Ceramic Structured Packing
Product No: TPU®-CSP
Question: What's special about ceramic structured packing?
Answer: 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
