Sino-Korea Petrochemical’s ethylene production increased by 24.36% on a year-on-year basis 2025-08-24 Since the beginning of this year, Sino-Korea Petrochemical has continued to optimize its production processes, achieving a series of breakthroughs in areas such as raw material selection, equipment maintenance, and technological innovation. By the end of July, its ethylene production had risen by 24.36% compared to the previous year, reaching a record high; this has provided a stable supply of raw materials for the regional petrochemical industry chain. In terms of raw material optimization, the company has successfully applied the new \"single storage and single processing\" process in the H-010 pyrolysis furnace, which greatly enhances the flexibility in selecting raw materials. This enables the facility to quickly adjust its production plans in response to market changes, effectively improving its ability to adapt to such changes and providing strong support for stable production. In terms of equipment maintenance, the company employed online replacement technology to successfully replace the two key heat exchangers, E-027 and E-501, without disrupting normal production. This approach resolved the issue of insufficient flow in the light hydrocarbons system, eliminated the bottleneck that prevented the plant from operating at full capacity, and significantly improved heat exchange efficiency, thereby removing obstacles to the plant’s full-scale operation. Progress in technical challenges has also been significant; they established a task force for pyrolysis quenching, and by implementing a biweekly meeting system, they regularly addressed production issues. It has successively overcome various technical challenges, such as the short operating cycle of the H-009 pyrolyzer and instrument failures in this pyrolyzer. In particular, when dealing with abnormal pressure at the venturi outlet, big data analysis was used to accurately identify the root cause of the problem, enabling rapid repairs and thus providing a solid technical foundation for the continuous and efficient operation of the facility.
