China's PET Production, Consumption and Forecast Analysis – polyester, PET, PTA-plastics industry
Polyester ( PET , Polyethylene terephthalate) is terephthalic acid (PTA) and ethylene glycol (EG) produced through condensation. As the different ways of production and processing, the product is divided into polyester chips, polyester film and polyester (PET’s scientific name), polyester filament and staple fiber points, polyester filament yarn accounted for about 62% of staple fiber about 38%, filament for textile enterprises to use, staple fiber and cotton blended general. Section is divided into bottle grade chips, film grade chips and fiber chips, fiber sections were dissolved spinning into fiber, film grade chips bottle grade and generally no longer used for fiber production. More than 75% of China for the production of polyester fiber polyester, commonly known as polyester, polyester fibers accounted for 85% of the total, the textile industry, the main raw material. Therefore, polyester series of market change and development trend of chemical fiber industry, the focus of attention.
History Polyester ( PE T) was invented in 1944, 1949, the first to achieve commercial production in the UK because there are excellent taking and high strength properties, as in the production of synthetic fibers, the largest species. Polyester 70’s before the 20th century has maintained rapid development, its production growth rate: 200% 1960 1965 50%, 60% in 1970, then slowing down and cyclical trend growth rate in 1975 30% 10% 1982 1987 12.6% 1992 6% 1999 4.3% 2001 4.8% 8% expected in 2004. 90’s of last century, the polyester industry has begun to shift the focus of development in Asia, to the mid-90s, due to excessive capacity expansion, except for China has excess supply situation. By 1999, the polyester industry has ushered in a new stage of development, mainly due to bottle and film grade, composite and other non-increase in the amount of polyester fiber, polyester suits with peak demand. According to the World Congress of polyester, from 1999 to 2005, the polyester production capacity can be increased 33 to 40% annual growth rate of 6.6 to 8%. Since 2000, the world’s polyester industry entered a new round of rapid development.
In the polyester products, polyester fiber non-rapid development. In 1996, world production of polyester packaging resins and films were 4.519 million tons and 1.382 million tons, accounting for 20.7% of the world’s total output of polyester and 6.3% in 1998 were 6.995 million tons and 1.631 million tons, accounting for the world gather ester production of 24.6% and 5.7%. 8.236 million tons respectively in 2000 and 1.769 million tons, an average annual growth rate of 17.6% and 6.2% each in the world polyester production of 26.0% and 5.59%. Projected to 2003, non-polyester fiber polyester production output accounts for about 1 / 3.
PE T is no longer confined primarily to the use of fiber, but to further expand the types of containers, packaging materials, films, film, Engineering Plastics Fields, currently, PET is being increasingly replaced by aluminum, glass, ceramics, paper, wood, steel and other synthetic materials, polyester family have continued to expand.
Status and forecast production and consumption in China
Polyester production in China started late 70’s began to take shape in Shanghai, Tianjin, Liaoyang and other production bases, 80 homemade batch, semi-continuous small-build polyester plant more, according to statistics there are more than 110 .
Present China polyester manufacturer concentrated in two major Sinopec and China National Petroleum Corporation. Sinopec polyester production in 2001 reached 2.0297 million tons, accounting for 69.2% of total production. China’s annual output of 466,100 tons of oil in 2001, accounting for 15.9% of total production. Currently more than 40 major manufacturers of polyester, 2001 at 10,000 tons annual output of more than 29 enterprises, 10 million tons of enterprises 9, 30 tons or more enterprises 4. Yizheng Chemical Fiber Corporation is China’s largest polyester production capacity and production company, polyester production in 2001 reached 1.1085 million tons, accounting for 37.8% of total output; followed by Liaoyang Petrochemical Company, 2001, annual output 407,500 tons, accounting for 13.9% ; Shanghai Petrochemical Company ranks third in 2001 annual output of 383,500 tons, accounting for 13.1%. 2002 PET chip production plant in major production Table 10. In 2002 Sinopec Shanghai Petrochemical production reached 420,000 tons the company, Liaoyang Petrochemical Fiber Company of up to 40 tons, Luoyang Petrochemical Company of 22 million tons, up 210,000 tons of Tianjin Petrochemical Company. China is now the largest polyester manufacturer is Sinopec Yizheng Chemical Fiber Corporation, the total capacity of 1.2 million tons annually, has become one of the world’s top ten producers of polyester. In addition to Yizheng Chemical Fiber, the Chinese polyester large enterprises have Liaoyang Petrochemical Fiber Company, Shanghai Petrochemical Co., Ltd., Tianjin oil Chemical industry Company, Xianglu polyester textiles (Xiamen) Co., Ltd.. The production capacity of about 5 large companies nationwide total capacity of 1 / 3. Shanghai Lian Ji
synthetic fiber company (Shanghai Chemical Fiber Group Corporation, Zimmer AG of Germany, and Shanghai International Shanghai Growth, a joint venture) investment 275 million yuan construction of polyester three projects have been built since 1994, 70,000 tons / years, polyester chips, 30,000 tons / year of polyester staple fiber spinning works, production of polyester chips has been increased to 100,000 tons / year, after completion of third phase formation of 250,000 tons / year fiber grade polyester chips, 3 tons / year capacity of polyester staple fiber spinning.
Jinan Qilu Chemical Fiber Group 160,000 t / a polyester project in February 2003 put into operation, its main equipment localization rate of 92%. Supporting the project with 70,000 tons spinning staple fiber project in the first half of 2002 production.
Zimmer Wujiang Chemical Fiber Weaving Factory Chinese company will build a world-class scale polyester plant, polyester polycondensation plant for the Wujiang provide technology, equipment, engineering and start services, installation capacity of 350,000 tons / year of textile grade polyester About 90% of the capacity for direct spinning POY and FDY, the rest of the production of polyester textile chips.
Wujiang Chemical Fiber Factory 300 thousand tons of new equipment will be purchased / year purified terephthalic acid (PTA) and 12 tons / year ethylene glycol. The device contract worth about 30 million U.S. dollars, plan completed in April 2004. After the completion of the new devices will further additional investment in the company. Jiangyin Huaxi Zimmer company also building a textile grade polyester woolen mill plant, plant capacity is 210,000 tons / year. In addition, the Zimmer company for the world’s largest polyester plant of Yizheng Chemical Fibre Company building 1800 tons / day of textile grade polyester plant. Yizheng Chemical Fiber Polyester its ability to be expanded to 500,000 tons / year by 2005 to reach 1.5 million tons / year.
