Modern coker designs incorporate features that maximize liquid yields, enhance safety, and reduce emissions. Careful engineering of delayed cokers can as much as eliminate liquid effluents. The delayed coking process will play an increasingly important role in the modern refinery, because of its ability to convert heavy vacuum residues to distillates and petroleum coke. The flexibility inherent in delayed coking permits refiners to process a wide variety of crude oils, including those containing heavy, high-sulfur resides. These crudes frequently are bought at a discount, and if economically convertible to light distillates, can be a substantial factor in the refiner's cash flow development. The paper discusses specialty coke products, fuel-grade cokers, design trends, fractionators, coke-handling systems, and environmental impacts, including fugitive coke dust, vapor recovery, heater emissions, wastewater reuse, and waste oil disposal.
