近年,全球石油开采量逐年递增,原油重质化、劣质化的趋势不断加剧,而劣质石油产品的使用造成了严重的环境污染。随着社会对环境保护的逐渐重视,为获得高质量高附加值的油品,减轻石油石化产品在使用中对环境的污染,各炼油企业加大了原油深度加工和二次加工装置的规模。在炼油企业中,采用高温高压加氢精制技术已有50多年的历史,随着加氢劣化、加氢脱硫等工艺改进,带动了加氢反应器制造技术的改进和材料的更新换代。自2012年以来,我国中东部地区陷入
In recent years, the global oil exploration volume has been increasing year by year. The trend of heavy and inferior crude oil has been aggravated. The use of inferior petroleum products has caused serious environmental pollution. As society pays more and more attention to environmental protection, in order to obtain high-quality and high-value-added oil and reduce the environmental pollution caused by the use of petroleum and petrochemical products, the refineries have stepped up the scale of deep-processing and secondary processing of crude oil. In refining enterprises, the use of high temperature and pressure hydrotreating technology has been more than 50 years of history, with the hydrogenation deterioration, hydrodesulfurization and other process improvements, led to the hydrogenation reactor manufacturing technology improvements and materials replacement. Since 2012, China’s eastern region caught in
