I would like to ask for empirical values of tray efficiency when simulating distillation columns
Thread Content
I would like to ask everyone about the values of tray efficiency used when simulating distillation columns – specifically for different types of columns (feed columns, atmospheric columns, vacuum columns, gas separation columns) – as well as the values of tray efficiency at different locations (feed tray, mid-stage reflux, etc.).
It’s hard to generalize; it depends on practical experience. This is just my personal opinion for reference only
Can the tray efficiency of a distillation column be calculated? I can’t figure it out
There are usually two types of efficiency: one is the overall tower efficiency, which is primarily used in design and can generally be calculated using O’Connel’s empirical formula; for more conventional systems, an efficiency of 50% is usually sufficient； A type related to the Moffat plate efficiency, which is used more in theoretical analysis.
