Discussion on ethylene glycol technology
Thread Content
Discussion on ethylene glycol technology: The current ethylene glycol production technology in China is that of Danhua Technology; it is mainly used in Tongliao, Inner Mongolia, with a production capacity of 200,000 tons. In 2009, this facility became the first in China to produce ethylene glycol from coal, but as of now, its utilization rate is only 70%； Currently, the Danhua technology has been extended to 1 million tons in Henan (Anyang, Xinxiang, Yongcheng, Luoyang, Puyang), and pilot operations have been carried out; the issue encountered is still one related to polyester quality. The Ube Technology plant in Japan is currently under construction; as for the specifics, it remains to be seen by the market ； The technology developed by Shanghai Pujing has been applied at Anhui Huaibei Chemical. Reportedly, the 1,000-ton pilot project has been successful, and a 100,000-ton facility is currently under construction ； The New Era Pu Jing technology in Inner Mongolia is also under construction, and the 10,000-ton class technology still needs to be tested by the market ； The 50,000-ton capacity facility of Hualu Hengsheng has been put into operation, but it still does not meet the requirements for polyester grade or similar standards ； In other words, coal-based ethylene glycol production still needs further exploration and market testing; currently, no company in China is able to operate at 100% capacity. Technical secrecy hinders the progress of this technology. I hope everyone will actively discuss the technology of coal-to-ethylene glycol.
Our institute is also working on a project to produce ethylene glycol from coal; I’m not sure whose technology is being used, but it is said to be foreign technology. . . .

80% is already stable, no problem
Hello, I heard that Yanchang is also very interested in Pujing Technology; they have signed a technical contract, but it seems they haven’t signed a commercial contract yet.
The contract has been signed. It uses Pu Jing’s technology
The secrecy measures in place regarding ethylene glycol technology in China are a bit excessive; I was denied entry at Tianye, and I was also refused admission at Tongliao Jinmei. It feels like we haven’t reached a level of full absorption and communication. Puyang has already reached the polyester level. Xinjiang Tianye 99% polyester grade.
With such fierce competition nowadays and extensive expansion activities, maintaining secrecy is inevitable
Hello, friend. I see that you are also in the ethylene glycol industry; I work in this same field as well. Would it be possible for us to exchange ideas? If it’s convenient for you, could you share your QQ number?
