Abstract

The invention discloses coking delay equipment and method capable of optimizing product quality and liquid yield, and belongs to the technical field of hot processing of heavy oil. The equipment is composed of a raw oil feeding line, a fractionating tower, a heating furnace feed pump, a heating furnace, a heating furnace transfer line, a coke chamber feed four-way valve, a coke tower, a coke tower roof anti-coking device, a reaction oil gas pipeline and the like which are connected in sequence. According to the equipment and method disclosed by the invention, a novel flow design and a control method are adopted, so that the defects that coke powder is carried in a product in a conventional coking delay process flow, the quality of wax oil products is poor, the heavy wax oil section of the fractionating tower is easily coked, the coke tower reaction oil gas pipeline is easily coked, the device circulation ratio is difficult to regulate and the like can be overcome, the operation becomes flexible and reliable, and the optimized production requirement of the whole plant can be fulfilled in the actual operation, the coking product quality and liquid yield can be optimized, and the economical benefit of the whole plant can be increased.

Description

technical field

[0001] The invention belongs to the technical field of heavy oil thermal processing, and in particular relates to a delayed coking device and method capable of optimizing product quality and liquid yield. Background technique

[0002] Delayed coking process is a thermal processing process of heavy oil. After the heavy oil is rapidly heated to the reaction temperature through a heating furnace, it is quickly transferred to the coke tower, and the "delayed" thermal cracking and condensation reaction is carried out in the coke tower. The high-quality oil is converted into dry gas, liquefied petroleum gas, coker naphtha, coker diesel oil, coker wax oil, coke, etc. The product quality and liquid yield of the delayed coking unit are the direct economic benefit indicators to measure the unit. The product quality and liquid yield are a complex relationship. Generally, when the product quality is better, the liquid yield is relatively low, and the liquid yield is rela...
