对二甲苯(PX)是国际上芳烃产业利润最大的产品。国内PX产业在建厂及运作中出现了一系列问题,导致国内PX产量供给严重不足,每年都需要大量进口PX。对国内PX产业现状及产业发展中的问题进行了分析,对我国PX产业的发展提出对策建议:希望通过政府严格制定安全及环境管理标准,正确引导公众舆论、优化产业布局,推动PX纵向一体化发展、依托一体化大炼油,发展PX产业集群、优化PX下游产业,以产品附加值提高经济效益、以国际市场为视角,提高PX的装置管理及生产安全水平等建议的提出,可以为我国PX产业的发展提供参考。
Paraxylene (PX) is the most profitable product in the aromatics industry in the world. A series of problems have arisen in the construction and operation of the domestic PX industry, which has led to a serious shortage of domestic PX production and a large number of PX imports each year. Analyzed the current situation of domestic PX industry and the problems in industrial development, and proposed countermeasures and suggestions for the development of China’s PX industry: We hope that the government will formulate safety and environmental management standards, properly guide public opinion, optimize industrial layout, and promote PX vertical integration. To develop, rely on integrated large oil refining, develop PX industrial clusters, optimize PX downstream industries, increase value-added products to improve economic efficiency, view the international market, and improve the PX’s device management and production safety, etc. The development of the industry provides a reference.
