Ceramic surface can generate extremely thin film liquid flow and tortuous vapor flow passages promote mixing of liquid and vapor and, at the same time, general little pressure drop. These are reasons for Ceramic Structured Packing have the same mass transfer efficiency as metal packing. Meanwhile, Ceramic Structured Packings are much more resistant to corrosion and high temperature than metal packing. The surface structure of ceramic packing could promote wetting and keep liquid hold-up to a minimum.
Ceramic Structured Packing (Ceramic Corrugated structured column packing) is constructed of corrugated sheets of ceramic. 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.
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. (Data for our products follows: X and Y stand for the corrugation dip of 30 and 45 respectively; the Arabic numerals stand for the specific area of their series.
Advantage of Ceramic Structured Packing:
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.
Application of Ceramic Structured Packing:
v Fining process of corrosive mixtures, which have strict requirements for pressure drop and number of theoretical sheets
v Vacuum treatment under absolute pressure higher than1m bar
v Fining and distillation of halogen organic compounds. Rectifying organic halide
v Rectifying and absorbing some corrosive mixtures, which are definitely regulated in pressure drop and theoretic plate number
v 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
v Operating in vacuum conditions at a bottom absolute pressure of 100pa
v Used in heat exchanger and demisting, or as a catalyst carrier
