Abstract

Existing methods of assessing coke in production conditions are analyzed. Significant deficiencies are noted in the gravimetric method of determining the yield of volatiles and in methods of determining the temperature of the coke leaving the coking chamber. Assessment of coke on the basis of a modified method of determining the yield of volatiles (by volume) at 1150°C is proposed. In the coke shops at PAO Zaporozhkoks, samples of industrial coke are assessed by the proposed method. A close correlation is found between the yield of volatiles (by volume) and two important coking characteristics: the final temperature and the coking rate. Determination of the yield of volatiles by volume is currently used in the central laboratory at PAO Zaporozhkoks in continually assessing the coke produced and correcting the coking temperature.
