Raschig Rings For Heat Recovery

Raschig rings for heat recovery provide an effective means of increasing the efficiency of distillation and extraction processes. First developed by Friedrich Raschig in the 1880s, these tower packings allow an enhanced surface area between gas and liquid interactions – ideal for separation operations. Raschig rings have multiple uses such as distillation, separation, gas scrubbing as well as solvent recovery.

Their open structure reduces pressure drop and promotes effective mixing in a column, and they come in both ceramic and metal varieties to meet different application environments. Ceramic raschig rings offer excellent abrasion resistance and corrosion protection against acidic or alkaline environments while being thermally stable enough for harsher environments without suffering degradation or impairment.

Metal raschig rings are an effective choice for chemical separation processes that demand higher temperatures and mechanical strength, such as fractional distillation. Their durability makes them resistant to corrosion, slurries, salt solutions and organic compounds – proving popular as an option in high temperature separation processes like fractional distillation.

Graphite raschig rings have an ideal combination of low bulk density and open structure that allow liquid to pass freely through thousands of pathways to coat both inside and outside surfaces of the ring, leading to turbulent movement that encourages gas to mix with liquid for greater mass transfer efficiency. When used for gas scrubbing purposes these rings help remove pollutants or impurities by bringing it in contact with a liquid cleaning solution.
