Mott
sampling filter.
Series
8501 – threaded assembly.
Operating
principle as sampling filter.
The
gas or liquid to be sampled is introduced at the mainstream
inlet and accelerates as it passes the filter, due to the
reduced flow passage. This increased velocity puts the filter
into an inertial mode. Plugging is minimized, since particulate
matter in the mainstream is directed parallel to the filter
tube rather than incident to the porous media.
Filter
applications.
- Particulate-free
sampling.
- Liquid
analysis.
Advantages.
- High
differential pressure capability.
- Wide
range of porosities.
- Self-cleaning
for long on-stream life.
- Simple,
all stainless-steel assembly.
- Uniform
permeability.
Operating
principle as sparger or gas/liquid contactor.
Liquid
is introduced at the mainstream inlet and accelerates around
the porous element. Gas is injected at left, through the porous
tube, creating extremely fine bubbles. As these bubbles emerge
from the porous tube, they are continuously sheared by the
liquid – further reducing their size and increasing the
gas/liquid interface. Bubble size can be varied by adjusting
velocity. Higher velocities result in higher shear rates and
finer bubble size.
Sparger
applications.
- Carbonation,
aeration, hydrogenation.
- Injection
of air, oxygen, hydrogen or other gases for gas/liquid reactions.
Advantages.
- Uniform
permeability for consistent bubble size.
- Dynamic
reduction of bubble size for maximum efficiency.
- High
efficiency from bubble shear reduces sparger size required.
Standard
