Dixon ring is a small particle high-efficiency filler, made of wire mesh, the diameter of the filler is equal to the height. The dixon ring packing is mainly used in the laboratory and the separation process of small batch, high purity products. The pressure drop of the dixon ring packing is related to the gas velocity, the amount of liquid spraying, the weight of the material system, the surface tension, the viscosity, and the characteristic factors of the packing, as well as the pre-flooding treatment of the packing. The stagnation amount of the Dixon ring packing is larger than that of the same kind of solid packing, the surface wetting of the dixon ring is also more complete than that of the general ceramic ring, and the film forming rate is higher, so the efficiency is also higher. The theoretical plate number of theta ring packing increases with the gas velocity and decreases with the decrease of the surface wettability of the packing.

Specification

Features:

1.Ultra-high separation efficiency: The theoretical plate number is significantly higher than that of Raschig rings and Pall rings;
2.High liquid-holding capacity: suitable for precision separation and low-volume processing conditions;
3.Applicable to small tower diameters: suitable for small distillation columns with diameters ranging from φ20 to 200mm;

Application:
1. Laboratory/University Research 
Small glass distillation column, precision distillation device; Purification of organic reagents, solvent separation (high-purity distillation of ethanol, ethyl acetate, methanol, etc.).
2. Isotope special separation (high-end scenario)
Tritium/water separation, stable isotope purification; Difficult to separate operating conditions with boiling points very close to the system (high-precision specialty chemicals).
3. Fine chemical small-scale high-purity production
Pharmaceutical intermediates, essence and fragrances, high-purity monomer, electronic solvent distillation purification.
4. Absorption/exhaust gas treatment (niche)
Small countercurrent absorption tower, acid gas removal, laboratory carbon capture, trace harmful gas washing and purification.
5. Equipment renovation and refurbishment
When the original packing separation accuracy is insufficient, replacing the Dixon ring inside the tower can improve the separation effect without replacing the tower equipment.
