Random Packing
Mass-transfer media for absorption, stripping, distillation and gas–liquid contacting — in metal, plastic and ceramic.
Choosing a random packing material
Random packing fills the bed of a packed column, creating the gas–liquid contact surface that drives absorption, stripping and distillation. Selecting the right packing means balancing surface area, void fraction, pressure drop and mechanical strength — which vary most between the three material families below.
