经过30多年的发展,我国石化行业的产品品种、工艺水平等都已经达到世界中、上水平,但与国际先进水平相比仍有差距,主要体现在行业的内在质量水平方面。以炼油、乙烯、芳烃、有机原料、合成材料为典型代表的石油化工领域,其上游是石油、天然气资源的开采,其下游通过深加工可延伸 After more than 30 years of development, the product variety and technological level of China’s petrochemical industry have reached the world’s upper level, but there is still a gap compared with the international advanced level, which is mainly reflected in the inherent quality level of the industry. Petroleum refining, ethylene, aromatic hydrocarbons, organic raw materials, synthetic materials for the typical petrochemical field, the upstream is the exploitation of oil and natural gas resources, the downstream can be extended by deep processing
