Jiujiang Petrochemical Sets New Record for Single Burner Operation of Gasifier Author/Source: Sinochem News Network Date: February 23, 2023 Clicks: 23 China Petrochemical’s Jiujiang Petrochemical Company has continued to work on optimizing the operational conditions of its facilities and advancing technological innovations. As of 12:00 on February 21 this year, Gasifier A of the coal-to-hydrogen plant operated by Unit 4 at Jiujiang Petrochemical had been running safely and steadily for 181 days. This marks another update to the record for single burner operation of gasifiers, both domestically and internationally, following the 158-day record set in 2022. This marks Sinopec’s establishment of a long-term benchmark for the water-coal slurry industry both domestically and internationally, and it is of great significance for ensuring the long-term operation of gasifiers in this industry. For enterprises, this not only improves the overall operational control capabilities of the equipment and reduces energy consumption, but also effectively decreases the number of times the furnace needs to be shut down, thereby lowering safety risks. It is reported that Gasification Unit A of this coal-to-hydrogen plant began operating with feedstock processing on August 24, facing extreme weather conditions such as persistent high temperatures and heatwaves, as well as severe cold during that period. To ensure the stable operation of the gasification furnace, Jiujiang Petrochemical, relying on the Pang Gang Innovation Studio, has organized numerous discussions on its long-term operation, formulated a \"Control Plan for Ultra-Long-Term Operation of the Gasification Furnace,\" and developed targeted control measures to strengthen process operation management. Progress is monitored through daily inspections and weekly reports; equipment inspections and preventive maintenance are intensified to maintain optimal operating conditions of the equipment. The use of \"two types of records\" is enhanced, strict safety controls are applied during the construction of the gasification furnace, and a closed-loop management system is implemented for addressing issues on-site. Party members take the lead in identifying potential hazards to ensure safety and maintain a continuous and stable hydrogen supply. Especially at the turn of the year, a large number of employees contracted the COVID-19 virus. On the one hand, the team members of Pang Gang’s Innovation Studio conducted thorough discussions regarding the situation at the time, assessed the operation of Furnace A, and took into account previous experience with long-term operations in order to establish new operational goals for the gasification furnace. On the other hand, the four management staff members took proactive actions and stepped in promptly to ensure that there were sufficient safety personnel on duty. Daily inspections at both the professional level and at the team level were carried out on key areas as well as equipment such as the wall temperature of the gasification furnace, to ensure the proper operation of these critical devices. By closely monitoring changes in various indicators and making precise adjustments, it was possible to effectively control challenges such as the pressure difference at the syngas outlet of the gasification furnace and the heat exchange efficiency of the high-flash heat exchanger. This allowed the plant to withstand the impacts of the pandemic and maintain safe and stable production. The maximum operating cycle for a single furnace in the coal-to-hydrogen plant continued to set new records, rising from 130 days to 151 days, then to 158 days, and finally reaching a new high of 181 days.
