As refiners process heavier crudes, the delayed coker`s capacity must increase to fully load the light ends and conversion units. After the refinery is fully loaded, refiners look for ways to improve the efficiency of all operating units. For the delayed coker, this means more distillate or less coke production per barrel of feed. Unfortunately, the controlling parameters that allow a greater feed capacity conflict with maximum efficiency. The paper discusses incremental debottlenecking, the relationship of operating parameters, capacity increase by cycle time reduction, additional drums, fractionators, and blowdown system modifications.
