Raschig Rings For Fractional Distillation

Fractional distillation relies heavily on the quality of column packing material, with optimal performance being determined by choosing copper mesh and raschig rings as packing options. For the highest level of effectiveness in fractional distillation, copper mesh and raschig rings may be combined as packing materials.

Raschig rings are an economical and re-usable random packing material used in still’s columns to increase surface area while distributing your liquids more evenly. Furthermore, they’re cheap and easily re-useable!

Friedrich Raschig created the Raschig Ring as an effective distillation packing method in the early 1900s. Consisting of cylindrical metal or ceramic pieces of equal height and diameter arranged uniformly, when poured into a distillation tower these theoretical plates create multiple theoretical plates while decreasing hold-up (the amount of liquid remaining within the column).

As these cylinders are relatively small and boast a large surface area, they allow vapor/liquid contact between gases and liquids – an essential step when it comes to isolating volatile hydrocarbons. Furthermore, these units can also help isolate ethanol from water while simultaneously increasing phenol yield and purity as well as other chemical processing applications. Lastly, their resistance against abrasion, corrosion, chemical and solvent attacks as well as temperature shocks makes them suitable for everyday chemical processing needs.
