Ceramic Structured Packing

1. Description:

 

Ceramic structured packing of Pingxiang Chemshun Ceramics co.,ltd is a new type of structured packing, which is composed of many packing units with the same geometry. Due to the unique structure of ceramics, with good hydrophilic properties, its surface can form a very thin liquid film turbulence and the flow of the inclined and tortuous channel can promote the flow but it does not block the flow of the ceramic filler.

 

Chemshun structured ceramic packing in term of the corrosion resistance and high temperature resistance, the metal filler is not comparable. The surface structure has good wetting performance, which can accelerate the flow of liquid and minimize the amount of stagnant liquid in the packing. This reduces the chance of overheating, polymerization and coking.

This product is made of high quality chemical raw material of porcelain clay, which can withstand high temperature and high pressure, It has good chemical stability and high strength, and is an ideal carrier for supporting various types of catalysts.

2. Application of Chemshun Ceramic Structured Packings
1) Rectifying organic halide.
2) Rectifying and absorbing some corrosive mixtures, which are definitely regulated in pressure drop and theoretic plate number.
3) Applied in some towers that contain a large quantity of natural media used to absorb nitric acid and concentrated sulfuric acid, as well as for purifying the air in chemical plants.
4) Operating in vacuum conditions at a bottom absolute pressure of 100pa.
5) Used in heat exchanger and demisting, or as a catalyst carrier

 

4.Feature


 1) High capacity. New tower design may reduce diameter, while renovate old towers may increase capacity significantly.
2) High separation efficiency. Since it has much larger specific surface area compared to random packing.
3) Low pressure drop, which leads to reduce energy consumption largely.
4) Large flexibility, and scale effect is not obvious.
5) Suitable for all tower diameters.
6) Strong resistance to corrosion of acid and alkali, especially to H2S, naphthenic acid and Clˉ

 

5.Product process

 

1) Formulation of raw materials: Grind Kaolin into small particles, Mix essential materials and Kaolin in the process according to a certain ratio,remove the impurity through squeezing,crushing,ball-milling, and form the raw material of ceramic body by vacuum pug.

2)Manufacture of ceramic body:Press the ceramic body in customized mould,then adjust the semi-product for smooth surface without defects, Lay them flat and dry them until their water content up to less than 2%.

3) Assembly of the ceramic blank: the ceramic ripples between the adjacent ceramic blanks cross 90 angle,combine the adjacent crests by water glass binder in a structured shape.

4) Sintering and Production:burn the ceramic blank in kiln from 300℃ to 950℃, then preserve them warm and cool them down, then the finished products come out.
