250Y 350Y 500Y 700Y Ceramic Corrugated-Plate Structured Packing
Ceramic structured packing has similar structure with grid structured packing, which is composed of several smooth surface corrugated sheets in 60° or 45°. The angle of inclination of the corrugations of adjacent sheets is reversed with respect to the vertical column axis, forming mixing cells at every point where the corrugation intersect.
This promotes intimate mixing and radial distribution of the liquid and gas streams. Each subsequent element is rotated about the column axis so that the sheets of one element are opposed to the sheets of the elements above and below. In passing through each element, gas and liquid are thoroughly mixed in the direction parallel to the plane of the sheets. By rotating subsequent elements, excellent mixing and spreading, both side to side and front to back are obtained over the entire cross section of the tower.
Compared with metal structured packing, the ceramic structured packing has better corrosion and rust resistance performance and high temperature resistance performance than metal structured packing. The flow characteristics developed by the structured geometrical arrangement creates high effective surface area resulting in good efficiency as compared to other mass transfer devices.
Additional, ceramic structured packing has high separating efficiency, low pressure drop, increased operating elasticity and maximum liquid treatment.

Ceramic Structured Packing Features
v The most economical range is F-factor1.5-2
v Improve capacity by up to 50% over standard ceramic saddle Column packing
v Excellent Resistance to Plugging
v Improve efficiency up to 25% over standard ceramic saddle Column packing
v Greater Heat Recovery in RTO Applications than any Random Packing
v The corrugated sheets of ceramic are vertically oriented in the packed Column, eliminating any horizontal surfaces which create resistance to fluid flow
v Pressure drop of each theoretical sheet is 0.3-1mbar Lower pressure drop by 60% or more over standard ceramic saddle Column packing
v Ceramic Structured Column Packing geometric construction greatly reduces the channeling of both the liquid and vapor and provides for more effective contact of sulfuric acid and SO3 gas.
Ceramic Structured Packing Application
» Rectify organic halide.
» Rectify and absorb some corrosive mixtures.
» Absorb nitric acid and concentrated sulfuric acid and purify the chemical air.
» Used as catalyst carrier in heat exchanger.
