Successful application of hydrocracking unit expansion energy upgrading technology

The expansion of the hydrocracking unit with the overall technology at the international advanced level and the upgrading of product quality technology were jointly developed by the Sinopec Fushun Petrochemical Research Institute, Zhenhai Refining & Chemical Company, and Luoyang Petrochemical Engineering Company, and the Zhenhai Refining & Chemical Company I Set of hydrocracking units for industrial applications. The reporter interviewed the Fushun Petrochemical Research Institute on July 13 that the technical industrial application results showed that the processing capacity of the device has been greatly improved, and the yields of heavy naphtha and hydrogenated tail gas are high, dry gas, liquefied gas, and light naphtha, etc. Low-yield products have low yields and reduce the device's hydrogen consumption.

According to reports, the hydro-cracking equipment expansion and product quality improvement application technologies with China's independent intellectual property rights have been granted six national invention patents, giving refineries and companies full play of the advantages of refining and chemical integration, further optimizing the supply of ethylene raw materials, and achieving The goal of "big chemical, big oil refining" provided technical support.

Zhenhai Refining I hydrocracking unit is the first large-scale hydrocracking unit independently designed and built in China, and the main equipment to achieve localization. In order to realize the overall goal of “big chemical industry and large oil refining”, the original hydrocracking unit needs The expansion and transformation will be carried out to increase the processing capacity from 1 million tons/year to 1.2 million tons/year. Under this circumstance, Fushun Petrochemical Research Institute carried out expansion and reconstruction of the hydrocracking series of the hydrocracking unit of Zhenhai Refinery I.

Researchers have successively developed high-activity hydrocracking pretreatment catalysts and hydrocracking catalysts with suitable activity, which improved the loading quality of catalysts, the effectiveness of catalysts, and optimized the operation of hydrocracking units, and solved the refinement of energy expansion transformations. Bottlenecks and temperature matching and other issues. The test results show that by adopting the combined hydrocracking catalyst system and its supporting process technology, the expansion and transformation target of the Zhenhai Refinery I hydrocracking unit was realized.

It is understood that hydrocracking technology has the characteristics of strong adaptability to raw materials, flexibility in production operations and product solutions, and good product quality, and it has become one of the most important heavy oil deep processing technologies in the modern refining and petrochemical industries. Fushun Petrochemical Research Institute has successively developed a large number of scientific and technological achievements and patented technologies with independent intellectual property rights, which have been widely used in domestic oil refining and chemical companies.
