World’s heaviest hydrogenation reactor completed 2018-05-02 17:44 On April 28, a boiling-bed residue forge-welded hydrogenation reactor with an annual capacity of 2.6 million tons and a total weight of 2,400 tons was successfully manufactured by SINOMACH Heavy Equipment Zhenjiang Company. As the first fluidized-bed residue hydrogenation reactor in China’s refining sector, it has set two \"world records\" for hydrogenation reactors today: one is the \"world’s largest weight\" for such reactors – with a total length of over 70 meters, an outer diameter of 5.4 meters, and a weight of 2,400 tons ； Secondly, it boasts the highest complexity in manufacturing technology in the world; both its manufacturing processes and level of complexity exceed the global records for manufacturing hydrogen reactors. Not only that, but this hydrogenation reactor, developed by ERECO – a key manufacturing enterprise under SINOMACH Heavy Equipment Group Co., Ltd., which is part of China National Machinery Industry Corporation – is so large, heavy, and exceeds size limits that its transportation, lifting, and shipment set a new record for combined lifting operations in China; it is thus known as \"the biggest lift along the Yangtze River.\" To ensure the successful lifting and shipment this time, two 850-ton cranes and a 1600-ton self-propelled floating crane were used in combination for the lifting operation, setting a new record for the heaviest lift ever carried out on the Yangtze River waterway. In the 2.6 million tons/year upgrading project, the manufacturing of the core equipment, namely the fluidized bed residue forge-welded hydrogenation reactor, is crucial to the success of the entire project. When taking on this task, it was also the beginning of the period during which SINOMACH Group used its core business in heavy equipment manufacturing in China as a platform to build a leading enterprise in major equipment manufacturing in China and among the best in the world, one that integrated science, industry, and trade. On March 28, 2018, Sinomach Heavy Equipment, China’s first flagship enterprise integrating science, industry, trade, and manufacturing in the field of high-end heavy equipment, was officially established. The introduction of this \"national masterpiece\" – the fluidized bed residue forge-welded hydrogenation reactor – marks the first demonstration of the capabilities of SINOMACH Heavy Equipment. It is reported that, on the one hand, China National Heavy Machinery Corporation launched a large-scale collaborative manufacturing effort involving different specialties, systems, and regions, achieving remarkable feats in precision welding and assembly such as simultaneous manual welding of insert-type connections, \"horizontal\" assembly of distribution plates, as well as the fabrication of downcomers and nuclear source protection sleeves ； On the other hand, SINOMACH Group has integrated China National Heavy Machinery Research Institute and China National Heavy Machinery Corporation into ERIC’s core business, thereby completely addressing the issues of insufficient research, technological, and market capabilities at ERIC, and transforming it into a heavy machinery group capable of competing with the world’s strongest equipment manufacturing companies. With the advancement of institutional and mechanism reforms, the combined dual forces are prominently demonstrated in the manufacturing of fluidized bed residue forge-welded hydrogenation reactors. It is understood that the 2.6 million tons per year fluidized bed residue forge-welded hydrogenation reactor is a key piece of equipment in China’s projects aimed at improving the quality of petroleum products. Once completed and put into operation, this project will maximize the level of residue conversion, raising it to 85% (compared to only 40%–50% in the existing plant). At the same time, reducing the load on delayed coking and increasing the production capacity of light oils will enable China’s petroleum refining technologies to rank among the world’s most advanced, making them a truly vital asset for ensuring energy supply and building a beautiful China.
