According to the Asian-based business consulting firm (ASIACHEM Consulting) to a new report by the textile industry and the cotton boom of increasing the impact of soaring prices, China fiber market in 2010 strong growth in consumer demand, production and sales both showing a substantial increase in prosperity scene. Polyester products have high profits have driven manufacturers to expand production. 2010 China added 4.09 million tons / year of polyethylene terephthalate (PET) production capacity in 2011 will add 4.7 million t / production capacity,
CAS 512-26-5, then the total capacity will reach 33.5 China PET tons / year.
PET's main raw material for terephthalic acid (PTA) and ethylene glycol (MEG), PET requires 0.86 tons per ton of PTA and 0.34 tons of MEG. In China, over 90% of PTA and MEG for the production of PET. PET is mainly used for production of polyester fibers, films and plastic products.
Polyester industrial development has been driven by strong consumption growth MEG. According to the Asian-based business consulting firm data show that in 2010 production reached 22.67 million tons China PET,
fine chemicals wholesalers, MEG consumption reached 7.71 million tons. If in 2011 China's polyester industry capacity utilization was 75%, then the production will reach 25.12 million tons PET, MEG consumption will reach 8.54 million tons.
There are two main processes currently CTMEG routes, one is synthesis gas (carbon monoxide and hydrogen) system for MEG, the other is based on the methanol to olefins (MTO) technology, these two are based on coal as the basic raw material. Data, using the first line of a process, one ton of MEG takes about 5.66 tons of coal, production cost is lower than 4000 yuan / ton. At current market prices, if the stability of large-scale production, will bring very substantial profit. China's first use of syngas MEG demonstration plant - the coal chemical industry in Inner Mongolia Gold Tongliao Tongliao 150,000 tons / year plant is still in the experimental stage, when the realization of commercial production has not yet determined.
The MTO technology CTMEG based production process has confirmed commercial demonstration plant. Shenhua and Dow Chemical plans to jointly develop Yulin coal-olefin (CTO) and CTMEG projects. China's southeast coastal areas have a good receiving liquid chemicals terminal and logistics infrastructure, and these regions or China's MEG major consumer market. Taking into account the global market including China's methanol production capacity surplus, these areas can be developed based on the MTO project purchased methanol, the final production MEG. Ningbo Heyuan Chemical has begun to create a methanol to olefins project, expected to be completed within two years,
Lead Citrate, the project designed to handle 1.8 million tons per year of methanol, to produce 60 million tons of olefins. The project is the final product will be 50 million tons / year MEG and 30 tons / year of polypropylene (PP). Source: www.mhcfm.com
