Second, the methanol industry should establish a cooperation platform for the purpose of "win-win"

China's independently developed coal to ethylene glycol technology has embarked on the journey of industrialization in the past two years, but at the same time, the investment fever of coal to ethylene glycol projects has also aroused the concern of industry experts. At the first coal based ethylene glycol technology and economy seminar held in Shanghai at the end of May, experts proposed that in order to avoid blindly following the trend in the construction of coal based ethylene glycol projects, we should reasonably choose the investment location according to the actual situation, and establish a technical cooperation platform with the principle of "win-win" battery extrusion tester: put the battery between two extrusion plates as the goal, so as to improve the international competitiveness of the coal based ethylene glycol industry, Avoid the situation of overcapacity of domestic methanol and acetic acid that has occurred before

in view of China's national conditions, the growth of domestic ethylene glycol production capacity will be mainly driven by the coal route, and the industry is striving to make the innovative technology of coal to ethylene glycol lead the world. At the beginning of last year, the state has listed coal to ethylene glycol technology as one of the five major demonstrations of modern coal chemical industry, and included it in the national petrochemical industry adjustment and revitalization plan. At this meeting, the impact resistance testing machine system can play a greater role in scientific research experiments. Some experts pointed out that in the process of implementing this strategy, in order to achieve the healthy development of the industrialization of coal based ethylene glycol, some "matters" need to cause in-depth thinking

establish a technical cooperation platform with the goal of win-win.

experts put forward that in the current market pattern of tripartite competition among coal based ethylene glycol, domestic oil route ethylene glycol and imported ethylene glycol, win-win cooperation is particularly important. Especially in the process of promoting coal to ethylene glycol, enterprises should establish a cooperation mechanism of "knowledge innovation, technological innovation and engineering industrialization" through industry associations and technology property rights trading platforms in accordance with the requirements of national industrial policies, so that advanced and applicable technologies can be effectively promoted

some experts pointed out that many enterprises are still developing coal to ethylene glycol technology in the name of "innovation", spending a lot of investment and manpower, and they do not know when they will succeed. Rather than spend these investments on their own development, it is better to introduce technology and carry out cooperation more efficiently, and the project is launched faster. Yaoyuangen, deputy director of the Fujian Institute of material structure of the Chinese Academy of Sciences, said that after 30 years of efforts, their institute has successfully developed the internationally leading 10000 ton coal to ethylene glycol complete industrial process technology with independent intellectual property rights. In this process, they have always insisted on cooperating with enterprises

the agglomeration industrial chain grows together with polyester

at present, 60% of domestic polyester users are concentrated in East China; Most coal to ethylene glycol projects are built in coal producing areas in the central and western regions. The ethylene glycol produced will be transported as liquid dangerous chemicals, which will increase the cost. Take Erdos, Inner Mongolia as an example, which is nearly 2000 kilometers away from Shanghai. How much do you know about the software functions and performance characteristics of the iron tensile stripping experimental machine? The cost of road transportation is 334 yuan per ton, plus storage, loading and unloading, insurance and other expenses

Xia Lei, general manager of Asiatic chemical consulting, believes that "integrated coal to ethylene glycol and polyester" in coal producing areas is the development direction. That is to build the ethylene glycol project in the coal chemical industry base in the coal producing area, and use the gas production and air separation units of coal chemical industry, as well as the produced chemical raw materials to produce ethylene glycol; At the same time, p-xylene (PX) is produced by methanol to aromatics technology, and then terephthalic acid (PTA), another raw material required for polyester, is synthesized. Then PTA and ethylene glycol are used to synthesize solid polyester

Xia Lei believes that this route is easier to transport than liquid ethylene glycol and methanol, and the added value of the product is also higher. It is reported that Tsinghua University and Shanxi Institute of coal chemistry, Chinese Academy of sciences are currently developing methanol to aromatics technology. After a breakthrough is achieved, PTA can be obtained from the coal based methanol route

steady development to prevent the project from "following the trend"

coal to ethylene glycol project is a project with high investment, high consumption of resources and occupying more land. Experts remind that we should be far sighted in investment and construction. We should see that in the next three years, China's Polyester output is likely to achieve rapid growth and maintain a high demand for ethylene glycol; At the same time, it should also be noted that the polyester growth rate will decline after 2012; In addition, more than 60% of the total global consumption of ethylene glycol is in China

As one of the most developed countries in carbon material industry, Japan needs to pay attention to another problem that the ethylene glycol production base in the Middle East has accelerated in recent years. By 2013, the ethylene glycol production capacity in the Middle East will reach 8.62 million tons, mainly exported to Asia, especially China. With the growth of China's coal based ethylene glycol production capacity, China's ethylene glycol industry will face fierce competition from imported ethylene glycol. Wei Jianhua, vice president of Shanghai Huayi (Group) Co., Ltd., proposed that enterprises must consider the market reality when launching glycol projects, carefully conduct technical and economic analysis, and make scientific decisions. Wei Jianhua specially reminded that with its cost advantage, imported ethylene glycol may adopt the strategy of price reduction competition, and domestic coal based ethylene glycol enterprises must prepare in advance
