Marine & Shipyard

Munters provides designs and engineering solutions for the following Marine industries:
Munters marine mist eliminators allow the engines to breathe unrestricted while at the same time effectively removing
the salt content of the air. Every type of pleasure boat and boating environment is catered for, from the calmest inshore
waters with low saline content right up to extreme conditions. Yet the mist eliminator units are unobtrusive, blending in
smoothly with the outer surfaces of both modern and classical boat designs. Munters’ units are suitable both for
newbuilds and also for retrofitting. You scarcely notice them as they look like an integral functioning part of the overall
vessel design – and that’s exactly what they are!

Breathe easy!

The secret of the technology lies in preventing water and especially salt water from entering, while still ensuring efficient
aspiration for the engines and the air conditioning at all times. And when the engines
breathe easily, they perform effortlessly, optimizing fuel consumption, performance and extending service life.

Air in, water out – how do we do it?

The principle of the mist eliminator is ingeniously simple and simply ingenious. Air entering the mist eliminator has to
pass through precision-engineered profiles. As the moisture-laden air impinges on the profiles, the droplets coalesce
and form a liquid film that is heavier than the air. This liquid drops down the profiles into drainage channels. The exact
size, shape and angle of the eliminator ensure that the liquid is separated without causing unacceptable pressure loss.
The technology of mist elimination pioneered by Munters has been extensively used throughout the industry for nearly
half a century and its application in boatbuilding has been widely adopted by designers and builders for decades.

Ready to fit marine mist eliminators

Munters’ range of marine mist eliminators addresses the whole range of pleasure boat applications, from freshwater
and inshore usage right up to extreme green water conditions with high salt, sand and contaminant content.

applications, for example: air intakes, condensate removal
behind cooling coils, as an air straightener before spray
humidifiers, in air washers etc. The unit is suitable for use at
face velocities between 2 and 6 m/s. The streamlined
separator deflects the droplet laden gas stream; as a result
the momentum of the droplets causes them to impinge
onto the profile surface. The droplets coalesce together and
form a liquid film; the influence of gravity causes the liquid
to drain to the bottom of the profiles. Specially shaped
separation chambers improve performance by enhancing
the separation of finer droplets and ensuring problem free
discharge of liquid. To avoid “flooding” of the profiles and
the possibility of re-entrainment of the separated liquid, the
height of the profile sections of droplet separators is
normally limited to 2,500 mm

Power

Mist Eliminators for Flue Gas Desulphurization

Munters Mist Eliminators helps anywhere liquids and gases need to be separated.
Environmentally hazardous emissions can be sharply reduced by cleaning flue gases from coal power plants. The
desulfurization process takes place in a process tower where flue gases pass before they are emitted out through the
plant’s chimneys. The contaminated flue gases are first sprayed with a mixture of water and chemicals that bind
contaminants.
Mist elimination also includes a cleaning system where contaminated water and sledge can be removed from the mist
eliminators, thus keeping them clean for greatest efficiency. Cleaning via desulfurization is very efficient. More than 95%
of the contaminating substances are eliminated in this process.
Mist elimination is a critical part of this process. Eventus, is in partnership with Munters, top tier Mist Eliminator
Manufacturer who have worked with leading power companies for decades and built up an extensive parameter
database with testing and follow-up processes, and a design tool that adapts and optimizes results based on customer
conditions.

Getting it right – First time

How mist elimination works in FGD
Exhaust flue gas is de-dusted and then it passes through
the absorber where it is washed with a suspension of for
example limestone in water or sea water. Acidic
compounds in the exhaust gases react with this
suspension. The SO2 is absorbed into slurry droplets
containing calcium sulphite that is then partly oxidized into
gypsum.
The cleaned gas passes through while the mist eliminator
stops the liquid droplets from escaping into the
atmosphere. Gypsum is a valuable byproduct of this
process and it can be reclaimed and used, for example, by
the construction industry.

The mist eliminators themselves are precisionengineered
systems containing vanes that divert the gas
flow passing through them. As the gas impacts with
the vanes, the droplets entrained in the gas coalesce
into a liquid layer which drains downwards
through the force of gravity.
The principle is very simple, but miscalculation
or using an inappropriate mist eliminator can result
in excessive pressure loss (energy costs) with impact
on performance or in excessive carry-over and
inefficient cleaning. Yet with the right expertise you
can achieve significant benefits while also being
certain that use of flushing water is optimized and
space and engineering costs are kept to a minimum.
Mist eliminators can be installed in layers and
in vertical or horizontal configurations depending
on the design of the absorber.

Horizontal flow configurations
In horizontal flow applications you can use frame
or panel designs.
Designs
The mist eliminator system (DH2100-FGD) is
typically installed in the exhaust duct directly
downstream of the spray system. Horizontal flow
configurations accommodate higher gas velocities
than vertical flow. The horizontal flow installation
requires less surface area while still achieving excellent
efficiency

Vertical flow configurations
In vertical configurations you can use flat- or roofdesigns,
or a combination of both.
Flat designs
Munters’ DV880 is a flat design panel system that is
particularly suitable for use in towers with lower to medium
gas velocities. It is built into the head of the absorber tower
and comprises individual sections resting on parallel
support beams and a surrounding wall support. Separated
liquid falls directly back into the sump of the absorber.
Munters’ DV880 can be installed as either double or triple
stage systems.

Roof designs
Munters’ DV210+ is a roof type mist eliminator that is
installed in any of three different ways. It has been
specifically esigned to address the increasing demands on
high efficiency mist elimination. The system includes an
integrated online cleaning system to ensure optimal
performance in cases where plugging or scaling of the
vane surface is a risk.
Munters’ DV210+ systems are installed in the top section of
the absorber tower. With d esign III, a single support beam
can be employed, reducing investment cost and height
requirements.

V Shape Mist Eliminators:

V-shaped vane type separator system for vertical gas flows. The system is typically used in gas cleaning devices such
as flue gas desulphurization absorbers and wet scrubbers. They have been specifically designed to address the
increasing performance demands of high efficiency mist eliminators. The system comes with an integrated online
cleaning system used in processes that could cause plugging and scaling on the vane surface. The system is designed
for a single, 2 or 3-stages with several cleaning layers depending on the specified liquid rest content and the operating
conditions.

Washing systems are completely integrated to the V-Shape modules, thus no separate support structure for the
washing system is needed. For application with high cleaning requirements the V-Shape module is equipped with both
upstream and downstream cleaning devices. Eventus’ top tier partner supplies beside performance guarantees data
for cleaning cycles, water consumption, nozzle and pump data and peripheral data for integrating the system into the
absorbers/scrubber structure.

GAS – LIQUID SEPERATION

Throughout many chemical processes, liquid-gas separation plays a vital role in recovering lost product or in protecting downstream equipment and processes from droplets in the gas stream. These droplets could be impurities in the gas phase, caused by condensation during cooling or they are simply caused by high gas velocities resulting in liquid carry-over.

In every case, efficient separation, designed specifically for the job in hand, will save money through recovery of product, enhanced process efficiency and/or reduced wear and damage to equipment. Solutions include customized liquid-gas separation equipment and demisters for horizontal and vertical flow in the following applications:

• Sulphur separation in Claus plants
• Separation of methanol from acid gas
• Synthesis gas droplet separators for Ammonia plants
• Condensate separators for nitric and phosphoric acid plants
• Cracked gas suction drums for Propylene / Ethylene production
• Natural gas and Syngas KO Drums
• Multiple stages KO Drums for liquid slugs at the well head including sand and solid particles using i.e.
  filter cartridges and vane sections
• Natural gas liquid extraction and glycol dehydration
