Coal chemical industry includes traditional coal chemical products such as coke, synthetic ammonia, calcium carbide, and methanol, as well as modern coal chemical products such as coal oil, olefins, dimethyl ether, and methane gas. At present, the traditional coal chemical industry has entered a mature period, and the main product production capacity has been surplus; modern coal chemical industry has just started and is still in the demonstration stage.
With regard to the traditional coal chemical products that have excess production capacity and are still developing blindly in local areas, it is necessary to resolutely curb the blind development momentum and increase structural adjustment, reduce production costs, and increase product competitiveness on the basis of total control.
Specific measures: First, strict project approval management, and the approval of coke, calcium carbide, methanol, and other coal chemical projects that simply increase production capacity in the next three years, and investment control departments at all levels for projects that do not meet the requirements for adjustment and revitalization of key industries and industrial policies. Not approved or filed.
The second is to strengthen the access management, the new coking unit must reach the height of the top-mounted coke oven carbonization chamber ≥ 6.0 meters, the height of the ramming coke oven carbonization chamber ≥ 5.5 meters; the new calcium carbide device must use closed or internal combustion type calcium carbide furnace, single Furnace capacity should not be lower than 25000KVA; Newly-built ammonia plant with a scale of less than 300,000 tons/year, which can not reach the access standard for synthetic ammonia energy consumption; New coal-to-methanol plant with a scale of less than 1 million tons/year is forbidden.
Third, speed up the elimination of outdated production capacity, use market competition mechanisms, improve access conditions, implement differential electricity prices, and strengthen safety and environmental protection supervision and other administrative measures to accelerate the elimination of outdated production capacity that does not meet entry standards and poor market competitiveness.
Modern coal chemical industry is mainly an oil substitute product. China’s petroleum resources are in short supply. In 2008, foreign dependence was as high as 51%. China’s coal resources are relatively abundant. The use of abundant coal resources and the development of coal-based petroleum substitute products are necessary for enhancing the safety guarantee capability of petroleum. . However, modern coal chemical projects have high investment, complicated technology, occupy large amounts of environmental capacity, coal and water resources, and the product competitiveness is greatly affected by the energy ratio, and there are certain economic risks. Therefore, we should make careful decisions and develop steadily. At present, the state-approved coal-to-oil demonstration project is in the trial production stage, and the demonstration projects for coal-to-olefins, dimethyl ether, and methane gas are still under construction or in the early stage of work. The current main task is to do a good job of the above-mentioned project demonstration work. Before the success of the project, it is not appropriate to build a large-scale modern coal chemical plant. In order to stop the blind development of modern coal chemical industry, the “Several Opinions†proposed that no new coal chemical pilot project be arranged in principle in the next three years. After the successful demonstration project, we will coordinate the supply of coal resources, ecological and environmental protection, product market demand, and steadily promote the development of modern coal chemical industry.
