Turbo screw compressors for smelting
plant
Compair has sold twenty of its turbo screw compressors to Bechtel and HRV for the building of an aluminium smelting plant.
Compressed air specialist CompAir has proved its cool credentials in Iceland thanks to the hot performance of both its industrial and portable compressors In total 20 compressors including its world-beating turbo screw range were purchased as part of an exclusive partnership with global engineering solutions provider Bechtel and Icelandic engineering specialist HRV, for the construction of one of the world's largest aluminium smelting plants in Iceland

A hat-trick of benefits in data recording

Tasked with providing a complete process solution for the construction of the one billion dollar plus Alcoa Fjarandeth Smelter Project, owned by Alcoa, the world's leading producer of aluminium, Bechtel approached CompAir to provide the compressed air solutions required for both the construction and operating phases of the project.
Located 6 km east of Reyandeth, within the municipality of Fjarandeth; in East Iceland, where temperatures reach a chilling -2 degrees, the low - emission aluminium facility has taken more than three years to construct and is on schedule to be completed in December 2007.
Expected to produce up to 346,000 metric tons of aluminium per year, the productivity of the facility will depend heavily on the reliability of the process and the machinery used to power it.

A carpet manufacturer in Durham is saving time and money by installing ABB ACS 600 drives on its carpet looms.
Using 150,000 cubic meters of concrete and 26,000 tons of steel, the development of the project will span more than 2 km, consisting of 336 'pots' operating at 365 Amp DC.
Each 'pot' will produce approximately 2 metric tonnes of aluminium every day.
On completion the additional supporting facilities will include a reduction line over 1 km long, a carbon facility, cast house and a port facility provided by the municipality of Fjarandeth.
Tasked with such a large-scale development, Bechtel required a whole range of compressors to perform numerous construction tasks, including concrete vibration for storage tank wall forming and power for general machine tool operation This included portable C50s, C73s with electrical generators, C150-14 high-pressure units and two revolutionary fuel-saving C180TS-9 turbo screw models.
Bechtel also installed a stationary L30 compressor to run the cathode rodding induction furnace, a key process housed within the development.
Commenting on the project and the purchase of CompAir equipment, CompAir regional sales manager Franz Weisbrod said: "Having worked with Bechtel on a number of challenging and unique projects across the world, we have a real understanding of the support and service it has come to expect from CompAir.
By offering a complete solution for its compressed air needs, we have been able to form an exclusive partnership involving our distributor MEST to provide the equipment, service and support Bechtel needs to get the job done.
"Working to tight deadlines in difficult terrain with up to 1,600 workers on site at any one time, Bechtel not only had to consider the programme time constraints of the three year construction programme, but also the environmental impact work would have on the unique landscape.
"As with any project of this scale, reducing the environmental impact of construction and operation is extremely important and a key reason why Bechtel chose to purchase two of our industry-leading turbo screw C180TS-9 compressors.
Located outside in harsh weather conditions, the C180TS-9 came into its own when used to power no fewer than 40 concrete vibrators to form a cylindrical concrete bauxite container in just 10 days.
Not only did the C180TS-9 help to reduce the construction time, thanks to its world-beating fuel economy, Bechtel was able to reduce the operating impact on the environment by up to 30%, saving more than 10 litres of fuel per hour of operation, without any difference in performance." Energy use and performance were also a major focus with electricity needed to operate the aluminium plant supplied by a nearby hydropower station, reducing the need to burn fossil fuels, whilst benefiting from the natural resources Iceland has to offer.
