What is raschi rings?

Raschig rings are a type of random packing material used in chemical processing industries such as distillation, absorption, and stripping columns. They are named after the German chemist Friedrich Raschig who invented them in 1914.

Raschig rings are typically made of ceramic, metal, or plastic and come in various sizes and shapes. They are characterized by their cylindrical shape with a length equal to their diameter, giving them a uniform appearance. This shape helps to promote an even distribution of gas and liquid flow through the packing material, allowing for efficient mass transfer processes.

Raschig rings are commonly used for applications where high surface area is needed for mass transfer, such as in scrubbers, strippers, and fractionating columns. They provide a large surface area for contact between gas and liquid phases, allowing for efficient separation and transfer of components.

Overall, Raschig rings are a versatile and effective packing material widely used in chemical processing industries for various mass transfer applications.
