Abstract: Delayed coking units are important units for refineries to choose inferior raw materials in order to reduce the processing cost of raw materials. Coke cooling overflow and blowout water storage tank (D2403) is one of the keyatmospheric storage tanks in the unit. Theconstruction quality of the storage tank is directly related to its service life. Based on the specific installation engineering practice of D2403, this paper analyzes and studies the related technologies for installation construction of steel vertical storage tanks. It also studies the method and steps for installation construction and related processes principles. These provide reference for further improvement of the construction quality of storage tanks. Meanwhile, these have certain reference significance for the safe use of storage tanks.

Key words: delayed coking, coke cooling overflow, blowout water storage tank, construction technology, installation, welding
