Ceramic Structured Packing
Product description
Ceramic Corrugated Structured Packing is also called kelapak. It is composed of many packing units with the same geometric shapes. Each packing unit consists of parallel superposed corrugated sheets. Ceramic structured packing has high efficiency, low pressure drop, high capacity; scale effect is not obvious, high operating elasticity, corrosion resistance, heat resistance etc.
Ceramic Corrugated Structured Packing can widely used in the drying tower, absorbing tower, cooling tower, desulphurization towers, rectifying tower, washing tower, coal gas scrubbing tower, coking scrubbing benzene tower, scrubbing NH3 tower, ammonia washing tower,naphthalene washing tower, fertilizer saturation-heat water column and scrubbing tower, fertilizer heat gas saturation tower and regenerative tower.
With a unique structure,and excellent hydrophilic performance, the very thin liquid film can be formed in the surface of ceramic,and the flow of liquid film as well as oblique and flexural channel ensure the smooth airflow , and dont impede it,making the efficiency of this product comparable with metallic corrugated packing. Dohntec makes the production of different specific surface area and flexible standard structured packing in terms of customer's demands.
Ceramic structured packing is not only widely used in coal gas washing tower, fertilizer heat gas saturation tower, naphthalene washing tower, ammonia washing tower, but also as the support for heat exchange machine , catalyst, and suit for a big tower rebuilding/revamp.
Typical Application
100X
The feature of high corrosion resistance makes it specially suitable for refinery of oil with high acid value, protecting naphthenic acid from corrosion. It is a good choice for desulfurization apparatus and towers.
250X,Y
Widely used in the process of separation for mineral brine lixiviant reactant mixture, rectification for organic acid solutions as well as absorption / desorption for vitriol medium .
350X,Y
Widely used in the acid dehydrator to reduce reflux, increase acetic acid and lower column operation temperature. Excellent separation performance for the process of high vacuum decompression , its ideal high temperature and corrosion resistant packing material for the glass, glass fibre reinforced plastic and enamel tower.
450X,Y
Widely used in absorption, desorption, separation of rectification for corrosion mixture, requiring the theoretical plate 4-5, economic loading range: F factor 1.5-2.
700 X
Specially designed for the high mass-transfer efficiency rectification towers. Dohntec suggest a support grid should be installed every 3 to 4 meters height of this structured packing.
