ABSTRACT:
A coking drum system is provided in combination with a process control unit wherein the rate of material delivered to a coking drum during a coking process timing cycle is monitored and the quantity of material received by the coking drum is continuously derived therefrom. Based on this derived quantity of delivered material, the quantity of feed material required to fill the drum to a preestablished level with coke, at the completion of the timing cycle, can be predicted. The flow rate of feed material to the coking drum is accordingly adjusted so that the amount of coke produced in the drum during one timing cycle is optimized.
