Coal Chemical Industry Development Needs Advanced Technology Guarantee
In response to concerns about overinvestment and redundant construction in China's coal chemical industry, Wei Gong, chairman of the Taiyuan Chemical Industry Group, emphasized that Shanxi's coal chemical sector should focus on energy conservation and technological advancement during the "11th Five-Year Plan" period. He pointed out that most current projects are concentrated in areas like coal-to-oil and coal-to-methanol, lacking distinctive products and suffering from serious duplication at a low level. If these large-scale projects are completed, they will lead to a sharp rise in similar product outputs, potentially causing oversupply, falling prices, and corporate losses, as seen in past cycles of domestic overbuilding.
According to the national coal industry’s "Eleventh Five-Year Plan," total coal used for chemical purposes is expected to reach only 100 million tons by 2010. For Shanxi, which relies heavily on traditional coal chemical industries, this presents an even greater challenge. To accelerate its chemical industry development, the province must shift toward building an "energy-saving chemical industry."
Moreover, a science and technology-driven strategy must be implemented, with targeted planning. For example, in the methanol sector, efforts should be made to promote centralized processing of coke oven gas for methanol production in regions where coking is concentrated. New coal gasification technologies and low-pressure synthesis processes should be encouraged in areas with low-cost, low-quality coal, while large-scale methanol facilities should be developed alongside downstream deep-processing projects.
In the fertilizer industry, advanced coal gasification techniques should be adopted, and guidance for urea production using coke oven gas should be strengthened. Cogeneration should be actively promoted, and waste heat recovery should be optimized. The development of new ammonia synthesis towers and large-scale low-pressure synthesis equipment, along with the use of modified urea technology, can improve urea utilization and maintain competitive advantages. By focusing on innovation and efficiency, the industry can better navigate the challenges ahead.
