摘　　要：针对半焦煤气同时含有SO2和H2S的特性,结合现有脱硫工艺,提出了一种与高温炼焦有所不同的新的半焦脱硫工艺。该工艺先用石灰水快速洗涤煤气中的SO2,再用超重力机去除煤气中的H2S,从而使气体中总硫含量降低,满足了国家环保要求的排放标准。According to the feature of containing S02 and H2S in semi-coke gas, a new semi-colic desufurization process that is different from the process for high temperature cokemaking is put forward in combination with the existing desulfurization process. In the process lime water is first used to scrub the S02 in the gas quickly, then S02 is removed from the gas by super-gravity force machine so as to reduce the total sulfur content in the gas and to meet the required discharge standard of national environmental protection.
