ETech Nitrogen generators
WME manufactures on-site nitrogen generation systems utilizing
membrane air separation technology. These nitrogen generation
systems are used for inerting, blanketing, and purging of chemicals
and other cargos.
ETech membrane modules contain thousands of hair-like membranes that
collectively separate large amounts of high purity, dry nitrogen directly
from compressed air, which may be applied to prevent degradation of cargo
sensitive to oxygen, moisture or combustion by-products. The dry gas from
these systems are also ldeal as non-freezing, non-corrosive instrument gas,
and for drying of cofferdams.
Advantages:
• Low cost with on-site generation,
saves up to 50%
• Wide capacity range
• Dry nitrogen, dewpoint
@ atm. pressure 70°C
• Purity 95-99,9%
• Easy to install, operate and maintain.

Regeneration
The N2 generating plants
normally located in the engine
room consist of feed air
compressor, membrane filtering
unit, nitrogen buffer tank and
control/monitoring panel
including valve/fittings.
WME Marine Nitrogen systems
cover a wide range of capacities
and nitrogen purities. The
membrane based systems
generate clean, dry gaseous
nitrogen up to 99,9% purity from
compressed air.
ETech Offshore Nitrogen
systems cover a wide range
of capacities and nitrogen
purities. The membrane systems
generate clean, dry gaseous
nitrogen up to 99,9% purity from
compressed air.
WME may offer a method for regeneration of air-gas separation membranes, a technique which up until
now has not been available in the market.

ENG M
ETECH MEMBRANE
The nitrogen generating plant can serve
various purposes such as supply of nitrogen
gas into the insulation void spaces, for
purging of fuel gas line in engine room,
for purging of cargo liquid line, vapor line,
gas line, vent masts and related cargo
equipment as well as for sealing of the
penetration shaft and shaft seal of high duty
and low duty compressors. The insulation
void spaces normally is to be pressurized/
maintained by nitrogen vapor from the
nitrogen generator and vented to the
atmosphere through vent control valves.
The ENG M systems (designed for Chemical
tankers) and ENG systems (designed for
Offshore supply vessels) consist of free
standing feed air compressors and fully
automated Nitrogen generation units.
The latest PLC systems are applied for
control of product qualities and for signal
output to ship integrated control systems.
Product purity is automatically monitored
and controlled. If the product purity is not
maintained, the generated nitrogen will be
vented automatically.
The ETech membrane systems has a high
capacity to weight relationship compared
with other non-cryogenic sources.
Etech membrane systems are relatively
lightweight and compact, enabling them to
fit into places where space is limited. The
systems are portable, stand alone units that
require only supply of dry, compressed air.
These computerized, automated process
control systems are an ideal choice for
applications requiring purities up to 99,9%,
as well as extremely precise control
capability, data logging, or remote operation
and communication. These systems can be
applied within a wide capacity range.
Membrane produced nitrogen can be
supplied over a wide range of purities.
Modular system design allows for system
expansion with the addition of modules,
increasing nitrogen capacity as your
requirements change. System layouts can
be configurated to meet the most unique
site requirements.
For years it has been a well-known
problem that membranes may often
be exposed to contamination, and as
a consequence will become deficient
in terms of performance. Air-gas
separation membranes are sensitive
to contaminations from hydrocarbon
aerosols/liquid (i.e. oil products) in
the sense that such contamination
cannot be removed nor can the
membrane be regenerated, without
running the risk of destroying
the membrane. Most membrane
based nitrogen generators have
traditionally been equipped with oil
lubricated feed air compressors,
which increases the risk of oil
contamination of the membranes.
Traditionally, this problem has been
dealt with by applying traditional
filtration techniques upstream the
membrane. These techniques,
combined with increasing the feed
air temperature after filtration,
results in a gap between the actual
temperature of oil and water vapor
versus dew point temperature of
these, thus avoiding condensation
of vapor. Even though filtration
equipment is installed, there
will always be a risk of oil vapor
carryover into the membrane. One
of the situations that may contribute
to this risk is that the traditional
air-gas separation membrane
normally has a recommended
max. operating temperature of 50
°C. The compressor cooling water
available may have a temperature
of 36 °C, which, owing to the feed
air temperature rise across the
compressor, may result in a feed air
temperature of as much as 46 °C,
prior to the temperature increase
required to avoid vapor condensation.
This leaves us with a temperature
gap of only 6 °C, which is not enough
to avoid vapor condensation, because
there is a temperature drop higher
that this across the membrane,
during the separation process.
With the new ETech membranes,
these problems are avoided,
because, at first, the membrane
material, polyamide, consists of
a single composition, and not, as
many other membranes, a dual
composition, where the governing
membrane is a thin layer applied
on to a substructure. The two layers
are normally of different materials.
The polyamide may withstand a
much higher temperature (typically
as much as 130 °C), and may
easily operate at a temperature
of 60 °C, thus avoiding the risk of
vapor condensation owing to lower
operating temperatures. If however,
there should be a vapor carryover,
due to filtration failure or excess
oil carryover from compressor,
then the ETech membranes may be
regenerated. WME can therefore
offer an exchange arrangement,
provided that ETech membranes
are already installed. It is quite
apparent, the cost savings in such
an arrangement, as opposed to
purchasing brand new membranes.
The Life Cycle Cost of Nitrogen
generators can be reduced with
as much as 60% compared to a
normal membrane set up, and will
also contribute to increased safety,
in terms of regularity and system
capacity.
LGP
The nitrogen generating plant can serve
various purposes such as supply of nitrogen
gas into the insulation void spaces, for
purging of fuel gas line in engine room,
for purging of cargo liquid line, vapor line,
gas line, vent masts and related cargo
equipment as well as for sealing of the
penetration shaft and shaft seal of high duty
and low duty compressors. The insulation
void spaces normally is to be pressurized/
maintained by nitrogen vapor from the
nitrogen generator and vented to the
atmosphere through vent control valves.
WME Marine Nitrogen systems are based
on modular design principles. Membrane
modules can be added or replaced in order
to upgrade the system in rated capacity
after initial installation. This design
principle allows for system expendability,
in most cases without the need of
replacing the existing system. Furthermore
light weight and compact design of the
membranes allow us to transport and
install the Nitrogen systems easily to a wide
range of process application and in various
locations and conditions.
