® LS in the limestone scrubbers, a limestone containing 8% magnesium carbonate (MgCO3)
The use of high magnesium carbonate content of CleanCalco® LS in limestone scrubbers can be proven to effectively remove SO2.
