Random packing minimum wetting rate

Webbcern. Structured packings are typically used in lower-liquid-rate applications (i.e., less than 50 m3/m2-h), especially where minimizing column pressure drop is important. For similar applications, packings can be expected to have a pressure drop that is a fraction of the pressure drop across trays. Random packings are often used in higher ...
