수산화마그네슘에 의한 배연탈황에 관한 연구 = Desulfurization effect of flue gas by Mg(OH)₂

다국어 초록 (Multilingual Abstract)

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%.
