Improving Tube Furnaces for Delayed Coking

摘要

Abstract The influence of the parameters of a tube furnace for delayed coking on the pressure drop, critical temperature, and salt content of the coil is investigated. A mathematical model of the furnace is proposed. Optimal coil parameters are determined. The parameters of the furnace have a significant influence on the operational safety, the coke buildup within the tubes, and the interval between repairs.
