Process optimization and industrial application ofSRH liquid phase hydrogenation technology for jet fuel production

SRH液相加氢工艺是中国石化开发的新型加氢技术。该工艺反应部分不设置氢气循环系统,依靠液相产品循环时携带进反应系统的溶解氢提供加氢反应所需要的氢气。结合3号喷气燃料(航煤)加氢装置氢耗低、反应相对缓和的特点,中石化洛阳工程有限公司以SRH液相加氢技术为平台,将航煤生产和常减压装置进行了深度整合,开发了一项新型的航煤加氢工程技术。文中着重介绍了该SRH液相加氢技术生产航煤的工艺优化及工业应用。应用结果表明:该工艺技术能够生产符合标准要求的航煤,同时具备流程简洁、设备少、占地面积小、能量利用率高等特点,具有良好的应用前景。

SRH liquid phase hydrogenation process is a new hydrogenation technology developed by SINOPEC.The reaction part of the process is not equipped with a hydrogen circulation system,which relies on the dissolved hydrogen carried into the reaction system during the circulation of liquid phase products to provide the hydrogen needed for hydrogenation of fresh feedstocks.Combined with the characteristics of low hydrogen consumption and relatively mild reaction of jet fuel hydrogenation unit,SINOPEC Luoyang Engineering Co.,Ltd.has developed a new jet fuel hydrogenation technology based on SRH liquid phase hydrogenation technology,which deeply integrates No.3 jet fuel production unit and atmospheric and vacuum distillation unit.The process optimization and industrial application of SRH liquid phase hydrogenation technology in the production of No.3 jet fuel are introduced.The application results show that the technology can produce No.3 jet fuel which meets the standard requirements.At the same time,it has the characteristics of simple process,fewer equipments,small floorage,high energy utilization rate,and has a good application prospect.
