Red May for chemical industry workers! Reply reward! ---------------------------------------------- The past decade has been a period of rapid development for China’s chemical industry, with the emergence of many new processes, products, and equipment. China’s chemical processing equipment has also seen significant progress, which in turn has contributed to the swift advancement of the petrochemical sector. Here, we have compiled some of the achievements and breakthroughs made by Chinese equipment manufacturers in terms of larger-scale production and greater use of domestic equipment. We invite everyone to share, discuss, and exchange ideas – let’s cheer for Made in China and support the development of chemical processing equipment! ========================== @RedLee_ZZHI @WisdomBright @BookBoy @MightyUltraman. @As of the end of April, China’s first domestically produced boiling pump has been operating steadily for over 130 days in the liquid diesel cycle hydrogenation unit at the Dongxing branch of Sinopec Refining & Chemicals, enabling long-term operation and thus ensuring the safe production of the facility. The boiling pump is the core equipment in the fluidized bed hydrogenation technology and is a patented product. Boiling pumps imported from abroad are extremely expensive, have long delivery times, and are difficult to maintain. Therefore, developing domestic boiling pumps is of great significance in terms of reducing equipment costs, shortening delivery times, facilitating maintenance, and breaking through technical barriers. In April 2019, against this backdrop, the company, together with Sinopec Guangzhou Engineering Company and Hefei Huasheng Pump Valve Company, developed the first domestically produced boiling pump, which was successfully installed and put into use in the liquid-phase circulation hydrogenation unit at that facility in November 2020. The successful application of domestic boiling pumps has broken the long-standing foreign monopoly on this type of equipment. It is reported that the cost of these domestically produced boiling pumps is only 11% of that of imported pumps, **which reduces costs. Furthermore, according to the workshop supervisor, domestic boiling pumps feature full sealing for high safety, low space consumption, smooth operation, low noise, and no need for lubricating oil. They can effectively prevent leaks from mechanical dynamic seals, shorten the length of high-pressure pipelines and reduce the number of high-pressure valves, as well as address stress concentration issues in the pipelines at the pump’s inlet and outlet. This helps to significantly improve the safety level of operations.
