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.

中心降液管的Diagnostics™扫描可以协助测定塔盘额定容量。FCC脱丁烷塔配有两层浮阀塔盘。考虑到炼厂扩能，工程师对脱丁烷塔进行了模拟，发现在高流体通量的情况下，脱丁烷塔的塔盘将发生过载。此外，在目前的操作条件下，脱丁烷塔的塔顶产品将会轻微偏离其质量规格。在决定如何改造脱丁烷塔之前，炼厂工程师希望对塔盘的水力学特性有一个详细的了解。
