To address the growing complexity of
air pollution regulations, which have
to address a multi-tiered array of local
authority, national and international
requirements, AirProtekt of Cambridge,
UK, is offering a total package air
pollution service that embraces process
assessment, project design, supply of
the air pollution equipment, installation
and commissioning.
Many air pollution applications call
for flexible abatement systems to be
designed and deployed, especially
where there is a requirement for batch-
based production runs. Low running
costs together with the ability to run the
abatement at low process flow rates are
vital. A quick start up system also offers
major benefits.
AirProtekt’s flexible package approach
to providing engineering solutions
means that the company is capable
of combining and tailoring modular
equipment to meet exacting air pollution
requirements in a cost-effective way.
For the majority of abatement
applications catalytic oxidation is more
expensive than thermal oxidation at
low flow rates. However, the reverse
is often the case for high flow rates.
Thermal oxidation abatement solutions
tend to be more economical at very high
VOC concentrations whereas catalytic
oxidation is typically more economical at
moderate VOC concentrations.
AirProtekt recognises that no two appli-
cations are the same, and each requires
careful assessment before a value for
money solution can be implemented.
For example, although an alternative
solution to a catalytic oxidation could be
the use of a thermal oxidation system,
this may result in high running costs
because natural gas would have to be
brought into the factory area.
A thermal oxidation approach in certain
cases can prove inflexible, because if
demand dropped the abatement plant
would still need to be kept running. A

that provides an expected availability of
more than 99% and can be equipped
with a superior performance catalyst to
reduce environmental emission limits.
AirProtekt’s engineering solutions are
tailored to address specific local emission
requirements but are also specified to
comply with national and international
regulations as well as detailed global
company-specific guidelines or
operational procedures.
Trevor Lawton, AirProtekt’s managing
director said: “Our engineering team
often specifies an electrically pre-heated
abatement system to provide processors
with a very low maintenance solution.
We also aim to offer systems that
operate quietly to ensure that residential
properties are not disturbed.”
The industrial air pollution control
catalysts favoured by AirProtekt
comprise thin-walled honeycomb
supports coated with a fine dispersion
of Platinum Group Metals, impregnated
into a high surface area washcoat.
The catalysts, which form the heart of
AirProtekt’s catalytic oxidation system,
are derived from proven autocatalyst
technology and offer benefits that
include a long effective life, and the
ability to withstand high temperatures.
A range of high poison resistance catalyst
types are available from AirProtekt,
which include a standard VOC oxidation
catalyst; a chlorinated VOC catalyst;
an LHC catalyst for methane, ethane,
propane as well as a sulphur-resistant
catalyst. AirProtekt’s systems are also
capable of running at low catalyst
operating temperatures to minimise
running costs and thermal stress.

GRP pipes and fittings
GRP pipes from ECE Pipe Systems are produced between DN 300mm and
DN 2,800mm, and SN 2500-10,000N/m2 . The GRP pipes, which are produced
with a continuous filament winding process, are widely used in drinking water,
sewerage, irrigation networks, hydro-power projects, industrial waste projects
and geothermal-cooling water projects.
ECE also produces metal reinforced HDPE corrugated pipes and fittings. The
MRP pipes produced are between DN 600mm and DN 1,600mm. MRP pipes
that are reinforced using steel plates have stiffness classes between SN 4 and
SN 20kN/m2. The pipes are used in sewerage-storm water networks, septic
discharge projects, gutters, cable manhole-highway culvert applications and
drainage systems.
ECE Group has 25 years’ experience in the production of concrete and
reinforced concrete pipes, and has two established factories in Manisa and
Adapazarı in Turkey.
