Abstract
A delayed coker control system wherein the hydrocarbon feed flows to the coker furnace is automatically limited to the lowest of the maximum allowable flows to avoid furnace zone flooding, an air-limited furnace and overfilling of the coke drum in the cycle time. Flows among the separate furance zones are adjusted to balance heat loads on each stream and to redistribute excess flow to non-flooding zones.
