Over the past decade, great progress has been made in chemical engineering and technology; truly, it’s a glorious era for China’s prosperity and strength! This post serves as a starting point for discussion—the more people participate, the livelier the conversation will be. With you here, Haichuan becomes even more wonderful! This is a continuously updated compilation post on “Ten Years of Great Development in Chemical Engineering Equipment”; everyone is welcome to join the discussion: https://bbs.hcbbs.com/thread-3576046-1-1.html. Let us enhance our awareness of quality and promote high-quality development. ----------------------------------------- On August 17, 2019, Sinopec launched a hydrogen injection process at its coal chemical division within Baling Petrochemical. This marked the implementation of one of the “Ten Key Projects” aimed at technological innovation; specifically, it involved an industrial demonstration plant capable of producing high-concentration hydrogen peroxide through the hydrogenation of anthraquinone in a slurry bed, with an annual production capacity of 20,000 tons. At 18:16 on August 23, the plant produced hydrogen peroxide of 28.1% concentration that met the required standards, marking the successful first operation of China’s first hydrogen peroxide production facility using the slurry-bed anthraquinone process, which features innovation and independent intellectual property rights. The successful commissioning of this demonstration unit has laid a solid foundation for the development of hydrogen peroxide production facilities to support the production of propylene oxide using caprolactam and hydrogen peroxide in Sinopec. The industrial demonstration project for producing 20,000 tons per year of high-concentration hydrogen peroxide via slurry-bed anthraquinone hydrogenation, carried out by Baling Petrochemical, was approved by Sinopec’s headquarters in 2015; it was included in Sinopec’s “Ten Dragon” scientific research projects in December 2016. This project was carried out jointly by Baling Petrochemical, the China Institute of Petroleum Science, Qingdao Safety Engineering Institute, Shanghai Engineering Company, Shijiazhuang Refining & Chemical Corporation, and Tianjin University. It aimed to develop China’s first green hydrogen peroxide production technology; the development was based on the second fixed-bed hydrogen peroxide production unit in Baling Petrochemical’s coal chemical division, with construction undertaken by Sinopec’s Tenth Construction Company. It is understood that the slurry-bed anthraquinone hydrogenation technology for producing high-concentration hydrogen peroxide represents the most advanced level of hydrogen peroxide production technology in the world today. Compared with traditional fixed-bed processes, this technology has four clear advantages: (1) increased production capacity; currently, the world’s largest slurry-bed hydrogen peroxide production facility has an annual capacity of 1.2 million tons, while China’s largest fixed-bed hydrogen peroxide production facility has an annual capacity of 400,000 tons ； (2) Improve the level of economic operation, with energy and material consumption dapat be reduced by about 20% ； (3) Improve environmental protection standards; wastewater discharge can be reduced by 30% ； (4) Improve the intrinsic safety level of the installation. In the previous process systems, there was a process of switching between acids and bases; hydrogen peroxide decomposes violently when it comes into contact with bases, which can lead to explosions. The new process system, however, remains in an environment of weak acids, ensuring that the production of hydrogen peroxide takes place under relatively stable conditions.
