A raschig ring is a fundamental type of tower packing, a critical component in tower internals, widely applied across chemical processing industries. Invented by Fritz Raschig in 1914, this packing features a simple cylindrical structure with equal height and diameter, typically made from materials like stainless steel, polypropylene (PP), polyvinyl chloride (PVC), or ceramics. Its basic design—an open, hollow cylinder—enables efficient fluid distribution and gas-liquid contact, making it a cornerstone in separation processes such as distillation, absorption, and extraction.

As a core element of tower internals, Raschig Ring packing operates by balancing two key factors: low pressure drop and favorable mass transfer efficiency. The hollow structure allows fluids to flow freely through the ring and around its surface, minimizing resistance to gas or liquid flow while maximizing the contact area between phases. This balance makes it particularly suitable for small to medium-scale industrial applications, including petrochemical refineries, environmental treatment plants, and pharmaceutical production, where reliable separation and durability are paramount.
