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 sulphur 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.
