In recent years, China Coal Group has made a breakthrough in large-scale coal chemical projects: it has completed the preparation of coal chemical development plans for three key coal chemical bases in Ordos, Inner Mongolia, Yulin, Shaanxi and Xinjiang; Three super-large coal chemical projects, namely, 3 million tons of dimethyl ether project in Erdos, Inner Mongolia, 2 million tons of synthetic ammonia/3.5 million tons of urea project in Erdos, and 3.6 million tons of methanol from Yuheng coal and its deep processing, have all entered the implementation stage; The preliminary work of the coal chemical project of Xinjiang Branch completed the feasibility review of the 4 billion cubic meters coal-to-natural gas project of China Coal Zhundong; The preliminary investigation and planning of Yili olefin project have been completed. China Coal Group will also invest in building an energy and chemical recycling green park in Shanxi.
Xu, assistant to the general manager of China Coal Group and head of the preparatory group for the coal chemical industry, said that while vigorously developing large-scale coal chemical projects with independent investment, China Coal Group is also actively trying cooperative development models. At present, it has signed joint venture cooperation agreements with Inner Mongolia Yuan Bo Group and Shaanxi Yanchang Group to realize cooperation, and acquired some existing coal chemical enterprises and coal chemical projects under construction.
Over the years, China Coal Group has attached great importance to technological innovation, especially technological breakthroughs in the field of new coal chemical industry. Xu said: "China Coal Group has achieved many technological breakthroughs. After many years of development experiments, a major breakthrough has been made in the international frontier technology field of low-carbon emission reduction-carbon dioxide reinjection and burial. On the basis of successfully injecting Shizhuang gas well in 2009 to increase the productivity by 50%, Zaoyuan gas well is currently being injected. The breakthrough and popularization of this technology can find a new way out for the large amount of carbon dioxide emissions of traditional enterprises at present; The project of manual extraction of methane gas by stripping method in methanol production of Longhua Company is the first in China, which has been completed and put into operation, achieving a production capacity of 654.38+0.2 billion cubic meters per year, directly improving the energy utilization rate and economic benefits; The group has mastered the technology of producing oil from coal and oil shale and made many innovations. At present, preparations are being made to build a 700,000-ton/year oil shale production project. In the aspect of deep processing and utilization of coal tar, through the technical research of producing light and heavy oil products from coal tar hydrogenation, a number of proprietary technical achievements have been obtained, and the processing capacity of 50,000 tons of medium oil per year has been realized, and the products are in short supply. By carrying out scientific research, development and practical activities in new technologies and fields, it has laid a good foundation for the development of coal chemical industry of the group company. At the same time, many efforts and attempts have been made in clean utilization of coal, energy saving and emission reduction, and the related work has achieved certain results: the coal-to-natural gas project of China Coal Longhua Company was completed and put into operation, and the daily gas supply to Harbin exceeded 654.38+10,000 cubic meters; Relying on 2.3 trillion cubic meters of coalbed methane resources, the formation of coalbed methane production capacity reached 330 million cubic meters/year. "
All this is inseparable from talent. Since 2009, China Coal Group has boldly practiced the talent construction mode, successfully introduced a high-quality and high-level coal chemical professional team, and initially formed a coal chemical production management and project construction management team with a certain scale and strength.
Xing Lei, an associate professor at China Coal Economic Research Institute of Central University of Finance and Economics, pointed out that from the perspective of industrial economy, coal chemical industry is an inevitable choice for large state-owned coal enterprises to develop from upstream industries to downstream industries. However, the whole industry needs a plan to avoid market risks and prevent excessive increase in production capacity. We should consider the requirements of energy conservation and emission reduction. Some coal chemical projects are heavily polluting and need to be cautious. In this regard, China Coal Group is ready.
In order to adapt to the trend of strategic adjustment of national energy structure, moderately develop new coal chemical industry, and rationally coordinate coal resources, water resources, ecological environment and other factors, China Coal Group has determined the general idea of coal chemical industry development in the next stage by drawing lessons from the experience of coal chemical demonstration projects and combining with the actual situation of enterprises. The development of coal chemical industry will adhere to the development of coal to olefins, actively develop new coal chemical industries such as coal to natural gas, optimize the development of coal coking, and moderately develop other characteristic coal chemical industries. Through the development of new coal chemical industry from a high starting point, the strategic adjustment of industrial structure of China Coal Group will be realized, and the coordinated development of coal and coal chemical industry will be promoted.
It is reported that the construction of the demonstration coal chemical base has started the preliminary work. According to the completed development plan of coal chemical industry in Erdos, Inner Mongolia and Yulin, Shaanxi, during 2009-2020, it is planned to complete the planned projects in stages by combining independent investment with cooperative projects. The total investment of the proposed coal-to-olefin and coal-to-natural gas projects in Yulin will exceed 654.38 billion yuan.
