Abstract:
Processes for quenching coke in a coke drum of a delayed coker unit that more thoroughly cool the coke, eliminate hot spots in the coke bed, and remove residual hydrocarbons from the coke prior to venting the coke drum may comprise a ramp quench phase and a pressure quench phase after the ramp quench phase. During the ramp quench phase, the coke drum internal pressure may rise to a maximum pressure level and then fall to a transitional pressure level. At least one control valve may be actuated at the transitional pressure level to increase the coke drum internal pressure from the transitional pressure level to a pulsed pressure level of the pressure quench phase.
