Abstract:

According to the feature of containing SO2 and H2S in semi-coke gas, a new semi-coke desulfurization 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 SO2 in the gas quickly, then SO2 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.
