Reporter learned yesterday from Tianjin Petrochemical, polypropylene, low density polyethylene, ethylene glycol, butadiene / MTBE, styrene and other five sets of equipment has completed the annual production plan ahead of schedule; as of December 31, the annual ethylene production will exceed 1,110,000 tons, refreshing historical records; and annual profit exceeded 5 billion yuan, the best since it was put into commercial operation.
Since the beginning of this year, Sinopec (Tianjin) Petrochemical Co., Ltd. has continued to optimize the structure of ethylene feedstocks on the basis of ensuring adequate supply of raw materials by Tianjin Petrochemical Company, timely import of overseas resources, supply of chemical raw materials and full operation of main equipment, achieving high and stable output and increasing output Efficiency.It is understood that Tianjin Petrochemical start from the strengthening of safety management, improve the safety awareness of all staff, emphasizing 'compaction of basic operations, strengthen emergency response and ensure stable production; deepen the environmental awareness, enhance technical skills, good staff reserve', vigorously carry out Basic skills training, while the process and fire drills normalized learning accident cases with the industry, with on-site management, HSE hidden dangers reported, special video seminars and other special training to enhance safety awareness and enhance emergency response skills to protect the safe operation of the device.
In view of the high turbine vibration of cracked gas compressor and the leakage of heat exchangers such as EA501 and EA204 which affect the safe and long-term operation of the plant, Tianjin Petrochemical Co., Ltd. focused its efforts on unit-specific maintenance and condition monitoring. , So that the risk of monitoring in the moment to ensure safe and stable operation of the device be reliably protected.
This year, the focus of Sinopec (Tianjin) Petrochemical Company started with the optimization of the firing and shutdown plans of pyrolyzers throughout the year and continuously optimized the shutdown plan for cracking furnaces. It completed the transformation of five low-NOx nozzles for cracking furnaces and two cracking furnaces The furnace tube renewal effectively reduced the number of unplanned shutdowns caused by the furnace tube leakage of the cracking furnace and laid the foundation for achieving the highest ethylene output in the whole year.
In addition, the stable operation of the device, based on the economic benefits of Tianjin Petrochemical instant optimization of product structure.It is understood that the relevant departments of the market-oriented, always concerned about the changes in market prices, based on the characteristics of raw materials, make full use of SPYRO (steam Thermal cracking simulation software) to fine-tune the depth of cracking, and optimize the product efficiency by using optimization tools such as APC (Advanced Process Control System).
