In 10 years at sea, Alfa Laval PureSOx has shown that SOx limits can be met while operating on more economical high-sulphur fuel. Likewise, it has proven that closed loop operation is both possible and feasible. Many PureSOx customers have chosen hybrid systems with closed-loop modes, while others have chosen hybrid ready systems, which simplify later upgrading from an open-loop to a hybrid system.

Now PureSOx has grown even more flexible when it comes to closed loop, thanks to a new modular and upgradeable PureSOx water cleaning system (WCS). It combines high-speed separation – an Alfa Laval core technology which is the most effective means of water cleaning – with flocculator and membrane options, plus the ability to handle both Mg(OH)2 and NaOH as alkali, and to choose between seawater or fresh water. In short, it provides the most cost-effective solution for both present and future needs.
