Munters Mist Eliminators
The Experts
in Mist Eliminator Technologies
As far back as
1966 Munters developed their sophisticated and highly efficient mist eliminator
profiles. These designs are based around a sinusoidal wave shape to which a
hook section is attached to enhance its performance. Since that time, this type
of mist eliminator, for use in horizontal gas flows, has been specified and
installed around the world under the "Euroform" name. It has become
the industry standard for mist elimination in the pulp and paper industry in
USA, Canada and Scandinavia, sugar evaporators in the UK, Belgium and France,
gas cleaning towers in Europe or Japan and process gas handling in Germany,
Australia or Malaysia. When high performance is crucial, our "Vane type
systems with hooks" are specified and installed.
Following this
success, Munters also developed mist eliminators for vertical gas flow. Their
DV 270, since 1970 their standard systems for gas scrubbing systems, has been
adopted as the basic design concept for most other "two-pass
eliminators".
To help you
evaluate the performance of various mist eliminator designs with regard to
limit drop sizes - even for competitors designs - advice can be offered. The
calculations or physical modelling can be provided for various operating
conditions and different vane designs.
Based on Munters
continuous research and development and their long-term experience in mist
elimination technologies, they have evolved a wide range of mist eliminator
types, each with specific modifications to suit individual application
requirements.
How do Munters Euroform mist eliminators function?
Munters
Euroform mist eliminators are vane type systems.
The specially
designed vanes form small channels with right angle gas paths when assembled
together into eliminator modules.
The sharp
changes in direction enforced on the gas stream in such a channel, produce
"inertial forces" that effect the entrained droplets. The droplets
are thrown out of the gas stream by these inertial forces and impact against
the outer wall of the channel, forming a liquid film on the channel wall. This
film then drains by gravity to a collection sump or back into the vessel.
To obtain
optimum efficiency, complete drainage of eliminated liquid, even at high gas
velocity and low-pressure drop, is necessary. Only a sophisticated, "high
tech" vane design (e.g. with sinusoidal-shape and hooks) can provide this.
Where are
mist eliminators employed?
In most
chemical or petrochemical applications, process gas streams contain various
droplets. They are either caused by condensation, e.g. after cooling processes,
generated by liquid injection in absorption or gas scrubbing processes; or by
carry-over in evaporator processes.
To eliminate
the predominantly very small droplets inherent in these processes, highly
efficient mist eliminator systems are crucially important. They will help to:
1 Optimise
chemical and petrochemical processes by elimination of undesirable liquids.
1 Prevent pollution of condensates after evaporator stations.
1 Recover
valuable liquid droplets in recycling processes.
1 Restrict
emissions from pollution control processes like scrubber systems, flue gas
desulphurisation installations.
1 Prevent
corrosion and erosion of gas turbines, air inlets and compressor stations.
For all these
applications Munters Euroform vane type separators are used and acknowledged as
"state of the art" technologies.
What can Munters Euroform provide?
For all
important applications Munters offer will be based on a study of plant or
process requirements and a detailed specific engineering proposal produced.
For existing
towers or casings Munters Euroform can supply a complete mist eliminator
package consisting of the vanes assembled into a suitable cassette or frame,
ready for installation.
Our manufacturing capabilities also include the supply of complete separator
systems including the housing, casing or vessel, for flange to flange
connections to ductwork or pipelines.
For common
applications and conditions we supply standardised packages and designs.
Munters
Euroform offers a broad range of materials, including various plastic types
like PVC, polypropylene, PVDF, Ryton and Ultem, plus metals such as aluminium,
carbon steel and high grade materials like Monel and Incoloy or other exotic
alloys.
