Learn why HETP may increase in a random packed distillation column and how to troubleshoot liquid maldistribution, hydraulic loading, fouling, poor wetting, packing damage and changing process conditions.

Learn how to diagnose liquid maldistribution in a random packed tower, including distributor blockage, wall flow, dry zones, poor turndown, localized flooding and practical corrective actions.

Learn how to diagnose flooding in a random packed tower, including pressure-drop symptoms, gas and liquid overload, fouling, foaming, distributor problems and practical corrective actions.

Learn when replacing trays with random packing makes sense in an existing column, including pressure drop reduction, capacity debottlenecking, packed height, liquid distributors, internals and retrofit design checks.

Learn when random packing is suitable for TEG gas dehydration contactors and how to compare random packing, structured packing and trays based on pressure drop, glycol distribution, hydraulic capacity and operating conditions.
