By analyzing the startup process,energy consumption,and material consumption of delayed coking units,summarizing good practices,and optimizing startup procedures;analyze the reasons for the difficult problems such as incomplete dehydration of the system during the startup process,circulating water in diesel and wax oil,frequent emptying of the bottom pump of the startup tower during wax-oil hot operation,frequent ignition of the heating furnace,frequent replenishment of startup diesel and wax oil during startup,and frequent emptying of the exhaust system pump during the preheating period of the first tower and parallel furnace,and propose improvement measures.
