Abstract
This chapter describes methods of analysis for the major chemical products in the coke oven gas and the analysis of fixed gases flowing from the top of the coke oven to the analysis of sulfur compounds and hydrogen cyanide in the treated gas. The latter is important in the desulfurization of coke oven gas to meet EPA regulations for concentrations of inorganic and organic sulfur compounds in the treated gas prior to its use as a fuel. The length of a coking cycle for carbonizing of coal in an oven is determined from experience and the range of the flue temperature. Most coke plants also have experimental coke ovens to determine coking cycles for variable coal mixes and at different flue temperatures. The chapter describes the analysis of the gas flowing from the oven into the standpipe, which is a method to determine the end of coking cycle and discusses the analysis of ammonia in coke oven gas entering the ammonia saturators by wet chemical methods and by gas chromatography.
