Title: Results of thioclear testing: Magnesium-lime FGD with high SO{sub 2} removals and salable by-products

Abstract

Wet scrubbing is the leading proven commercial post-combustion FGD technology available to meet the sulfur dioxide reductions required by the Clean Air Act Amendments. To reduce costs associated with wet FGD, Dravo Lime Company has developed the ThioClear process. ThioClear is an ex-situ forced oxidation magnesium-enhanced lime FGD process. The ThioClear process differs from the conventional magnesium-enhanced lime process in that the recycle liquor has minimal suspended solids and the by-products are wallboard quality gypsum and magnesium hydroxide, and excellent reagent for water treatment. The process has demonstrated sulfur dioxide removal efficiencies of 98% in both a vertical spray tower and a horizontal absorber operating at gas velocities of 16 fps and 23 fps, respectively. This paper reports the optimization studies and associated economics from testing being conducted at Dravo Lime Company`s pilot plant located at the Miami Fort Station of The Cincinnati Gas and Electric Company.
