The “Eleventh Five-Year Plan†for Energy Major Provinces to Create Energy-saving Chemicals
In the five key coal chemical industries—fertilizer, methanol, calcium carbide and acetylene, crude benzene, and coal tar—high-energy-consuming projects will be strictly prohibited. The focus will shift toward adopting advanced technologies to create an energy-efficient chemical industry. This transition is a central goal of Shanxi Chemical Industry's recent "Eleventh Five-Year" development plan, emphasizing energy conservation and sustainable growth.
The province has set clear priorities for each of these sectors. In the fertilizer industry, advanced coal gasification technology will be introduced to improve efficiency in urea production using coke oven gas. The initiative also includes promoting combined heat and power systems, optimizing waste heat recovery, and developing new ammonia synthesis towers and large-scale low-pressure synthesis technologies. Urea modification techniques will further enhance production efficiency and resource utilization.
For the methanol industry, the plan encourages centralized processing of coke oven gas in regions with high concentrations of coking activities. New coal gasification technologies and low-pressure synthesis methods will be promoted, especially in areas where low-quality coal is abundant. Large-scale methanol facilities will be developed alongside downstream deep-processing projects to maximize value.
In the calcium carbide and acetylene sector, the goal is to build more than 25,000 kVA hermetic calcium carbide furnaces and implement microcomputer control systems. Dust removal and exhaust gas utilization technologies will be adopted, along with heat recovery from powder and furnace gas. Advanced energy-saving ion-exchange membrane caustic soda technology will be promoted in the chlor-alkali industry, while the PVC industry will benefit from comprehensive utilization technologies such as large polymerization tanks and cement materials made from calcium carbide slag.
The crude benzene industry will see stronger regulatory oversight, with a ban on outdated acid cleaning refining processes. Instead, advanced hydrogenation and extraction refining methods will be implemented to improve quality and profitability. For coal tar processing, the focus is on layout optimization, resource efficiency, and secondary product development. Projects with a capacity of less than 100,000 tons will be prohibited, while larger continuous distillation units with a capacity of over 150,000 tons will be encouraged. Secondary processing of coal tar products will also be supported to increase overall value.
