As a key equipment for refining, hydrogenation reactors are regarded as a symbol of the manufacturing capacity of refining equipment with a complex manufacturing process and many core technical difficulties. This plate-welded hydrogenation reactor was started from the evaluation of the welding process in October 2008 and the work time was 1 year and 7 months. Since the operation of the 1.2 million-ton/year diesel hydrorefining unit at the Daqing Petrochemical Company's refinery in September 2010, the indicators have been normal and the equipment is in good condition, fully satisfying the operating requirements of the equipment.
The R2101 plate welding hydrogenation reactor manufactured by Daqing Petrochemical is the main equipment of the 1.2 million tonne/year diesel hydrotreating unit. The design pressure is 8.6MPa and the design temperature is 450°C. It belongs to high temperature and high pressure equipment and must be selected for high temperature and strength. The heat-resistant steel serves as the outer wall material. To this end, Daqing Petrochemical Machinery Factory R & D personnel to find relevant information, specifically for welding process tests, through practical operation, find reasonable parameters, to overcome the equipment weight, special materials, complex processes and other difficulties, to solve the welding process parameters to determine And many other problems have ensured the weld quality of the main equipment. In the hydrogenation reactor manufacturing process, seven key technologies, including electrodepositing, support ring surfacing, and narrow-gap submerged arc welding, were used. The reactor weighs nearly 190 tons, is 22.7 meters high and has a diameter of 3.2 meters. Its service life is at least 20 years.
Daqing Petrochemical independently manufactures hydrogenation reactor
On November 25th, the plate-welding hydrogenation reactor independently developed by Daqing Petrochemical Company Machinery Plant passed the review of the expert group organized by China Petroleum Refining and Chemicals Branch.
