Design and Operation of 3MW Pilot Plant of $Mg(OH)_2$ Flue Gas Desulfurization Process

Korea Institute of Energy Research(KIER) has designed the 3MW pilot scale wet FGD process based on the experimental results of the bench scale FGD system which can treat 150 m3/hr of flue gases. The effects of process chemistry, packing material, and operating variables including L/G ratio, pH, scrubber pressure drop were investigated. In cooperation with Kyunggi Chemicals, the 3MW pilot scale plant was established on the industrial site at Onsan, Korea. This system has been operating since October 1999. This paper introduces an outline of the design features of the pilot plant and discusses its operational results.
