CompAir solutions for Al-Nasr
Full Field Development Project
Gardner Denver’s CompAir brand has
supplied a complete compressed air system
to Hyundai Heavy Industries (HHI), as
part of its engineering, procurement and
construction (EPC) contract with the Abu
Dhabi Marine Operating Company for the
Nasr Full Field Development Project.
Located 130 km northwest of Abu Dhabi
in the Al-Nasr oil field, the new ‘super
complex’ from HHI will aim to help increase
the daily oil production capacity of the
offshore field from 22,000 to 65,000 barrels.
The facility includes a gas treatment
platform, which is where the compressed air
system from Gardner Denver will be sited.
Gardner Denver’s scope of supply included
design, fabrication, supply, inspection,
transportation, testing and commissioning
of the compressed air equipment and plant
systems.
The compressed air system includes
four oil-free, air-cooled rotary screw
compressors, two sets of heatless,
desiccant-type air dryers, two DCS/ESD unit
control panels and UCP (BN3500) machine
monitoring systems, filters and accessories.
The mechanical packages were installed
outdoors on the top deck of the facility, and
so these needed to be able to withstand the
elements, while the control and monitoring
unites were located indoors.
The compressors use air-cooled
technology to cool and seal the compression
process, maximising the units’ overall
efficiency, while sealed-for-life bearings
that require no oil lubrication are also
used on the machines. The compressors’
compact and noise-limiting enclosure helps
simplify the installation process, as well as
ensuring quiet compressor operation at all
times.
All the piping within the compressor and
dryer packages from CompAir are 316L
grade stainless steel, to help protect against
the elements. The lubrication system,
including the oil reservoir, also uses 316L
grade stainless steel to comply with the
project’s specification.
Miele works
with McDonald’s
Supported by Miele,
McDonald’s is tackling
fatbergs by adapting its
washing machines.
The modified Miele ‘Little
Giant’ washing machines are
now standard across almost all
1,300 McDonald’s Restaurants
in the UK, used to launder all
mopheads and cleaning cloths
on site. Using the grease
recovered from these wash
cycles, McDonald’s Restaurants
has also been able to increase
its biofuel production.
McDonald’s Restaurants
has been installing specialist
grease recovery units (GRUs)
for several years. However, a
typical 85°C grease removal
wash cycle would deposit
grease and fat into a GRU at
high temperatures, reducing
its ability to separate and
be extracted. So, Miele also
developed a bespoke and
redesigned wash cycle using
lower temperatures to allow
the grease to be recovered
more efficiently, without
compromising on hygiene.
This allows the grease
to be collected more
easily, extracted and used
towards the production
of vehicle biofuel. Miele
worked with McDonald’s to
adapt the machine to their
requirements; replacing the
hoses, valves and door seal
with silicon-based items to
make them more durable and
hard-wearing.
