【Ten Years of Rapid Development in Chemical Equipment】Ester hydrogenation reactors and cyclohexane dehydrogenation reactors from 2010 to 2023

Thread Content

Ten years of rapid development in chemical technology – praise for China’s prosperity and strength. This is just a starting point; more participation from everyone will make things even more lively. Haichuan becomes even better with your involvement; we welcome everyone to take part more actively in the forum discussions. Be careful with fire risks as the heat increases in July. On July 5, 2023, the esterification process for the 600,000-ton per year caprolactam production facility within the Baling Petrochemical complex was successfully completed, and the facility has now entered the production preparation phase. “The \"200,000 tons per year cyclohexene esterification and hydrogenation to produce cyclohexanone\" integrated technology is one of Sinopec’s \"Ten Dragon\" scientific and technological development projects. It utilizes a new green production technique developed by Sinopec, featuring high carbon recovery rates, low emissions of waste substances, and being clean and efficient. It serves as an important technical foundation for the relocation, upgrading, and transformation of Baling Petrochemical’s industrial chain for the production of 600,000 tons per year of caprolactam. Lanshi Heavy Equipment developed 16 core units for this project, including ester hydrogenation reactors, cyclohexane dehydrogenation reactors, and light-end removal towers. Among them, the ester hydrogenation reactor utilizes the cyclohexane homologation technology pioneered by Sinopec, and is part of Sinopec’s initiative to achieve domestic production of key equipment. The R&D and Sales Center of Lanshi Heavy Equipment, in coordination with the Refining and Chemicals Branch and the Qingdao Company, carried out thorough preliminary technical preparations, strengthened overall coordination, adhered to the scheduled timelines, and organized production carefully, thus successfully completing the development of the products and delivering them on time. This provided strong support for the handover of the esterification cyclohexane unit in the Baling Petrochemical project.
