摘　　要：全加氢型润滑油装置通常由加氢处理、加氢脱蜡、补充精制3部分组成。由于加氢脱蜡、补充精制多采用贵金属催化剂,为防止贵金属催化剂中毒,对循环氢及反应进料中的硫、氮含量要求高。因此在流程设置上,多数情况下将加氢脱蜡、补充精制作为一段串联布置在加氢处理单元的下游。常规全加氢型润滑油装置需要两套独立的高压反应系统及相关高压设备,即采用两段技术,流程相对较长,且设备较多。通过在全加氢型润滑油生产装置中引入高压氢气汽提技术,将传统的一段加氢处理和二段加氢脱蜡-补充精制两个反应系统整合为一段串联系统,既能缩短原有的加工流程、减少装置占地,又能节省装置投资8%左右,同时使全装置能耗减少12%左右。Full hydrogenation lube base oil production unit usually include hydrotreating,hydrodewaxing and hydrofinishing.As noble metal catalysts are mostly used in hydrodewaxing and hrdrofinishing section,to avoid catalyst poisoning,sulfur and nitrogen content in recycle gas and feed is strictly restricted.As a result,hydrodewaxing and hydrofinishing sections are usually arranged in series downstream the hydrotreating sections.Normal full hydrogenation lube base oil production unit require two separated high pressure reaction systems and relative high pressure equipment.Two-stage technology requires longer process and more equipment.The traditional full hydrogenation lube base oil production unit consists of two reaction stages,1st stage hydrotreating and 2nd stage hydrodewaxing-hydrofinishing.Using the high pressure hydrogen stripping technology,the two reaction stage was integrated into one-stage series system,which could optimize the original process and reduce land occupation,with the investment saved by 8%and the total unit energy consumption reduced by 12%.
