A complete understanding of ejector system performance characteristics can reduce the time and expense associated with troubleshooting poor crude vacuum distillation unit (CVDU) performance.
Variables that may negatively impact the ejector-system performance of vacuum-crude distillation units include utilities supply, corrosion and erosion, fouling, and process conditions.
Table 1 [126,182 bytes] and Table 2 [127,553 bytes] are troubleshooting guides to ejector and condenser problems in vacuum-ejector systems. Fig. 1 [158,428 bytes] is a photo of an installed ejector at a CVDU.
