中国是世界上最大的聚酯(PET)生产国,到2012年底PET产能3 880万t。由于其原料对二甲苯(PX)来自于传统石化路线,国内供应不足,需要大量进口,2012年净进口量约609万t。2013年净进口量预计将达到870万t。受环保因素制约和公共舆论影响(特别是在沿海地区),国内石化路线的PX产能增加将十分有限。由于国内PTA的产能将快速增长,预计到2015年底达到5 000万t/a,亚化咨询研究显示,假如2015年
China is the largest producer of polyester in the world with a capacity of 38.8 million tons of PET by the end of 2012. Due to its raw material paraxylene (PX) coming from the traditional petrochemical route, the domestic supply is insufficient and needs to be imported in large quantities. In 2012, the net import volume was about 6.09 million tons. Net imports in 2013 are expected to reach 8.7 million tonnes. Constrained by environmental factors and public opinion, especially in the coastal areas, PX production capacity of domestic petrochemical routes will have limited growth. Due to the rapid growth of domestic PTA production capacity, it is estimated that by the end of 2015 it will reach 50 million t / a. As a result of the research conducted by ASIA, if 2015
