Ceramic Structured Packing
Series
of structured packing have been developed since 1972, applying in various
industries, e.g. chemical, petrochemical, fertilizer, fine chemicals
and environmental protection industries. Several patents of our
products or production were granted by national authorities.

Ceramic Structured
Packing |
|
Ceramic structured packing consists of many tiny packing units with the
same shape, ceramic ripple flakes, which are composed vertically
parallel to each other. Its external shape is often in cylinder unit or
cube unit.
Ceramic structured packing is also called Kelapak Packing. Due to
its high separation efficiency several times, even dozen times over
random packing, it’s also called High Efficiency Packing.
Because of unique ceramic structure and excellent hydrophile
performance, a paper-thin film of liquid can be formed on its surface.
It can
force fluids to take complicated paths through the column, thereby
creating a large surface area for contact between different phases.
With the characters of high
mechanical strength, high chemical stability, and long use life,
Ceramic Structured Packing can resist high temperature, acid
(except HF), alkali, salt and
various organic solvents.
It's widely applied in various packing
towers of desiccation, absorption, cooling, washing, and regeneration in
industries of petrochemical and chemical.

Advantage
Compared with plate tower or random packing, Ceramic Structured Packing
has excellent performance below:
-
Big flux. Applying structured packing, the tower diameter can be
narrowed for new designed tower and bigger handling capacity can be
reached for existing tower need to improve.
-
High separation efficiency. There will be much larger surface area
than random packing.
-
Low pressure drop. It can save more energy.
-
Flexible operation,
small Liquid holdup and small scale effect.
-
Suitable for all
tower diameters
|
|
Based
on difference of accumulation
obliquity,
there are two types structured packing, X type (30°) and Y type (45°).
Generally, X type structured packing has lower pressure drop and Y type
has better mass transfer efficiency. |
|
Application
-
Applicable
to separation processes, especially for corrosive or
thermal media. When the operating pressure is between 0.1 - 500 Kpa, the application performance is good.
-
Applicable to rectification process of halogenated organic
compounds.
-
Applicable to rectification or absorption process of
corrosive mixtures, which have strict requirements on pressure
drop and theoretical plate number.
-
Applicable to towers containing large quantity acidic media,
e.g. processes of sulfuric acid absorption, nitric acid
concentration and air purification in fertilizer plants
-
Applicable to operation under vacuum situation, at a bottom
absolute pressure of 100 pa.
