Raschig rings are used as packing material for fractional distillation columns. The extra surface area and random arrangement creates mixing and interaction between the vapor and condensed materials. Raschig rings create a moderate amount of theoretical plates, but have low hold up and pressure loss. This results in a packing type that is good for distillation of viscous materials where clogging or flooding may occur.
