Qilu Petrochemical innovation drive "long-distance running"

As of June 23, the Acrylonitrile Plant of Qilu Petrochemical Acrylic Plant had a smooth “long-distance running” for 400 days, which not only extended the original operating cycle by 1 time, but also created the longest period of operation of domestic similar devices. This is the result of the dual innovation of management innovation and technological innovation of the plant.

Affected by the characteristics of the process, the 40,000 tons/year acrylonitrile plant of Qilu Petrochemical's acrylic fiber plant was forced to stop due to the polymer clogging pipeline and polymer accumulation in the tower every six months. Since May 19 last year, the plant has improved the performance assessment system for all employees. The factory and workshop have conducted comprehensive evaluation of the team and individuals from the completion of task indicators, democratic evaluation, and innovation capabilities. Those who have passed the assessment will be suspended from bonuses, which greatly mobilized the work enthusiasm of the staff. They extensively carried out the activities of “checking for hidden dangers, finding leaks, checking dead angles”, further optimized the operational indicators, and narrowed the control range of the technological indicators. In the past, the “zig-shaped” operating curve became a straight line and the polymer in the device was greatly reduced. . They also established a regular work schedule, held a device evaluation and analysis meeting once a week, monitored the status of important equipment from time to time, analyzed operating data and lubrication status, and found that abnormalities were dealt with in advance to ensure that the dynamic equipment was always in the best operating condition. The device is always in good standby.

Qilu Petrochemical Acrylic Fiber Factory has widely recruited innovative ideas among its employees and organized professional and technical personnel to tackle the problem, eliminating the obstacles to the safe operation of the device. The successful implementation of the proposal of “reducing the T-104 load” not only eliminated the obstacles that hampered the long-term operation of the device, but also achieved a reduction in output without reducing the output, and created an annual economic benefit of more than 1.2 million yuan. After the implementation of the rationalization proposal for “on-line cleanup of propylene and ammonia vaporizers”, the past practice of parking and cleaning up has become a thing of the past. "The reform of the medium-pressure steam control valve" completely solved the problem of unstable pressure in the medium-pressure steam pipe network by changing the air source signal of the control valve.
