Troubleshooting crude vacuum tower overhead ejector systemsUse these guidelines to improve performance and product qualityJ. R. LINES AND L. L. FRENS, GRAHAM MANUFACTURING CO. INC., BATAVIA, NEW YORKR outinely surveying tower overhead vacuum systems canimprove performance and product quality. These vacuum sys-tems normally provide reliable and consistent , process conditions, supplied utilities, corrosion, erosionand fouling all have an impact on ejector system vacuum distillation towers use ejector systems to main-tain tower top pressure and remove overhead gases (Fig. 1).However, as with virtually all refinery equipment, performancemay be affected by a number of variables. These variables may actindependently or concurrently. It is important to understandbasic operating principles of vacuum systems and how perform-ance is affected by: Utilities Corrosion and erosion Fouling Process vacuum -system suppliers have service engineers thatwill come to a refinery to survey the system and troubleshoot per-formance or offer suggestions for improvement.
