As well as being the established choice of scrubber for Emission Control Areas (ECAs), Alfa Laval PureSOx is proving its capabilities on the Great Lakes. The system will soon be installed on a cement carrier that will operate in the region as part of the NovaAlgoma fleet.
NovaAlgoma Cement Carriers Limited has recently expanded its fleet with the M/v Nacc Quebec. This ecologically efficient self-discharging bulker will be converted from an existing vessel in China and will begin her operation in 2017. Connected to its Wärtsila four-stroke 6L38B main engine will be an Alfa Laval PureSOx exhaust gas cleaning system, configured with a U-design scrubber in a hybrid arrangement.
Scrubbers are a means of profitable compliance with sulfur legislation on the Great Lakes. Closed-loop scrubbing is necessary, however, due to the strict wash water discharge requirements of the US Vessel General Permit (VGP). PureSOx offers well-proven water cleaning technology based on centrifugal separation, which will allow the M/v Nacc Quebec to sail continuously in closed-loop mode. Nevertheless, a hybrid system was selected for full operational flexibility, giving it the additional ability to sail in open-loop mode when allowed.
Following careful consideration of both U-design and I-design PureSOx scrubbers, a U-design was also chosen for this particular installation. The U-design offered the best fit for the space on board, as well as the possibility of operating in bypass mode.
In selecting PureSOx for the M/v Nacc Quebec, prior experience with Alfa Laval and Alfa Laval equipment played an important role. “We trust in the Alfa Laval brand and wanted to have the Alfa Laval PureSOx system in our fleet,” says Mr Francesco Costagliola, Technical Director.
