【Ten Years of Rapid Development in Chemical Processing Equipment】970–2021: Acceleration toward domestic production of high-temperature and high-pressure forced-circulation hot water pumps for heavy-duty units
Thread Content
Ten years of rapid development in chemical processing equipment; praise for the prosperous and strong China. This is just a starting point to encourage more people to get involved, making things even more lively. Haichuan becomes even better with your participation – we welcome everyone to join in the forum discussions. Everyone should focus on safety and know how to handle emergencies. ********************************************* In July 2021, the circulation pump – a high-temperature, high-pressure forced circulation hot water pump used in the waste heat boiler systems of heavy catalytic units – was developed independently by Shengli Pump Co., Ltd. under SHENGU Group, marking the achievement of domestic production of such pumps. In 2017, at the request of its client Jingmen Petrochemical, Shengli Pump Group’s Petrochemical Pump Company was responsible for the design of the pump’s structural components, hydraulic systems, auxiliary systems, and instrument control; it worked together with a design institute to develop this equipment. It is understood that this set of equipment was independently developed by the Petrochemical Pump Company based on the technology of subcritical boiler water circulation pumps. After three years of effort, in May 2020, this device was granted a **utility model patent**. The first set of such devices was put into use in June of the same year. Once it began operating successfully, the device showed stable performance in terms of all relevant parameters, with its technical specifications reaching advanced levels comparable to those of international counterparts. This breakthrough broke the foreign technological monopoly and filled the gap in technology and application in this field in China, providing new solutions for the water circulation systems in waste heat boilers used in similar oil refining and steel manufacturing plants both domestically and internationally. It is understood that a large-scale heavy oil catalytic cracking unit requires 6 forced circulation hot water pumps. The price of imported products is approximately 6 million yuan per set; once this unit is developed, the expected price per set will be 3.1 million yuan, resulting in savings of 2.9 million yuan in equipment acquisition costs, which represents significant economic benefits. The delivery time for the complete unit can be reduced by 4–6 months compared to imported products, avoiding issues such as long procurement and supply cycles for imported components, high costs, and monopolistic practices, thereby ensuring the safe and efficient operation of the equipment and the refinery.
On December 30, 2020, Jingmen Petrochemical’s 2.8 million tons per year heavy oil catalytic cracking unit held a handover confirmation meeting on site, officially entering the handover phase. Representatives from the participating companies SEI and SNEI, the supervision party, and relevant parties from Jingmen Petrochemical attended the meeting. The 2.8 million tons per year heavy oil catalytic cracking unit is one of Sinopec’s \"Ten Dragon\" key project initiatives, with a total investment of 1.188 billion yuan. The project employs advanced technologies such as the MIP process, heterogeneous mixing and emulsification of feed oil, high-efficiency feeding nozzles and atomization techniques, as well as combined flue gas purification systems. Once completed, it will address issues such as the company’s insufficient catalytic processing capacity, difficulties in balancing heavy oils, the inability to fully utilize the benefits of residue hydrogenation, challenges in adapting the lubricant production system to market changes, and the need to improve the company’s environmental protection and quality standards. It is expected to generate approximately 36 million yuan in profits per month after it goes into operation. As an EPC project, since its commencement, Jingmen Petrochemical’s Party and administrative leadership have attached great importance to it. All parties involved in the project, together with Jingmen Petrochemical’s key project department, overcame various difficulties such as staffing issues, weather conditions, and funding constraints. Through coordinated management and meticulous organization, and with the full support and cooperation of all parties, the project was completed on schedule. In the next phase, all parties involved in the project will take the completion of the unit construction as a new starting point, intensify the coordinated efforts related to the final adjustments and commissioning trials, strictly adhere to safety standards, and ensure rigorous quality control, so as to guarantee the successful first-time operation of the 2.8 million tons per year heavy oil catalytic cracking unit.
