Abstract: Hydrogenation reactor has been used widely as the core static equipment of hydrogenation unit and there is a need for more than a dozen of new hydrogenation devices or expansion upgrading devices in CNPC petrochemical enterprises per year. In order to enhance the equipment manufacturing capacity of CNPC and break the external procurement status, PetroChina Daqing Petrochemical Company has carried out the research on such equipment manufacturing business, and mastered a set of core manufacturing technology successfully, including narrow gap automatic welding technology, buttering technique with electrode, TIG automatic welding for small pipe and so on. At the same time, the advanced TOFD nondestructive testing technology, electron accelerator detection and acoustic emission detection technology have been used for detecting equipment and the results are satisfactory. Upgrading and reforming the hydrogenation refining unit of 1. 2 million tons/ year and the national V grade oil unit, 3 sets of plate welded hydrogenation reactors for 1. 3 million tons of diesel hydrogenation and desulfurization devices are all finished, and put into industrial application. These new devices are advanced and reliable, and featured with strong innovation and good effect of industrial application. Its successful application showed that the Group Company’s equipment manufacturing technology has reached the international advanced level.
