ANALYTICAL SIZING OF A WIRE MESH DEMISTER -
known wire mesh demisters can supply high efficiency of separation
(it's common to separate droplets till 3 microns of diameter) with
low pressure drop but, to obtain the best performances, it's very
important a proper sizing of the separators. Thanks to AFP ProCalcDem,
our analytical method of calculation, and on the base of process
conditions and fluids caracteristichs we supply to our customers
two different services:
- checking of a old wire mesh separator: the customer
supplies us the process datasheet and the features of the separator.
On that base our technical office checks efficiency and pressure
drop of the process and the dimensions of the separator.
- sizing of a new separator: the customer, giving us the
process datasheet, needs to define the type of separator and its
dimensions to obtain the requested efficiency, the right pressure
drop satisfying some dimensional limits as well.
On the base of our calculation, if it's necessary, we can suggest
changing at the separators or at the vessel or confirm what was
defined in the datasheet. Moreover we can supply an official document
where we describe the process efficiency in terms of limit of separation
and pressure drop at the process conditions.
VANE PACK SIMULATION -
best approach at the vane pack sizing is nowadays the simulation
of the gas flow made with a model. Through this method it's possible
to see what really happens inside the pack during the process studying
the particles tracking and the behaviour of the flow.
In this way it's possible to choose, customize and optimize the
kind of the vane pack being sure about the achievement of the performances
reducing costs as well.

- COMPARISION OF DIFFERENT CONDITIONS -
very interesting opportunity and another service we can supply
to our customers is the comparison of different work conditions
for the same saparator.

Making some computing cycles we can study different situations
identifying the best conditions in term of process efficiency
and pressure drop with great advantagies in terms of process efficiency
and cost savings.
