Coal slime dryers add fuel to the development of coal chemical industry
The development of coal chemical industry in the future is bound to be a trend. Coal slime dryers will treat coal slime materials after coal washing, which can add support to the development of coal chemical industry. For a long period of time now and in the future, China’s modern coal chemical industry should adhere to the development principles of layout science, technology leadership, high efficiency, clean and low carbon, and orderly development, and break through a batch of key core technologies with independent intellectual property rights. We will build a batch of demonstration projects that can be replicated and promoted to form a batch of large-scale enterprises and enterprise groups with international competitiveness, and create a large number of large-scale industrial bases with rational layout and eco-friendliness.
According to the country's main functional area planning and the distribution of 13 large coal bases, comprehensively consider the environmental capacity, resource carrying capacity, market demand and transportation conditions, and reasonably plan coal chemical demonstration projects. From the aspect of enterprise scale, technology level, energy consumption, environmental protection, safe production, and resource conditions, we will study and formulate strict admission standards, control total production capacity, suppress overheated investment, and eliminate disorderly development.
The areas where the conditions are available can actively promote the co-production of coal chemical and power, metallurgy, cement, calcium carbide, coking, petrochemical, and wind energy industries, and build an ultra-large, cyclical, multi-generation modern coal chemical comprehensive industrial cluster. Enterprises can couple and integrate a number of coal chemical technologies, promote the recycling of links between different industries, produce a variety of clean fuels, chemical raw materials, and hot products, significantly increasing the overall utilization of resources.
It is understood that an annual output of 4 billion cubic meters of coal gas projects, the investment amounted to 26 billion -30 billion yuan, half of which are concentrated in the field of coal chemical equipment manufacturing, equipment purchase costs far exceeds the construction, installation, design management, Construction period interest and other expenses. According to forecasts, the average annual compound annual growth rate of equipment demand will be above 40% in 2017. Therefore, as the largest investment link in the industrial chain of coal chemical projects, the slime dryer equipment manufacturing industry will usher in a golden period of development.
It is reported that gasifiers and air separation plants are the two core equipment for coal chemical projects. In May, the former chief engineer of the China Federation of Machinery Industry Yan Yongbin emphasized at the Fourth China Petroleum Equipment Procurement International Summit and Exhibition that although the localization of relevant coal chemical equipment has achieved certain results, it must not be ignored that the level of autonomy is still poor. fact. In this regard, experts said that although China's gasifiers and air separation equipment have localized performance, many key components, especially large and extra large air distribution units, superchargers, oxygen breakthrough, nitrogen breakthrough, and Pressure expansion machines, full-liquid high-pressure expanders, high-pressure cryogenic liquid oxygen, liquid nitrogen and hydraulic pumps and other machinery and equipment, high-pressure cryogenic valves, control systems, etc., poor safety and reliability, low operating efficiency, high energy consumption, so project owners worry about The quality is not reliable, even if the domestic equipment is cheap, it must be imported from abroad at a high price.
In addition, compared with the traditional coal chemical equipment, the new coal chemical equipment is more difficult to develop and requires higher precision. Many key technical issues need to be solved in all aspects of manufacturing, welding, transportation and installation. Experts in the industry also emphasized that both traditional coal chemical and new coal chemical projects are high energy-consuming, high water-consuming, and highly polluting industries. Therefore, to promote the development of coal-to-oil and coal gas production, we must adhere to clean and efficient conversion. In the development of equipment, we must strictly implement the principles of water conservation, environmental protection, and cleanliness, and conduct technological research and development to build high-end upgraded version of new coal chemical equipment. Therefore, for coal chemical equipment manufacturing companies, not only must we overcome difficulties in technology, but also focus on product quality, and focus on developing energy-saving and environmental protection in the production process.
