The update and renovation of outdated equipment in chemical enterprises are a critical measure to strengthen the bottom line of production safety. In recent years, Huai'an City has systematically advanced the update and renovation efforts across its chemical industry, effectively tightening the "safety valve" to support high-quality industrial development. As of now, all 34 outdated equipment units across 19 enterprises identified in the city's 2023-2024 inspections have been fully replaced, while 22 units from 17 enterprises identified for 2025 are currently under renovation. These efforts have driven over RMB 450 million in enterprise investment. In 2023, the city secured RMB 11.11 million in provincial renovation subsidies, and funding support for 2024 and 2025 is currently under application.

In 2023, all 14 equipment units across 9 enterprises were updated and renovated on schedule. Among them, the air separation unit project of Yingde Gases from Jiangsu received a provincial subsidy of RMB 9.1479 million, accounting for 82% of Huai'an's total provincial subsidy that year, making it a benchmark project. In 2024, enterprises independently invested RMB 48.65 million to complete the renovation of 20 equipment units. A number of high-risk devices, such as the molten granulation tower of Jiangsu Lanpeng Fertilizer Co., Ltd. and the distillation tower of Jiangsu Yongchuang Pharmaceutical Technology Co., Ltd., have been replaced with intelligent equipment, significantly improving the level of intrinsic safety. For 2025, the Huai'an Emergency Management Bureau has established a "weekly scheduling and monthly inspection" mechanism to guide enterprises in formulating detailed implementation plans covering equipment procurement, construction progress, and risk control. To date, on-site inspections have been conducted on six completed units to ensure both renovation quality and safety compliance. A total investment of RMB 100.234 million is planned for the year, including RMB 55 million for a single project—the 300,000-ton/year hydrogen peroxide unit of Jiangsu Fuqiang New Materials Co., Ltd.—which is expected to serve as a model for intelligent upgrades.
