近年来,我国对二甲苯工业装置规模日趋大型化,装备本土化比例有所提高,技术水平明显提升,综合竞争能力显著增强,已成为世界最大的PX生产和消费国。截至2012年9月底,我国PX生产企业13家,生产能力826.1万吨/年,约占全球总产能的20%;2011年表观消费量1132.7万吨,约占全球消费量的30%,对全球PX生产及其下游产业链的发展具有举足轻重的影响。预计到2015年,国内PX的总生产能力将达到约1430万吨,需求量2070万吨。产量不能满足国内实际生产的需求,仍需大量进口。
In recent years, the scale of China’s paraxylene industrial plant has become larger and larger, the proportion of equipment localization has been raised, the technical level has been significantly improved, and the comprehensive competitiveness has been significantly enhanced. It has become the largest PX producer and consumer in the world. As of the end of September 2012, there were 13 PX production enterprises in China with a production capacity of 8,261,000 tons / year, accounting for about 20% of the global total production capacity. In 2011, the apparent consumption was 11,327,000 tons, accounting for about 30% of global consumption. The global PX production and the development of its downstream industrial chain have a decisive influence. It is estimated that by 2015, the total domestic PX production capacity will reach about 14.3 million tons and the demand will be 20.7 million tons. Production can not meet the actual needs of the domestic production, still need a lot of imports.
