Graphite Raschig Rings Description
The shape of the Graphite Raschig Ring is a circular ring with the same outer diameter and height. It is made of high-purity colloidal graphite, with a simple shape, large specific surface area, good corrosion resistance (especially resistant to hydrofluoric acid corrosion), and its fluid dynamics and mass transfer characteristics are relatively clear, and it is widely used in highly corrosive media packed towers.

Graphite Raschig Rings Applications
Graphite Raschig Rings are used in crude oil refineries, petrochemical plants, and chemical plants. They are used in large numbers as a packed bed within columns for distillations and other chemical engineering processes.
Graphite raschig rings are chosen for their excellent resistance to corrosion, high-temperature stability, and durability in aggressive environments. Their unique structure provides a large surface area and good void space for effective mass transfer and heat exchange processes.
