Raschig rings, the first random packing developed, are small tube cutouts with an outer diameter equal to their height that provide a surface for (re)evaporation of the most volatile fractions in the reflux fraction. It has high mechanical strength, high chemical stability, and excellent heat resistance. For large Raschig rings with a size of more than 100 mm, they are usually arranged in an orderly manner. If its size is less than 90mm, the Raschig rings are randomly stacked in columns. It has excellent corrosion resistance to various inorganic acids, organic acids and organic solvents other than hydrofluoric acid, and is widely used in various acid corrosion production. Such as drying towers, absorption towers, cooling towers, washing towers, activation towers, etc. in chemical industry, metallurgy, gas, oxygen production and other industries.
is the earliest generation of random packing. The height and diameter of ceramic raschig ring is same and the common specifications are 25 mm to 76 mm.
