The application of desulfurization and denitrification by the activated carbon for strand gas in TISCO. This paper introduces technological parameters and process flowsheet of the designing, the selection of main equipment and operative condition for the hot gas generator system on the generator. The activated carbon could be regenerated with hot gas for the recycled use. The regeneration effect of activated carbon is good. The environmental protection is very obvious effects，and economic benefit is high. This technique which can immensely reduce the energy consumption, and comprehensive utilization of strand gas wastes. This immensely cut the operational costs, and showed its wide application value.
