The real reason of success or failure of coal chemical industry

wallpapers News 2020-10-30
Recently,

news about the restructuring of coal chemical industry frequently appeared in various media. The collective withdrawal of central enterprises such as Datang CNOOC has triggered a debate on the prospect of coal chemical industry. But many analyses are not in place.

can be summed up in two sentences: "if the coal quality is correct, the management stard will be smooth". The failure of coal chemical projects is mainly caused by the wrong coal quality. Considering the security of clean energy supply in China, it is necessary urgent for China to develop coal chemical industry. After more than ten years of demonstration project construction, the emerging coal chemical industry composed of coal to oil, coal to natural gas, coal to olefin coal to methanol has begun to take shape. The demonstration project shows that there is no subversive problem in the technology of the above coal chemical projects, the successful experience failure lessons have really played a demonstration effect, which can be used as a guide for the development of coal chemical industry in the next step. If the coal quality is right, even if the investment is large the coal price is high, the project will not die prematurely through effective management; on the contrary, if the coal quality is not right, even if the investment is small the coal price is low, the management is stard, the project will inevitably die. In other words, if the preliminary work of the project is not sufficient, although the coal quality is right, due to the reasons such as excessive investment, long construction period mismatched external conditions, the economic benefits of the project will be poor, but it can be reversed through efforts. In other words, the success or failure of coal chemical projects economic benefits directly depend on the coal quality. Coal quality of

requires coal to be suitable for gasification process. Generally speaking, "coal gasification" is to effectively economically "transform" coal, which is also the characteristics difficulties of coal chemical engineering. The lessons of

coal quality are everywhere. If Datang coal chemical project located in Keshiketeng Banner, Inner Mongolia, was located in Ordos (600295, Guba) area or Yulin area, using bituminous coal instead of lignite, it would certainly be another scene. It is hard to imagine how much courage it would have taken to invest heavily in the construction of coal chemical projects in xilingle League, where the coal industry was underdeveloped, the coal output was low, the research utilization of coal were almost zero.

coal are rarely used, so the problems in use are not easy to find out, the characteristics of coal quality are unknown. It is not surprising that such other problems appear in coal gasification (000968, Guba). Some problems are not fundamental can be solved through process adjustment. However, some problems are fundamental can hardly be solved effectively. If the coal quality is right, the price of raw materials must be competitive to a certain extent. For projects with the same process scale, the price of raw coal is 200 yuan / ton 500 yuan / ton. The economic benefits are clear at a glance. For example, for the construction of coal chemical projects with lignite as raw materials, the technical economic comparison between lignite gasification flue gas gasification should be carefully studied. In decision-making, it must be clear whether the lignite coal gasification project is competitive with the gas coal gasification project. It is generally believed that lignite is cheaper than bituminous coal, but the key problem of whether the mining cost is cheap or not is ignored, as well as the low calorific value, low gasification efficiency complex pre-treatment of lignite. The mining cost is not low, implying that the competitiveness of coal price is not strong. The management stard of

is in accordance with the

. Some projects with wrong coal quality are under green light for construction. However, when they are completed, they will lose money, or when they are completed, they will be transformed. This involves management. In the face of a failed project, we can not help but ask: is the feasibility study report stard? Investment decision stard? Approval stard? Engineering design specification? Important key equipment procurement specification? Bank loan approval specification? As long as one of the links is stardized plays its due role, we will not face such a dilemma. Although the management of

is not the main reason for the success or failure of the coal chemical project, the important reason for the failure of the project is that the preliminary work of the project is extensive the management is not stardized. If the Adaptability Study of coal quality is carefully carried out in the preliminary work, the most suitable gasification process is selected, or the raw coal is not suitable for gasification through research, the possibility of project failure is eliminated from the root. There are many reasons for the nonstard management of

. The owner is not responsible for all of them. The preparation unit of feasibility study report, engineering design unit key technology provider are all responsible. In the feasibility study of some projects, the selected coal price is much different from the actual production coal price; some projects have the appropriate coal raw materials in the feasibility study stage, but after the completion of the project, the appropriate coal raw materials will not be produced, so the raw coal must be purchased from afar, resulting in serious losses; some projects investment exceeds the budget the construction period is prolonged; This is all related to the work of the design department, which is also a management problem. When introducing their own technology equipment, the technology supply department often publicizes its own technology equipment, which also leaves hidden dangers for the failure of the project. The coal quality of

is the right way. In the early stage of the project, we must seriously study the coal quality problems try our best to be comprehensive precise. When Shenhua Group investigated the coal quality of Ordos coal to oil project, it made a detailed investigation on the change law of coal quality the coal quality situation in this area in the next 3-5 years. The coal quality research of

also involves the important matters in the preliminary decision-making such as the project construction site. For example, coal water slurry gasification needs coal raw materials with relatively low ash content low ash melting point. Most coal mines with high ash content high ash melting point are located in Liupanshui area of Guizhou Province. If coal water slurry gasification project is built in this area, there will be only two results after completion: either stop production transformation, or poor benefit. Any construction project of

has investment risk. The biggest risk of investment project related to coal is the risk of "coal quality". Coal mine investment also has many failure lessons, summed up the basic problem is the coal quality problem. Some of them blindly invest in the construction of coal mines without knowing whether they are lignite or bituminous coal, while others rashly invest in the construction of so-called coking coal mines without confirming whether they are coking coal. Therefore, there are some problems in the emerging coal chemical projectsInevitably, it is urgent to strengthen the stardized operation. "
