The non-blast furnace coke produced in the shaft ovens of the Angarsk Semi-coking Plant is used principally in gas generator ovens and partially as a carbonaceous reducing agent in the ferroalloy process. The sulfur content of this coke is not limited by the standards documents, but it is significant, especially in the production of process gases. In a number of recent years the sulfur removal system of the gasification divisions have been experiencing difficulties, not achieving the assigned gas purification parameters, with a resulting H/sub 2/S concentration in the purified gas of 300-700 mg/m/sup 3/ as compared to the standard of 50. Realizing that in the gasification practically all the organic matter of the coke, including the sulfur, enters the gas, the impairment in the quality of the sulfur removal is related to the increase in the sulfur content of the coke. Thus, an analysis of the results was conducted for the determination of the sulfur content of the industrial coke as a function of the sulfur content of the original coal and in relation to the H/sub 2/S concentration in the semicoking gas and in the process gases during gasification of the coke. Results of the analysis are presented.
