Latest generation of scrubber launched

The company says that the previous version of PureSOx has been operating at sea since 2009 and is claimed to be among the most prominent scrubbers on today’s market, with 50 systems ordered for 45 vessels.

PureSOx 2.0 is more compact, and is claimed to offer greater flexibility, which Alfa Laval says suits a wider range of vessels. Claimed benefits include new placement possibilities and lower installation costs, as well as the option of powder dosing in closed-loop mode.

The diameter of the absorber, which forms the bulk of the scrubber body, has been reduced by around 15%, while the control system occupies half the space of its predecessor. Modular construction has allowed the unit to be distributed across three skids, for easier installation and greater flexibility in design. The new unit can handle boiler exhaust as well as engine exhaust, making it possible for a single scrubber to supply the needs of main engines, auxiliaries and boilers.

The scrubber itself attenuates noise in PureSOx 2.0, meaning it can be positioned before the silencer, rather than after as previously required, reducing back pressure and the lower mounting improving stability.

“PureSOx 2.0 retains the well-documented PureSOx strengths,” said René Diks, Alfa Laval manager marketing and sales for exhaust gas cleaning. “What it adds are new advances that reinforce the system’s position at the leading edge of marine scrubber technology. Every PureSOx system ever installed is in use and operating within ECA limits.”
