Since 2023, Sinopec Jiujiang Petrochemical Co., Ltd. has continued to tackle difficulties and create benefits, and carried out equipment condition optimization and technical research. As of August 24, the gasification furnace C of the coal-to-hydrogen plant has been running safely and smoothly for 158 consecutive days, setting a new record at home and abroad Operation record of single burner gasifier.
This record means that Sinopec has set a long-term benchmark for the domestic and foreign coal-water slurry industry, which is of great significance for promoting the manufacturing improvement of the core equipment burners of gasifiers and consolidating the long-term operation of gasifiers in the industry. This not only improves the overall operation control capability of the device, but also reduces energy consumption. Coal consumption per ton of hydrogen and total energy consumption are reduced by 2.4% and 1.6% respectively, and more than 2 times of furnace downtime during the year are reduced, which effectively reduces safety risks. Compared with 100 days Counting the downturn cycle, the annual cost saving is more than 6 million yuan.
Safety is a top priority for long-term operations. The C series of four coal-to-hydrogen units operated by Jiujiang Petrochemical Co., Ltd. were put into operation on March 19. During this period, they experienced extreme weather such as heavy rain and intense heat. In order to ensure the stable operation of the C series gasifiers, Jiujiang Petrochemical, relying on Pang Gang’s innovation studio, organized discussions on the long-term operation of gasifiers for many times, formulated the "Gasifier Long-term Operation Management and Control Plan", and formulated targeted control measures. Check the form of the weekly post inspection report to supervise the implementation. Party members actively take the lead in checking hidden dangers to ensure safety and ensure continuous and stable hydrogen supply.
Long run times mean more uncertainty. To this end, Jiujiang Petrochemical actively summed up the previous long-term operation experience, constantly figured out and understood the "temper" of the device, and carried out production research on weak links, optimized adjustments and fine operations, and solved the problem of gasifier synthesis gas outlet pressure. A series of bottlenecks such as large difference, clogging of Venturi scrubber, poor heat transfer effect of high-flash heat exchanger, etc., the gasifier has been operating stably. After breaking through the 151-day operation record of a single-burner gasifier of a similar plant in Sinopec at the beginning of the year, it has been continuously refreshed Running record.
