Alfa Laval PureSOx water cleaning process now patented


Company says the patented technology is vital to secure compliance in either hybrid or closed loop mode.



Sweden's Alfa Laval - a leader in heat transfer, centrifugal separation and fluid handling - reports that its process for cleaning scrubber water with high-speed centrifugal separator technology as part of the PureSOx exhaust gas cleaning system has now been patented. The company's statement has been included below.

Alfa Laval PureSOx is a front-runner among marine sulphur oxide (SOx) scrubber systems, which allow the continued use of HFO while meeting the emission limits for operation in ECAs. Now with the enforcement in Emission Control Areas (ECAs) in place, the ability to deliver compliant systems is even higher. The technology in the Alfa Laval PureSOx H2O water cleaning unit allows this.

The PureSOx H2O water cleaning unit is a specialized example of an Alfa Laval core technology: the high-speed centrifugal separator. Developed over the course of several years, it removes the soot from the circulation water in closed-loop mode. The unit is completely unaffected by pitch and roll, which sets it apart from other cleaning systems on the market. It has a footprint of just 6 m2 and a modular construction based on three flexibly placed skids.

A process for cleaning scrubber water with high-speed centrifugal separator technology as part of Alfa Laval's PureSOx exhaust gas cleaning system has now been patented. The patented technology is of the utmost importance to secure compliance in either hybrid or closed loop mode. Especially examples in Belgium and Germany where ports don't allow open loop scrubbers, require a system with this specialized technology.
