DuPont has 73,000 t/a PTT ME G production facilities in the United States and 45,000 t/a PTT ME G production facilities in the Netherlands, which are supplied to DuPont spandex production plants in the world 1 1 countries. In 2 0 0 4, DuPont Group built a set of 30,000 t/a PTT ME G production equipment in T U A S, Singapore to provide raw materials for spandex production in the local area and other parts of Asia. With the L Y C R A brand as the core, the company plans to increase the production capacity of PTT M E G in the United States to 85,000 t/a and the production capacity of the Dutch factory to 50,000 t/a in 2 0 0 6. In 20001year, bastia company of Germany owned 16000T/a, 23000T/a and 13000T/a P T M E G production facilities in Germany, the United States and Japan respectively. In order to seek development in Asia, the company established a 30,000 t/a P T M E G production plant in Ulsan, South Korea on 1 9 9 8, and the output of the plant reached 33,000 t/a after expansion. BASF's sales direction will gradually shift to Chinese mainland, Taiwan Province Province and Southeast Asia. It is reported that BASF will build a 60,000 t/a P T M E G production plant in China. By then, BASF's production capacity will reach 1.82 million t/a, surpassing DuPont and becoming the largest P T M E G producer in the world. At present, Mitsubishi Chemical Corporation of Japan has 65,438+00,000 t/a production facilities in Shikoku. In order to adapt to the situation that the demand for spandex in the world market has increased greatly in recent years, the production capacity of the newly-built production equipment will reach 30,000 t/a, and the production capacity of the company's P T M E G will be expanded from 65,438+200,000 t /a in 2 0 0 0 to 32,000 t/a in 2 0 0 4. Asahi Kasei Chemical Industry Co., Ltd. of Japan retained the M E G production equipment for Japanese spandex spinning, and its output in 2 0 0 3 reached 4,000 tons. The company and Taiwan Province Formosa Plastics Group jointly established Taiwan Province Formosa Plastics-Asahi Kasei Elastic Fiber Factory, which plans to expand the production capacity of PTMEG in Taiwan Province Province by 65,438+00,000 t/a, but it has no intention to expand the production capacity locally in the next few years, and only seeks to cooperate with Taiwan Province Province to produce PTMeg. In addition, Japanese Baotugu Chemical Company has established a set of 7,000 t/a and 4,000 in Nanyang and Yokohama. PEE EN Chemical Company of the United States has set up a production facility of 25,000 t/a in Tennessee, and P T G Company of South Korea has set up a production facility of 65,438+0.5 million t/a in Ulsan.
By the end of 2009, the global production capacity of PTMEG was about 723,000 t/a. Although BASF closed its THF plant and PTMEG plant in Niigata, Japan in June 2006, it is still the largest PTMEG manufacturer in the world, and the total production capacity of its plants in the United States, Germany, Japan, South Korea and China is 6.5438+790,000 t/a.. ..
Up to 2009, there are 9 domestic PTMEG production enterprises, namely Shanghai Caojing BASF (60,000 t/a, solid acid method), Shanxi Sanwei Group Co., Ltd. (6,543,800 t/a, solid acid method), Dalian Chemical (Jiangsu) Co., Ltd. (40,000 t/a, concentrated sulfuric acid method) and Sinochem Group. Heteropoly acid method), Hangzhou Sanlong New Materials Co., Ltd. (20,000 t/a, heteropoly acid method), Ningbo Mitsubishi Chemical Company (25,000 t/a, solid acid method), China Petroleum Guo Qian Petrochemical Company (20,000 t/a, solid acid method) and Xiaoxing Group (Jiaxing) Co., Ltd. (30,000 t/a, heteropoly acid method), with a total production capacity of 23. However, due to various reasons, these devices failed to produce at full capacity. For example, the PTMEG device of BASF in Caojing, Shanghai, failed to be overhauled in April 2006, and the production load was basically less than half. Since the successful commissioning in June, 2007, Guo Qian Petrochemical Company of PetroChina has not seen the products listed, and the newly-built PT has been built by Hangzhou Sanlong New Materials Co., Ltd., Ningbo Mitsubishi Chemical Company and Xiaoxing Group (Jiaxing) Co., Ltd. Therefore, the actual domestic output of PTMEG in 20 10 is only about120,000 t.
According to rough statistics, the domestic consumption of PTMEG in 20 10 was about 230,000 t, of which 100 t was imported, which was the same as that in 2009. The imported PTMEG comes from Japan, South Korea, the United States and Taiwan Province Province of China. With the commissioning of new equipment in domestic PTMEG industry, the output of PTMEG further increased, and the market showed a situation of oversupply. The spandex industry, PTMEG's main consumption field, has entered a period of steady development, with little increase, and the foreign market has matured. Therefore, the export pressure of PTMEG in China is great, and they have to compete with each other at a price lower than the market. Different from most chemical products, PTMEG manufacturers' products have their own characteristics, and downstream customers have certain dependence, so it is not easy to change raw materials. Under the premise of market saturation, it is difficult for new PTMEG projects to enter the market unless they are digested by themselves.
