After nearly 30 hours of strenuous efforts to repair, on May 13th, Yangzi Petrochemical's olefin plant successfully eliminated the potential leakage of the ethylene refrigerant EA-502C propylene refrigerant cooler and ensured the safe operation of the ethylene plant. At present, the cooler is in good condition. In the recent search for hidden dangers, employees in olefin plants have found that there has been a gradual increase in the viscosity of second-phase devices. After multiple investigations, it was confirmed that ethylene equipment EA-502C was leaking into the circulating water in the tube due to leakage of the tube. Due to the propylene material inside the cooler and the pressure is too high, plugging cannot be cut out. Therefore, on the one hand, the olefin plant has taken special measures such as strengthening monitoring and increasing the amount of water supply; on the other hand, it has communicated with the relevant departments of the company in a timely manner to study solutions for hidden dangers. After repeated argumentation and multiple revisions, the olefin plant has developed a detailed and detailed EA502C on-line culling program and a defect-free HSE program. It also identifies operational hazards and risk assessment for deficiencies, and lists HSE risk control measures and emergency measures in detail during the operation process. . On May 10th, the olefin plant organized an elite soldier. After the cooler was cut out, it began repair work for two days and one night. The maintenance personnel strictly implemented each step of the plan and closely supervised the construction safety precautions. After nearly 30 hours of hard work, the ethylene device EA-502C propylene refrigerant cooler was successfully plugged. 8 Mm Thickness Wall Panels,Eco Friendly Wpc Wall Panel,Eco Friendly Wpc Wall Sheet,Wpc Exported Wall Panel Decoration Puyang Shangyi Decoration Material Co., Ltd. , https://www.pysydecoration.com
