As of May 10, the 450,000-ton/year linear low-density polyethylene unit of Fushun Petrochemical Olefin Plant had achieved continuous and safe operation for 720 days, breaking the record of 569 days of safe operation for similar units of PetroChina, and achieved reduction in energy consumption, Production and efficiency goals.
In order to ensure the long-term operation of the device, Fushun Petrochemical organized technical backbones to conduct multi-party demonstrations based on the operating characteristics of the device, and introduced and implemented "four optimization" measures, namely optimizing real-time monitoring of raw materials, optimizing the operation of refining beds, optimizing the operation and monitoring of heat exchangers, Optimize the abnormal raw material screening plan. At the same time, Fushun Petrochemical has formulated a specific plan to optimize the real-time monitoring of raw materials, strengthen real-time monitoring and online precise monitoring, achieve regular sampling and analysis, and eliminate possible device fluctuations. Fushun Petrochemical has further strengthened the maintenance and maintenance of the online analysis instruments for raw materials, adding guarantee for the long-term operation of the device.
In order to avoid the failure of the fluidized bed reactor of the device and affect the long-term operation of the device, Fushun Petrochemical organized technical research to further optimize the polymerization reaction conditions and accurately control the height of the gas phase fluidized bed. By implementing a series of optimization measures, the accident was eliminated Risk is minimized.
Major unit is the key part of the device. Fushun Petrochemical started from strengthening the daily maintenance and management of the extruder system, continuing to do a good job in the daily maintenance of the circulating gas compressor, and doing a good job in the predictive maintenance of the discharge gas compressor and the nitrogen compressor, and implemented the management and maintenance of the unit to ensure the safe and stable operation of the device.
