Packing Elements / Edge deflector / Supports and support frames / Performance
In order to intensify the material transition in absorption, desorption, distillation and extraction columns structured packing from borosilicate glass 3.3 is used. They ensure high flow rates with low pressure loss and at the same time guarantee good separation.
DURAPACK® packing is comprised alternately of allocated glass corrugated plates in which the current channels slopes are 45°. In order to increase the turbulence the corrugations are notched. The packing is only made from Borosilicate glass 3.3, i.e. they are connected without glue so that only borosilicate glass comes in contact with the media to be processed.
The packing element
The packing elements are in one piece in the nominal bore from DN 100 to DN 300. The nominal width DN 450 is comprised of two half circular segments and can also be used on a support ring. Elements with a nominal width of DN 600 or more are divided into individual segments. A support frame is needed.

Edge deflector
DURAPACK® mass transfer packaging can be used both in glass columns and in columns made of other material such as enamel. In spherical glass receivers up to a nominal width of DN 1000 the outer diameter of the packaging is automatically adjusted to the column. With columns made of other materials the column-inner diameter must be given with the tolerance. To avoid wall effect on flow the elements are equipped with patented edge deflectors made of PTFE (in the delivery schedule) on the outside.
All packaging elements have a height of 200 mm. Up to a nominal width of DN 300 the packaging elements have two edge deflectors, from 300 one each. Flexible edge deflectors can be installed with glass packaging in standard column pipes. Precision pipes are not necessary.

Supports and support frames
DURAPACK® packing can be placed on a supporting ring with a maximum diameter of 450 mm. The following standard components are available for glass columns.
|
|
|
PTFE supporting ring
Available up to a nominal width of 300 and up to a
packing height of 1 m.
|
Supporting rings steel/PTFE
Available up to a nominal width of DN 450, up to a packing height of 3 m.
The supporting rings with a steel core can also be simultaneously used as a fixed point in the frame.
|
Steel/PTFE supporting ring with support frame
Available from DN 600 up to a nominal width of DN 1000 with a packing height of 2 m.
Since the support frame is confined to approx. 60% of the free cross-section of the columns, the CORE-TRAY should be used for high performance applications and for larger diameters.

Performance
DURAPACK® packing can be used for distillation as well as for extraction processes. The easy-to-clean smooth and inert surface is extremely convenient. The specific surface amounts to 300 m²/m³.

Performance for extraction columns
Since it must be avoided that the packing surfaces become wet from the mostly organic disperse phase during extraction, a glass packing with smooth, fire-polished surfaces are best suited for this. The extraction experiments have been carried out in a pulsed column with the test mixture toluene/acetone/water. During these experiments the flooding point was determined with an amplitude of 8 mm and a frequency of 100 min-1. The number of stages was measured with a load of 80, 60 and 40%.
