The output of various chemical products reached a record high!

The reporter learned from Sichuan Petrochemical that the company has continued its efficient and stable operation since 2024. Since the beginning of this year, the ethylene yield has increased by 0.63% and the diene yield has increased by 1.25%. It is worth noting that in 2024, the company's ethylene output reached 890,000 tons, breaking the record, and the output of polyolefin, cis-butadiene rubber, butyl octanol and other products all reached record highs.

Sichuan Petrochemical Company fully optimized raw materials and indicators, optimized operation, improved management, implemented "one device, one policy", solidly promoted the special action of improving quality and increasing efficiency, and comprehensively promoted the "stable, long and excellent" operation of the enterprise.

Optimize raw materials and indicators for development. The company promoted the integration of production and learning, and carried out in-depth cooperation with Lanzhou Chemical Research Center of Petrochemical Institute to calibrate and evaluate cracking raw materials and cracking products. Daily use of optimization simulation software to guide the improvement of production efficiency, according to the composition of raw materials and analysis conclusions, according to the concept of "olefin is olefin", the key indicators such as cracking depth, dilution steam ratio and cracking temperature are optimized to effectively improve the yield of target products.

Optimize operation to help smooth operation. The company pays close attention to the key indicators and key links of the device to ensure the efficient operation of the production device. Optimize the operation of "twin towers" in ethylene plant, deal with seasonal extreme weather in time, and adjust production according to the time by effective measures such as heat exchanger backwashing. Aiming at the key core parts such as cracking furnace and compressor, a research team was set up, a special care plan was formulated, and the special care management was carried out in the mode of daily report, weekly meeting and monthly summary. The key parameters such as vibration of large unit and COT of cracking furnace are monitored and recorded in all directions and all time, and the reasons for the deviation are analyzed and adjusted in time, which lays the foundation for the high-load operation of ethylene plant. In 2024, the cumulative energy consumption of ethylene decreased by 48.192 kg standard oil/ton year-on-year, realizing the maximization of economic benefits.

Promoting management to increase the power for enterprise development. Sichuan Petrochemical Company has implemented the working mode of "weekly analysis, weekly summary and weekly plan" closely around the management idea of strengthening management and creating the first class, and evaluated the weekly work from four aspects: production, equipment, safety and team. The production department insists on holding a weekly "three-machine" operation state analysis meeting to evaluate the unit operation parameters and sampling analysis results and formulate practical measures to ensure the long-term stable operation of the unit. The company strives to push the management mode from refined to lean, constantly explore the optimal operation state of equipment under various working conditions, dig deep into the potential of the equipment, strictly implement the requirements for the investigation of hidden dangers in production safety, focus on the key indicators of production safety, mobilize all staff to participate in the investigation of hidden dangers, fully realize the front-end planning and management, and provide effective guarantee for the high-load operation of ethylene plants.

At present, Sichuan Petrochemical Company's complete set of production equipment is starting full-load operation mode, laying a good foundation for achieving a good start in 2025.
