[Ten years of development of chemical equipment] 640-2010 Daqing Petrochemical Company independently developed and manufactured hydrogenation reactors
Thread Content
Look at the great development of chemical equipment in the past ten years and praise the prosperity of China. Replies and prizes are welcome to discuss. ----------------------------------------------- On April 23, 2010, the R2101 hydrogenation reactor independently developed by China Petroleum Daqing Petrochemical Company was successfully put into hoisting and use, filling the technical gap of China National Petroleum Corporation. This hydrogenation reactor, independently developed and manufactured by Daqing Petrochemical Company, has a total weight of nearly 190 tons, a height of 22.7 meters, a diameter of 3.2 meters, and a service life of up to 20 years. It is the main core equipment of the 1.2 million-ton diesel hydrotreating unit of Daqing Petrochemical Refinery. The manufacturing process is complex, and in the past, this type of equipment was manufactured by equipment manufacturing companies outside the group company. During the design and development of the hydrogenation reactor, the R&D personnel of Daqing Petrochemical Machinery Plant searched for relevant information and specifically conducted welding process tests. Through actual operations, they explored reasonable parameters and overcame difficulties such as heavy equipment weight, special materials, and complex processes. They also solved many problems such as difficulty in determining welding process parameters, thus ensuring the quality of the main weld. The development of the hydrogenation reactor took one year and seven months. Its successful development marks that Daqing Petrochemical Company's equipment manufacturing industry has reached a new level in the field of heavy material equipment manufacturing.
Since the successful development of the first hydrogenation reactor in April 2010, Daqing Petrochemical has always been anchored at the forefront of the development of refining and chemical equipment manufacturing technology. Focusing on device production needs and user requirements, it has grasped the main line of technological innovation and concentrated on research. It has formed proprietary manufacturing technology and related inspection and testing methods. It has mastered and optimized barrel section forming, heat treatment, internal parts manufacturing and installation and other processes. It has designed adjustable preheating, head cladding clamping, machined grinding tools and other tooling equipment. In 2017, the hydrogenation reactor was listed as the group company's advantageous product and became a key product in the market development of Daqing Petrochemical's characteristic refining and chemical equipment. Currently, the product is used in the equipment production of Jilin Petrochemical, Ningxia Petrochemical and other enterprises, and all indicators meet or exceed the technical design requirements.

On July 13, 2021, Daqing Petrochemical Manufacturing completed three hydrogenation reactors for the 3 million tons/year naphtha hydrogenation unit of the Guangdong Petrochemical Refining and Chemical Integration Project and successively shipped them from the factory, setting a record for the container production line to support the manufacturing of multiple reactors at the same time. The three composite hydrogenation reactors have a total weight of 255 tons, each with a diameter of 4.4 meters and a main plate thickness of 74+3 mm. Compared with previous manufacturing, this kind of hydrogen-resistant steel composite layer material, large-diameter structure, and wall thickness are the first in the manufacturing of Daqing Petrochemical hydrogenation reactors, and require higher manufacturing technology such as forming, assembly, and welding. On the basis of absorbing the experience of manufacturing hydrogenation reactors, Daqing Petrochemical Machinery Factory optimizes technical processes, production organization, material procurement, etc. to improve the efficiency of production organization. During the manufacturing process, technicians and employees worked together to continuously solve many problems such as welding, assembly, one-time machining of large-diameter thick-walled bosses, and barrel section ovality control. Operators strictly implement technical processes, strictly control the manufacturing standards of each process, and promote production progress with stable quality.
The development of the hydrogenation reactor took one year and seven months.
