Wire mesh packing 500X SS316L in pharmaceutical equipment pilot
plant
1. factory of wire mesh packing supply range:
In factory, we produce and supply wire mesh structured packing /
wire gauze tower packing. The material available includes ss304,
ss316L, Titanium, copper, etc.. We can make most of the popular
types of wire gauze packing, like 250Y, 500X, 700Y, etc. The shape
and size can be customized as per order. So as the packing layer
height. If needed, the wire size can be customized, too. Welcome
your inquiry!
2. Pressure drop calculation of packed tower wire mesh packing,
When the pressure drop of the whole column is greater than the
allowable value, the diameter of the column must be enlarged or the
type and specification of the selected packing must be changed.
The pressure drop of the whole tower includes two parts: the
pressure drop of packing layer and the resistance of tower
internals. There is always a certain gap between the calculated
pressure drop and the actual production, especially the dirt in the
packing layer, the crushing of ceramic filler and the thermal
deformation of plastic filler will greatly increase the pressure
drop of packing layer. Therefore, a certain safety factor should be
introduced into the calculated value.

4. wire mesh packing layer height determination.
Generally, the mass transfer unit method or theoretical plate
number method is used to calculate the total height of packing
layer Z
Z = HTU * NTU = holnol = hognog or Z = HETP * nt
Theoretically, the two-phase concentration in packed tower changes
continuously along the tower height, which belongs to continuous
(differential contact) mass transfer equipment. Therefore, it is
reasonable to use mass transfer unit method to calculate the
packing height. However, in some engineering fields (distillation,
hydrocarbon absorption, etc.), theoretical calculation is used.
Computer software and HETP data for calculating the number of
theoretical plates are provided.
There will be some discrepancies between the calculated height of
packing layer and the actual needs of production due to the fact
that there will be some discrepancies between the calculated
packing layer height and the actual production requirements (such
as balance data, physical property data, mass transfer coefficient
or hog, HETP, etc.). In order to ensure the safety of production
needs, but also in order to make the production fluctuations when
there is appropriate room for adjustment, so the actual use of
filler height must also add a safety factor.
Z actual = (1.3-1.5) Z calculation.
