Dixon Ring, it was successfully developed by British scientist O.G. Dixon in 1949 and derived from Raschig ring packing.
It is mainly used in the rectification separation process of laboratory and small batch, high-purity products, as well as the separation of stable isotopes and laboratory-scale isotope development.
It is made of 60-100 mesh metal wire mesh rolls, with the same diameter and height. Common materials include stainless steel, copper, etc. Due to the capillary action of the metal wire mesh, the liquid can be well dispersed to form a film, which is conducive to the full mass and heat transfer of gas and liquid, and can significantly eliminate instability such as channeling. Under stable operating conditions, the number of theoretical plates can reach 30 per meter, which is one of the commonly used laboratory bulk fillers in the laboratory.
Product specifications:
(diameter×height, mm) 2×2, 3×3, 4×4, 5×5, 5×5 (double layer), 6×6 (double layer), 10×10 (double layer), etc. ,
Customized specifications ≤25×25mm,
of which the most used specification is 3×3mm, and the number of theoretical plates per meter is about 20, which is much higher than structured packing.
The quality of the mesh ring packing produced by our factory is checked layer by layer,

Product Description
Dixon ring packing also known as θ ring packing is a kind of small particles and high efficient packing, it is made of metal wire with uniform diameter and height.
Application: Dixon ring packing is used mainly for laboratory and small batch, high-purity product separation process.
Product Advantage
The pressure drop of packing is related with gas velocity, liquid spray quantity, material, surface tension, viscosity, the characteristics of the packing, and the flooding capacity at the same time. Dixon packing of hysteresis is higher than the similar entity packing, surface wetting condition is better than general porcelain ring too, thus its film formation rate is higher, and separation efficiency is also higher. The theoretical plate number of Dixon packing is increased with the increase of gas velocity, and at the same time, lower with reducing of the surface wetting rate of packing.
