Likewise, it has proven that closedloop operation is both possible and feasible. Many PureSOx customers have chosen hybrid systems with closed-loop modes, while others have chosen hybridready 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. Closed loop with open possibilities PureBallast 3 meets tough challenges with ease Alfa Laval PureBallast 3, the third generation of the leading ballast water treatment technology, now has minimized holding time in United States waters – and is ready for revised G8 requirements in 2020. Today PureBallast 3 owners can deballast as needed, in all water salinities and anywhere in the world. An updated type approval from the U.S. Coast Guard (USCG) minimizes USCG holding time to just 2.5 hours, which is only needed when crossing between Captain of the Port Zones. In addition, PureBallast 3 is prepared for the revised G8 requirements that soon must be met by any system prior to installation. Though the stricter guidelines take effect in October 2020, Alfa Laval is one of just a handful of suppliers with revised G8 certificates in hand. Regulations are not the only challenge, however. The PureBallast 3 offering continues to develop, providing simpler and smarter answers to complex needs. Last year saw the launch of a 1500 m3/h reactor, which enables even more compact systems for large flows. And today there are also vessel-specific solutions, such as deckhouses and booster pump units for tankers. More steam without burning more fuel Why let valuable energy go up in smoke? The Alfa Laval Aalborg Micro is an extremely compact new waste heat recovery boiler that maximizes the energy efficiency of auxiliary engines. Tomorrow’s blended fuels will need to be properly stored at a higher ambient temperature – Alfa Laval’s recommendation is 10–15°C above the pour point. That means steam needs may actually increase after 2020, even if the fuels are pumped at lower temperatures than today. That extra steam is easy to acquire with the Alfa Laval Aalborg Micro waste heat recovery boiler. A unique coil design makes it just as effective as standard smoke-tube boilers. But with its remarkably lower height and smaller diameter, the Aalborg Micro is exceptionally easy to retrofit.
