Customzied Ceramic Structured Packings , High Capacity Distillation Column Internals
Ceramic Structured Packings, a very thin liquid film can be formed on the ceramic surface. Turbulence of the liquid film and the oblique winding gas channel can promote vapor instead of stopping it, therefore separation efficiency of the packing is equal to that of metal corrugated-sheet packing. Surface structure of the ceramic packing has good wetting ability, which promotes liquid flow and minimizes liquid holdup, as a result, the opportunity of superheating, polymerization and coking reduces.
Excellent Performance:
1. High capacity. New tower design may reduce diameter, while revamping old towers may increase capacity significantly.
2. High separation efficiency owing to much larger specific surface area compared with random packing.
3. Low pressure drop, which leads to reduce energy consumption largely.
4. Large flexibility, and scale effect is not obvious.
5. Applicable to all tower diameters.
6. Strong resistance to corrosion of acid and alkali, especially to H2S, naphthenic acid and Cl-.

Detailed description of each type of product:
1. 700Y,500Y
The filler has low resistance, high efficiency, large separation capacity, and can replace other fillers or partial plate towers under certain conditions.
Product Features:
a. Large specific surface area and large porosity;
b. The gas phase passage has a small inclination angle, regularity and pressure reduction;
c. Radial diffusion is good and gas contact is sufficient.
Applicable occasions:
500Y (X): vacuum rectification which is heat sensitive and difficult to separate, especially vacuum distillation with a pressure less than 7 KPa, atmospheric distillation.
700Y (X): separation of isotopic mixtures, isomeric mixtures.
2. 450Y,450X
It is used for precision fractionation with high requirements on the mass transfer efficiency of the tower. It is especially suitable for chemical production processes such as acetic acid, methanol and styrene, and separation of high-purity fine chemical products. The adaptation conditions are roughly as follows:
Gas phase load factor, F=1.5~3(m/s)[Kg.m3]1/2
Minimum liquid load, L (spray density) ≥ 2m3 / m2.h
3. 350Y,300Y,250Y
The product combines the two main properties of pressure drop and efficiency in the mass transfer process. Especially suitable for atmospheric pressure in the refining process.
Application:
1.Separation of chloroacetic acid / dichloroacetic acid / acetic acid / acetic anhydride between room temperature and 1400℃
2.Separation of aromatic chloride, lipoid, hydrocarbon and other highly thermosensitive systems and isomeric compound in vacuum under 1 mbar,.
3.Regeneration of organic solvent contaminated by hydrochloric acid/ sulfuric acid/ nitric acid/ hydrogen phosphide / hydrogen bromide / bromine, etc.
