The province plans to start with five key chemical industries. The fertilizer industry must adopt advanced coal gasification technology to strengthen the guidance of urea production in coke oven gas production and actively promote heat and power. Production, do a good job of recycling waste heat. Development of new ammonia synthesis towers and large-scale low-pressure synthesis of complete sets of technology and equipment, the use of urea modification technology, improve urea utilization.
The methanol industry should encourage the development of coke oven gas centralized processing methanol projects in concentrated areas of the coke industry, promote new coal gasification technologies and low-pressure synthesis processes in areas with low-quality inferior coal, build large-scale methanol production facilities, and simultaneously plan downstream deep processing projects. .
The calcium carbide acetylene industry needs to develop more than 25,000 kVA hermetic calcium carbide furnaces, promote the microcomputer control technology of calcium carbide furnaces, use new technologies of dust removal and exhaust gas utilization, recycle the powder and furnace gas heat energy, and promote the advanced energy-saving ion-exchange membrane caustic soda technology in the chlor-alkali industry; in the PVC industry Promote comprehensive utilization technologies such as large-capacity polymerization tanks and calcium carbide slag cement building materials.
Crude benzene processing and utilization industry should strengthen macro-control and industry management, prohibit the construction and phasing-out of existing acid cleaning benzene refining devices and processes, adopt advanced crude benzene hydrogenation refining process and crude benzene extraction refining process, improve crude benzene processing industry. The quality and benefits of development.
The coal tar processing and utilization industry should consider factors such as coking enterprise layout, total downstream product, resource utilization, process technology, and secondary product development. It is forbidden to construct coal tar processing equipment of 100,000 tons or less, and to encourage the use of a continuous distillation process to construct a single set of coal tar processing equipment with a processing capacity of 150,000 tons or more. Encourage secondary concentrated processing of coal tar processed products.
The “Eleventh Five-Year Plan†for Energy Major Provinces to Create Energy-saving Chemicals
In the five key coal chemical industries that process fertilizer, methanol, calcium carbide acetylene, crude benzene and coal tar, high-energy-consuming projects will be completely banned, and advanced coal chemical technology will be adopted and promoted. Saving energy and creating "energy-saving chemical industry" have become the theme of the "Eleventh Five-Year" development plan that Shanxi Chemical Industry has just completed.
