As of the morning of April 23, the gas-tight test of the depropanizer tower and the propylene tower of a 300,000-ton/year I gas fractionation unit of Anqing Petrochemical has reached 1.9 megapascals, and the deethanizer tower has reached 2.5 megapascals. If all goes well, The airtight tests of the three steel giants will end on April 24. At this point, the start of the device has entered a substantive stage.

With the completion of the renovation project of Anqing Petrochemical's 300,000-ton/year gas fractionation unit in the remote area and the completion of the project, the Department of Refining assumes the double responsibility of the safety production of each unit and the start of the new plant. Since the old I gas fractionation unit is currently under normal production, and the new I gas fractionation unit is under operation, the contradiction between the shortage of gas separation unit personnel is very prominent. In response, Refining One promoted the spirit of solidarity and collaboration, and deployed elite troops from catalysis, decompression, cracking, and other devices, and used the staff's large time to support the start of the gas separation plant.

After the new gas separation plant was handed over, the Department immediately flushed the device into water to remove system debris and open up the system piping to ensure the system was free. From April 21st on, the new air distribution unit began to enter the airtight experimental stage. All walks of life adhered to the site day and night, and gradually increased their pressure according to the operational requirements to check whether the valves, manhole welding, and installation were in good condition and eliminate the run in time. , take, drop, leak. Wang Yiting, a senior technician of the catalytic device, was on vacation. However, when he learned that the start-up of the new gas separation plant required human support, he volunteered and put in tight gas-tight experiments.

During the airtight process, some of the flanges were in a low position, and the airtight test was very difficult. Everyone climbed on the ground, kept changing observation angles, carefully checked and carefully checked; some of the flanges were in a high position and everyone contacted the equipment immediately. Technicians, scaffolding and then work hard. For several consecutive days, everyone reported the leaked items to the equipment technicians. After timely processing, the airtight inspections were conducted again to create favorable conditions for the start of the new gas separation plant.
