Since 2010, Sinopec and Hubei Qiaoguang have maintained in-depth cooperation in areas such as the inner components of hydrogenation reactors and the adsorption towers of aromatic hydrocarbon separation devices. In 2010, the cold mold test for the inner components of the adsorption tower was completed, and in 2011, the first domestic high-precision grid inner components of the adsorption tower with independent intellectual property rights for the aromatic hydrocarbon separation device were successfully put into operation at Yangzi Petrochemical and were accepted by the Sinopec expert group. The product quality reached the international advanced level, replacing imports and filling the domestic gap. In 2011, the inner components of the diesel hydrogenation reactor for Sinopec Sichuan Petrochemical were completed. Over the past few years, the Chevron technology-based inner components for the RDS reactor provided by the company have received high praise from Chevron. In August 2011, the first batch of reactor inner components exported to Japan were all qualified after being inspected by experts from JSW, the world's leading manufacturer of reactor technology. In 2012, the inner components for the residue oil hydrogenation project of Sinopec Anqing Branch were completed. In 2017, the inner components for the wax oil hydrogenation reactor of Sinopec Jingmen Petrochemical were completed. Recently, the company is currently manufacturing the inner components for two hydrogenation reactors at Jingmen Petrochemical.
At present, all the inner components of large-diameter hydrogenation reactors in China are manufactured by our company. In 2002, we successfully produced the largest and the first in Asia diameter PX project isomerization reactor central tube and fan-shaped cylinder for Sinopec Zhenhai Refining and Chemical Company, replacing the imported ones and filling the blank in the production of Johnson nets for large-sized equipment in China; the inner components of the first coal-to-oil plant, Shenhua Group hydrogenation reforming and hydrogenation refining reactor, were manufactured by our company and put into use; the inner components of the largest diameter Ø4800 hydrogenation reactor of Sinopec Qingdao Refining and Chemical Company and others were also completed by our company. The inner components of large-diameter residue oil hydrogenation reactors in China were all manufactured by our company.
