This study has been carried out to evaluate the effect on desulfurization of flue gas by Mg(OH)₂in steam-power cogeneration plant. We investigated the effects of desulfurizatin on the temperature of flue gas and pH of circulation water in aborber. The desulfurization installations of flue gas in cogeneration and thermoelectric power plant will be increased every year because of stricted environmental regulation in Korea. Some conclusions obtained are summerized as follows ; 1. With regard to running cost, Mg(OH)₂ absorbent for desulfurization of flue gas snowed more economic than Ca(OH)₂. 2. While bunker-C oil with 1.6% sulfur was used, desulfurization of flue gas by Mg(OH)₂ was performed and then SO₂ content in the exhausted gas was under 50 ppm. 3. In flue gas desulfurization, the optimum condition on the temperature and pH was 55-60℃ and 6 respectively, then efficiency was 96%.

The objective of this study was to oxidize chloromethanes waste with pyrolytic incineration unit. This experiment was carried out in actual plant. We have studied incineration temperature VS. removal rate of waste Liquid, removal of Hcl and Cl₂ in the flue gas. The results obtained were as followa : 1) In combustion condition for the temperature of 950℃ and the residence time of 1, 2 seconds, waste chloromethanes and cyan compounds were nearly decomposed. 2) The removal of Hcl and Cl₂ for the use of NaOH in the flue gas was very excellent. 3) The scrubbing of the dust was effected with NaOH solution.
