As of the morning of April 23, the gas-tight testing of the depropanizer and propylene towers in Anqing Petrochemical’s 300,000-ton-per-year I gas fractionation unit has reached 1.9 megapascals, while the deethanizer tower has successfully achieved 2.5 megapascals. If everything proceeds smoothly, the airtight tests for all three major towers are expected to be completed by April 24. This marks a significant milestone, as the plant startup is now entering its critical phase.
With the completion of the remote-area renovation project for the 300,000-ton/year gas fractionation unit, the Refining Department now faces the dual challenge of ensuring safety across all units and managing the startup of the new facility. Due to the ongoing operations of the old I gas fractionation unit and the simultaneous start-up of the new one, there has been a noticeable shortage of personnel in the gas separation area. To address this, Refining One mobilized teams from various departments, including catalysis, decompression, and cracking, and deployed experienced staff to support the startup process.
After the new gas separation plant was handed over, the department immediately began flushing the system with water to remove debris and prepare the piping for operation. Starting from April 21, the air distribution unit entered the airtight testing phase. Teams worked around the clock, gradually increasing pressure according to operational standards to check valves, manholes, and welds for leaks. Any issues were promptly identified and fixed.
Wang Yiting, a senior technician from the catalytic unit, had planned to take a vacation but quickly returned when he learned that the new plant required additional support. He joined the airtight testing team and contributed significantly to the effort.
During the airtight test, some flanges were located in hard-to-reach positions. For low-position flanges, workers crawled on the ground, changing angles to inspect thoroughly. For high-position flanges, scaffolding was set up, and technicians climbed up to conduct inspections. Over several consecutive days, workers reported any leaks to the equipment technicians, who then addressed the issues. After repairs, re-tests were conducted to ensure the system was ready for full operation.
This collaborative effort has created a solid foundation for the successful startup of the new gas separation plant. The dedication and teamwork displayed by the staff have played a crucial role in overcoming the challenges faced during this critical phase.
