제목 H2S Removal with MDEA Process
초록 Internationally, strict regulation of air-pollutant emission is figured in an effort to dwindling global warming and environmental problems by UNFCCC & government. However, 145 % increase of coal-powered generation from 2000 to 2010 is expected due to Korean governmental policy to maintain the 30% portion of coal-fired power generation. At this point of time, Integrated Gasification Combined Cycle (IGCC) is spotlighted as one of the best alternative plan to increase 3-10 % generation efficiency and remove pollutants (>90%) in spite of an up-to-date high oil prices.
In flue gases, most sulfur (> 98 %) were emitted as H2S & COS from gasification reaction at high temperature and H2S should be removed below 20 ppm to prevent the facility corrosion & pollution. Usually, MDEA is used for this gas treatment as an absorbent because MEDA can absorb H2S selectively under proper operating conditions involving short contact times and can be used in concentrations up to 60% in aqueous solutions without appreciable evaporation losses because of low vapor pressure.
In this study, H2S capacity of absorption was measured using MDEA with several different conditions and, finally, the best condition for removing H2S in IGCC process was presented.
