China's production material ethylene-propylene rubber status

China's ethylene-propylene rubber consumption in 2002 to 29,000 tons / year and is expected to ethylene-propylene rubber in 2006, the total consumption will reach 60,000 tons / year, the need for new production capacity to meet rapidly growing demand. Domestic Kyrgyzstan, Yanshan Petrochemical Corporation are considering a new ethylene propylene diene monomer (EPDM) device, DSM would like to have long Chinese New ethylene-propylene rubber plant, according to media reports, Bayer is considering investments in Caojing, Shanghai, more than 200,000,000 U.S. dollars SBR to build devices and ethylene propylene diene monomer (EPDM) device, Japan's Mitsui Chemicals, China is considering building a high-performance production of ethylene-propylene elastomer (Eptalloy, ethylene-propylene alloy) plant. If the ethylene-propylene rubber completion of the new device, the location of the new device ethylene, propylene, the third single of the development will affect the ethylene-propylene rubber-effectiveness of new devices.

1. Ethylene

At present, the existing ethylene production of 18 sets of equipment, production capacity of 10,000 tons in 3O / year or more sets of production equipment, only 7 (Yanshan Petrochemical, Shanghai Petrochemical 2 ethylene, Sinopec Qilu, Yangzi Petrochemical, Maoming Petrochemical and Daqing Petrochemical, Jilin Large petrochemical ethylene) and the rest of the plant (Tianjin Petrochemical, Sinopec Zhongyuan, Guangzhou Petrochemical, Jilin Petrochemical Ethylene small, Lanzhou Petrochemical, Fushun Petrochemical, Dushanzi Petrochemical, Liaoyang Chemical Fiber, Oriental Chemical, Panjin Ethylene, Shanghai Petrochemical Ethylene 1) production Most of the capacity of 200,000 tons / year. Economies of scale in today's ethylene industry trends. 2001 world-scale ethylene plant has reached an average of 427,000 tons / year, the largest size of the device has reached 1,890,000 tons / year. The average size of the ethylene plant in China to 247,000 tons / year, far below the world average size. At present, China's ethylene industry and foreign ethylene, the main gap is also reflected in the level of technology and equipment, seized maintenance cycle, energy materials, as well as staffing, and other areas, resulting in China's ethylene industry cash operating costs, low economic efficiency Situation.

In recent years, China's output of ethylene to maintain the momentum of steady growth. China's ethylene production in 2000 to 4,690,000 tons in 2001 China's ethylene production reached 4,790,000 tons, curly 1.O2 growth over the previous year. Ethylene production in 2002 was 5,400,000 tons, more than 113 curly growth in 2001. 2003 is expected to produce 5,900,000 tons.

China's demand for ethylene in the future will have a larger gap is expected that by 2005, the consumption of ethylene in China will reach 15,000,000 tons / year ethylene production capacity will double over the same period, reaching 8,300,000 tons / year, nearly half still Ethylene equivalent to rely on imports to meet demand. Ethylene consumption in 2010 will reach 19,000,000 tons / year ethylene equivalent is still a shortage of petrochemical products. To this end, the world's major multinational companies optimistic about China's ethylene market will continue to expand business opportunities, one after another to participate in China's ethylene industry's large-scale operation. 5 multinational companies - BASF, BP, Shell, ExxonMobil and Dow Chemical Company in China, set up 6 large-scale ethylene joint venture, ExxonMobil set up 2.

Lummus Corporation (ABB Lummus Globa1), KBR Inc. and Stone Wibert e-companies are interested in the cracker is expected to 750,000,000 U.S. dollars of investment, is expected to be the first built in 2008.

2. Propylene

China's current production of propylene nearly 50 enterprises, of which the production of propylene steam cracker 16, for the rest of the refinery propylene manufacturer.

In recent years, China's output of propylene to continue to grow larger increase. Propylene production in China in 2000 to 4,693,100 tons in 2001, China's output of propylene to reach 4,778,500 tons, 1.8 percent increase over the previous year. Propylene production in 2002 to 5,320,700 tons, representing 12.1 percent growth in 2001. 2003 is expected to produce 5,700,000 tons in 2005 to 6,730,000 tons.

Propylene China's fast growth in consumption, in 2000 China's apparent consumption of propylene to 4,856,000 tons in 2001 Chronology of view of consumption of 5,047,700 tons, compared to 2000 growth of 4.0 percent. Chronology of 2002 outlook for the consumption of 5,617,600 tons, representing 11.3 percent growth in 2001. 2003 is expected to China's market for propylene, the total demand of about 6,000,000 tons, propylene supply and demand gap of about 300,000 tons. Propylene demand in 2005 will reach 9,530,000 tons, propylene supply and demand gap of about 2,800,000 tons, self-sufficiency rate of 70.6 percent.

In the past two years China's import volume of propylene a sharp increase in imports in 2002 amounted to 296,900 tons of propylene than the 9.7 percent growth in 2001, imports accounted for about domestic consumption of 5.3 percent.

3. The third monomer

So far, the industrial production of ethylene propylene diene monomer (EPDM) in the third monomer used in a fork B Norbornene (ENB), Dicyclopentadiene (DCPD) and 1,4 - 3 hexadiene . B fork Norbornene (ENB) mainly depend on import. Nippon by the company, Sanyo and Dow Chemical Co., Ltd. joint venture chemical composition of the Sunrise recently in the United States Pasadena, Texas, put into operation a 20,000 tons / year fork B Norbornene production, Sunrise Chemical Company is the world's largest B Norbornene and manufacturers. Dicyclopentadiene is cyclopentadiene dimer of the world with an annual output capacity of 450,000 tons, the major producers are Dow Chemical, Exxon Mobil, a Seoul Leon, Shell and the company Texmark. In addition, the Japan Synthetic Rubber, Jason, Hitachi Chemical and Maruzen Petrochemical production companies Dicyclopentadiene. According to reports, this study N i PP 0 n petrochemical companies in Kawasaki, Japan (Kawasaki) a set of new production capacity of 10,000 tons / year of Dicyclopentadiene (DCPD) production equipment will be installed in August 2003 Started.

Dicyclopentadiene large-scale installations are cracking c5 as raw materials, mainly oil producers have Liaoyang Chemical Fiber Corporation and the Shanghai Dickinson resin oil companies. The Liaoyang Chemical Fiber Company oil production for the purity of 85% main Dicyclopentadiene of European exports, low load to start.

Dicyclopentadiene domestic consumption structure are very different. Abroad, mainly for the production of high-saturated hydrocarbons in a transparent resin. Major used in the production of unsaturated polyester, ethylene-propylene rubber and petroleum resin, and so on. 2005 Dicyclopentadiene domestic production of 1.5 million tons of a total requirement of 30,000 tons, the shortfall of about 15,000 tons. 2010 annual production of about 20,000 tons, the total demand of about 40,000 tons, 20,000 tons gap.

1,4 - has been diene monomer for only the third U.S. company DuPont.

With the production of ethylene propylene diene monomer technology development, people also developed new production of ethylene propylene diene monomer in the third monomer, there are several.
