How to diagnose column flooding on a Koch-Glitsch FLEXIPAC / IMTP distillation column
Column flooding causes purity loss and pressure drop spike. Reduce vapor or liquid rate to below the flood point, then diagnose the root cause.
How to diagnose packing fouling on a Koch-Glitsch FLEXIPAC / IMTP distillation column
A slow rise in differential pressure over months indicates packing fouling. Track the trend, plan an inspection at the next turnaround, and consider a column wash before opening.
How to diagnose valve tray weeping on a Koch-Glitsch Provalve distillation column
Tray weeping happens when vapor flow is too low to prevent liquid from draining through the tray. Increase vapor load or inspect for damaged valve caps at the next shutdown.
