ABSTRACT:
In the operation of a by-product coke oven, in order to provide a coking cycle that meets an aim push time and also includes a coke soaking period of pre-selected length, the method of obtaining a plurality of liquid catch specimens having condensed therein volatiles from samples of gas withdrawn from the oven; determining a light-transmitting value for such liquid catch specimens for the coke devolatilizing period and for the coke soaking period; determining the end of the devolatilizing period based upon the light-transmitting values so determined; and, if necessary, adjusting the heating rate of the coke oven on subsequent coking cycles. Apparatus for obtaining such liquid catch specimens, and for determining such light-transmitting values is disclosed.
