Recently, good news came from the chemical industrial zone: as of October 11, Daqing Petrochemical’s ethylene production for this year had exceeded 1.02 million tons. This marks the 10th consecutive year that the company’s ethylene production has exceeded one million tons. The path to success is never smooth. Behind this record lies the Petrochemical industry professionals’ determination to overcome technical barriers, their thorough efforts to optimize raw materials, and their relentless pursuit of excellence in management. Since the beginning of this year, Daqing Petrochemical has keenly recognized the value creation potential of ethylene production within the industrial chain. Guided by the goals of reducing carbon emissions and seizing opportunities for transformation and development, it has made stable and high-level ethylene production the \"engine\" for driving the company’s transformation and upgrading, as well as a \"link\" to promote the coordinated development of downstream industries. It continues to help downstream products in areas such as high-end materials and organic chemicals overcome technical barriers, systematically optimizing the product structure and thus laying a solid foundation for fostering new drivers of growth in the industry and capturing new opportunities in the high-end chemical sector. Meticulous operation and maintenance lay the foundation for long-term operation. The stable long-term operation of the equipment is a prerequisite for high ethylene production. Daqing Petrochemical ensures that its facilities are in optimal operating condition through precise maintenance and meticulous management. In April, during a partial maintenance period for the E2 unit, the company innovatively leveraged the process interconnections between the E1 and E2 units. By applying a dynamic switching technology for emission-free startup lines, it managed to carry out maintenance on the pyrolysis gas compressor without shutting it down, thus completing the maintenance tasks 9 hours ahead of schedule and to a high standard. To address the issues associated with equipment operation, the E2 unit adopts a customized backwashing strategy that effectively removes scale and impurities from the circulating water heat exchangers, resulting in a 14% increase in the flow rate of the propylene tower condenser. Through a series of measures, in the first 9 months, the company’s overall energy consumption for ethylene production decreased by 3.58% on a year-on-year basis, while the average operating cycle of the cracking furnaces in the E3 unit increased by 1.7% year-on-year, providing strong support for the sustained high and stable production of ethylene. At the same time, the capacity to supply raw materials along the downstream industrial chain has been strengthened, ensuring a steady supply of basic chemical raw materials such as ethylene and propylene to downstream facilities, which has significantly enhanced the overall resilience of the industrial chain. Optimizing resources to open up new avenues for cost reduction and efficiency improvement, Daqing Petrochemical thoroughly implements the concept of \"molecular refining,\" starting with optimizing raw materials in order to enhance the economic viability of ethylene production. By accurately identifying and reducing low-quality raw materials, high-quality resources such as hydrogenation tail oil are converted into feedstocks for ethylene production, enabling the daily output of hydrogenation tail oil to reach 1,200 tons. This has significantly reduced the proportion of high-aromatic components, further optimizing the structure of the ethylene feedstocks. We are actively promoting the transition of ethylene feedstock sources in the oil refining area toward higher quality materials. The catalytic dry gas C2 recovery unit has been successfully put into operation; it separates mixed hydrocarbons from catalytic cracking dry gas, thereby transforming hydrocarbon molecules that were previously regarded as low-value fuels into valuable ethylene-rich gas. In the first 9 months, this device has produced over 8,000 tons of ethylene-rich gas in total, helping to raise the daily ethylene production to more than 40 tons and achieving maximum utilization of resources while maximizing their value. On this basis, Daqing Petrochemical continues to improve the level of comprehensive resource utilization by allocating high-quality raw materials to the production of downstream high-value-added products, thereby effectively enhancing the overall competitiveness and risk resistance of its industrial chain. In the first 9 months, polyethylene resin production exceeded the planned target by 30,000 tons. Technology empowers and stimulates new drivers for endogenous growth. Technological innovation is the core driving force behind the high-quality development of enterprises. Daqing Petrochemical is intensifying efforts in tackling key technologies and promoting digital and intelligent applications, continuously infusing intelligent momentum into ethylene production. To address the issue of declining vacuum level in the rehydrator of the pyrolysis gas compressor, the QC team in the Ethylene Unit 1 pyrolysis plant overcame difficulties, developed a technology for online cleaning of the rehydrator, and effectively eliminated the bottleneck caused by high load operation of the plant. Transform process simulation software into a “superbrain” for production optimization. Continuously enhance technicians’ proficiency in operating and making in-depth use of this specialized software. Simulate product yields under various raw material compositions to achieve dynamic optimization of the production process and improve the operational efficiency of equipment. At the same time, opportunities in process simulation are widely collected and thoroughly explored to be transformed into specific plans for process optimization and equipment upgrades. In the first 9 months, the diene yield of the E3 unit increased by 0.13% on a year-on-year basis. It actively extends the outcomes of technological innovation to the lower stages of the industrial chain, and collaborates with external companies to develop acrylic products such as the \"Zhen Si\" series, which has attracted the attention of many high-end customers and provided strong impetus for the company’s transformation and upgrading.
