Diagnostics™ Scans of Centre Downcomers Assist in Determining Tray Capacity Limits A FCC Debutaniser had been equipped with 2-pass valve trays. With plant expansion being considered, engineers had performed simulations of the Debutaniser and were concerned that at higher rates the Debutaniser would exceed the tray capacity limits. In addition, at the current operating rate, the Debutaniser overhead stream was slightly off-specification. Before deciding on how to revamp the Debutaniser, plant engineers wished to have a better look at the existing tray hydraulics. |
