Located on the site of the former Aalborg Shipyard in Aalborg, Denmark, the new Alfa Laval Test & Training Centre is an imposing structure. The massive ship simulation facility has a testing area of 250 m2, where pride of place is given to a new generation of PureSOX, currently under development. Added to this is a dedicated control room and a training complex for visitors.
To as great an extent as possible, the Alfa Laval Test & Training Centre is designed to mimic the operation of a commercial vessel. For this reason the equipment is not installed as isolated components, but rather as an integrated system complete with heat exchangers and other auxiliaries.
The new AlfaLaval Test&Training Centre acts as a one-to-one ship arrangement
At the heart of the testing area layout, and also connected to the control platform, is a large medium-speed marine diesel engine. This four-stroke, 9L28/32 engine from MAN supplies approximately 1.9 MW of output power via an AvK generator, which will be fed into the local grid of the city of Aalborg.
The fuel for the engine, which will be HFO and / or MDO for the time being, will be treated using a standard setup of Alfa Laval fuel line products. In the case of HFO the also installed inline scrubber can be tested, as well as the latest version of Alfa Laval’s Ballast Water Treatment System.
Besides pursuing further developments related to the PureSOX scrubber technology, the facility will be targeting NOX reduction. Having worked extensively with exhaust gas recirculation (EGR) via the PureNOX scrubber water treatment system, the company will begin a parallel exploration of selective catalytic reduction (SCR) in a project with official funding from the Danish Environmental Protection Agency. To this end, the exhaust line has been fitted with an SCR unit, developed in cooperation with Haldor Topsøe.
For the purposes of testing, there is also an exhaust gas heater, which will ensure the high exhaust gas temperatures necessary for SCR when the engine is not at full load.
