In the first quarter of this year, Dalian Petrochemical Company achieved a record high in the production of chemical products. The total volume of goods completed reached 81.963 million tons, an increase of 1.5226 million tons compared to the same period last year. This performance exceeded the planned target by 128.57%. Specifically, the company produced 81.254 million tons of polypropylene, up by 1.5052 million tons year-on-year. EPS (expandable polystyrene) output was 709 tons, rising by 174 tons from the previous year. Additionally, hexane production reached 2,496 tons, and the company reported a profit of 56.68 million yuan, reflecting strong operational progress.
To ensure smooth operations and avoid unplanned shutdowns, Dalian Petrochemical implemented the Group’s “Anti-violation Six Bans†policy. Employees were encouraged to identify potential hazards, while key equipment and critical areas received enhanced inspection and maintenance. In response to issues with the EPS production unit, technical teams proactively addressed challenges such as low production efficiency, high costs, pre-foaming, and inconsistent product quality. New temporary procedures were introduced to address emerging problems in the analysis of alkyl aluminum de-oiling in polypropylene plants. The use of propylene-enhancing additives significantly boosted liquefied gas yields across three catalytic units. Gas fractionation units also optimized their performance, overcoming challenges like poor cold-exchange efficiency and maximizing propylene output. In total, the company produced 72.28 million tons of propylene during the first quarter, while an additional 8,885 tons were sourced through outsourcing and mutual supply, ensuring a stable raw material supply.
The two polypropylene units operated under heavy load, focusing on energy conservation and cost reduction. Due to delays in the commissioning of two new 2,000mm propylene spheres, the company coordinated the operation of three catalytic units, gas fractionation systems, and two polypropylene lines to maintain material balance. This approach helped reduce fluctuations and streamline brand transitions. Dalian Petrochemical also participated in the China Petrochemical and Sales Company’s compliance initiatives, promoting energy-saving practices. After the anti-freezing period, the company promptly shut down steam and electric tracing systems, reducing energy consumption. Furthermore, it replaced imported catalysts with domestic alternatives, saving over 10 million yuan annually.
To maximize profitability, the company optimized its production processes and product structure. As a specialized chemical group, Dalian Petrochemical leveraged upstream and downstream relationships to improve overall efficiency. By aligning with the "production plan" and "scheduling scheduling" strategy, key devices were monitored closely, ensuring optimal performance. In the first quarter, the EPS unit produced 708.59 tons of EPS, with a yield of 86% for intermediate products, surpassing the historical high by 12%. During February, when severe ice and snow disasters disrupted land transport in southern regions, the company increased T36F polypropylene production from 5,000 to 9,000 tons, ultimately achieving 9,210.325 tons. This effort supported market stability and fulfilled social responsibilities.
Last year, the company produced 206,850 tons of polypropylene in the chemical segment, an increase of 9.2448 million tons year-on-year, with nearly 240 million yuan in profits. This year, Dalian Petrochemical aims to build on these achievements by leveraging its chemical sector strengths to achieve further improvements in all performance indicators. According to the schedule, two polypropylene units and the EPS facility will undergo major overhauls at the end of April, laying a solid foundation for future production expansion.
