| Summary: | Ombilin power plant with 2×100 MW capacity, produces electricity for the region of West Sumatra and Riau. The coal consumption for electricity production is 45 tons/day with sulfur content of 0.77%. The estimated concentration of sulfur dioxide (SO2) emitted by stoichiometric reaction is 4,669 mg/Nm3 whereas SO2 emission quality standard for coal-fired steam power plant, based on Regulation of the Minister of Environment number 21/2008, is 750 mg/Nm3. To control the concentration of SO2, to meet the quality standard, a wet type of flue gas desulfurization (FGD) with a lime (CaO) reagent are used. The designed system consists of lime preparation (slaker), scrubber, and waste water handling (effluent hold tank, thickener, thickener overflow tank and filter belt press). The liquid and gas flow on the scrubber is designed on a countercurrent flow. To expand the absorption area, a packing material of Raschig ring with 2 inches diameter is used. The FGD was designed with 85% efficiency with a liquid requirement of 713.462 m3/hr and CaO need is 417.815 kg/hr. |
