Transformation and upgrading of coal chemical industry in Western China

wallpapers News 2020-11-30

the national development Reform Commission officially issued the "catalogue of encouraged industries in Western China" which will be implemented from October 1. Compared with the previous draft, coal to olefin coal to methanol projects in Xinjiang, Inner Mongolia, Ningxia, Shaanxi, Gansu other places have been won. The reporter learned in an interview a few days ago that this adjustment has released the signal of cooling down the investment in coal chemical industry. However, there is still a large space for the development of coal chemical industry in the western region. The key is to adhere to the innovation driven transformation upgrading. The reporters from

found that coal chemical industry was hard to find in the "newly encouraged industries in the western region" in the officially released "Catalogue", except for a few extension industrial chain projects such as deep processing of coal tar. In the draft, a number of provinces have listed "annual output of more than 500000 tons of coal through methanol to olefins, annual output of more than 1 million tons of coal to olefins". The industry believes that this adjustment has taken into account the recent calls from all walks of life for the rational development of coal chemical industry.

"in recent years, the problems of repeated construction blind investment in coal chemical projects in the western region are really serious, resulting in the convergence of coal chemical product structure, serious overcapacity, large amount of investment waste, which can not be said to be a decision-making error." Guo Weidong, a chemical expert director of the office of Shaanxi Provincial decision-making advisory committee, told reporters that, for example, Shaanxi's orchid charcoal production capacity is as high as 7000 tons, the current annual output is less than 20 million tons, which is a serious waste of production capacity. If the transformation upgrading are not driven by innovation, there is no way out for the development of coal chemical industry in Western China.

Guo Weidong believes that coal will still be the main energy source in the next 50 years in view of China's basic national conditions of rich coal, less oil gas the strategic dem to ensure energy security. Although the industrial catalogue has been adjusted, the development space Prospect of coal chemical industry in the western region are still very large, which should be developed orderly vigorously. The government should not only guide the development of the industry, but also guide the development of the industry.

"the problem now is that western enterprises do not have enough awareness of innovation attach importance to new technologies, lack foresight, which is far inferior to that in the eastern region." Guo Weidong called on western enterprises to pay attention to the major cutting-edge technology trends of coal chemical industry make reserves for transformation upgrading. For example, in the future coal based polygeneration, methanol to olefin can be connected with dry distillation of pulverized coal continuous gasification of pulverized coke; the cost of coal plasma acetylene production technology is about 30% lower than that of calcium carbide route; the time process of micro reaction technology is very short, large-scale chemical equipment is miniaturized, the production cost of many chemicals will be greatly reduced.

reporters learned that since this year, the chemical industry investment in the western region has shown a downward trend. Among them, a number of large-scale modern coal chemical projects under construction in Shaanxi are under started the investment is not in place. However, Shaanxi's key projects of modern coal chemical industry have a strong momentum. By the end of this year, three coal to olefin projects have been completed put into operation, with a total capacity of 2.5 million tons; the coal to oil projects with four process routes will have a capacity of more than 3 million tons in the first half of next year; the process package of 1 million tons of coal to aromatics project has been developed. The end products of

,

"coal to olefin" projects in Western China are mostly polyethylene polypropylene, with a single product structure, which is actually very risky Guo Weidong appealed that the development of modern coal chemical industry should not follow the trend. When supporting ethylene propylene products, more consideration should be given to the future market potential, high value-added frontier products such as fine chemicals should be developed.

,

Guo Weidong suggested that coal to methanol enterprises should find a way out for further processing. The following derivatives, such as polymethoxydimethyl ether (dmm3-8) Dimethoxymethane, have a market space of at least 20-30 million tons; toluene xylene are dependent on imports. In addition, China's methanol to aromatics technology has broken through, methanol production capacity can also be digested.

news quick discussion on the rational choice of

rational choice of

of the catalogue of encouraged industries in the western region to withdraw modern coal chemical projects, which releases three signals to the industry. Firstly, the development of modern coal chemical industry in China is not smooth. From the effect of coal to olefin other modern coal chemical demonstration, although the process technology is feasible in general, some demonstration projects encounter bottlenecks such as unstable technology, substard environmental protection water shortage. Especially in the western region, coal water resources are in reverse distribution, the contradiction between the high water consumption of coal chemical industry the lack of water resources in the western region can not be reconciled. This revision of the catalogue is a wise move to fully listen to the suggestions of all parties. Second, under the new normal, China's economic development ideas have changed. General secretary Xi Jinping recently pointed out clearly that "we need to have beautiful scenery Jinshan Yinshan. It's better to have green water green mountains than gold silver mountains, green waters green mountains are golden mountains silver mountains. " The adjustment of the catalogue once again shows that China's development thinking is no longer only based on GDP, but also pays more attention to the relationship between development environment. It is better to slow down the development protect the environment. The ecological environment in the western region is fragile the environmental capacity is very limited. It is beneficial to protect the environment of the western region by restraining the rapid development of coal chemical industry in the western region. Third, in the long run, cooling is conducive to the healthy development of modern coal chemical industry. The adjustment of the catalogue clearly shows that the government's attitude towards the development of coal chemical industry has changed from encouragement to prudence. In the short term, the development of coal chemical industry has been restrained, but it just gives time space for modern coal chemical industry such as coal to olefin, coal to oil gas, etc., to optimize technology, improve process, sum up experience, pour a ladle of cold water on those enterprises with hot minds blind development of coal chemical industry to make them wake up more clearly. It also provides time for all sectors of society to reach consensus on the development of modern coal chemical industry, which is undoubtedly a good thing for the healthy development of modern coal chemical industry in China.
