The picture shows the completion situation of Zhenhai bubbling bed residue welding forging welding hydrogenation reactor.
On April 11th, the world's largest petrochemical technology equipment produced by China First Heavy Industry, the Zhenhai boiling bed residue forging welding hydrogenation reactor was completed and shipped at a major nuclear power petrochemical company in China. The successful manufacturing of this equipment marked China’s large tonnage. Petrochemical equipment manufacturing technology once again led the international, at the same time, it also added new momentum for the vigorous development of China's petrochemical industry.
It is understood that the Zhenhai Fluidized Bed Residue forging and welding hydrogenation reactor is the core equipment in the 2.6 million tons/year upgrading and upgrading project of Zhenhai Refining & Chemical Branch of China Petroleum & Chemical Corporation. After the project is completed and put into production, it can be maximized. The residual oil conversion rate, which reduces the delayed coking load, will bring new growth points for the Zhenhai Refinery Branch. The reactor shell has a weight of 2400 tons and a diameter of nearly 5 meters. Compared with traditional fixed-bed hydrogenation equipment Hydrogenation in fluidized bed has the advantages of wide adaptability to feedstock oil, uniform temperature in the reactor, long operating cycle, on-line addition and discharge of catalysts, etc. It is an important direction for the future development of hydrogenation process.
China's major nuclear power petrochemical company conscientiously implemented the new development concept, insisted on high quality development, and based on its strong R&D capability, advanced manufacturing technology, and outstanding market performance, it had undertaken the development task of the equipment in 2016. During the manufacturing process, Because the ebullated-bed reactor structure is different from traditional fixed-bed reactors, the installation process of its internals is complicated, the processing precision is high, and it is extremely difficult to manufacture. The vast number of process technologies and front-line employees are closely involved in project management, strict process specifications, serious quality control, and exquisite The manufacturing technology, solid work style, has overcome the reactor long, overweight, can not overall heat treatment, ray detection, non centripetal take over, stainless steel to take over all positions of dissimilar steel welding and many other problems, quality and efficient completion of the manufacturing tasks. Its successful manufacturing not only enhanced China’s professionalism, innovation capability and core competitiveness, but also refreshed the research and development performance of China’s oversized tonnage hydrogenation reactors, which has contributed to the nationalization of major petrochemical technology equipment. New chapter.
