With experience from over a decade of work with SOx scrubbers and exhaust gas cleaning, Alfa Laval has put together informative resources to help in your decision process.
“Staying ahead in SOx compliance” takes a deep look at emissions compliance legislation and the reasons for choosing a SOx scrubber. In addition, it explores the choices on the market and the key considerations when selecting a scrubber supplier. With illustrations, diagrams and tables, it provides both a clear overview and important insights. To order a printed copy or download the PDF, fill out the form below.
The documents and studies below offer more information, not only about PureSOx specifically, but also about SOx scrubbers in general and the issues involved in making a selection
Alfa Laval provides complete documentation specific to shipyard needs. The shipyard documentation is divided into: - Advice for the specific vessel - PureSOx Design Guide for engineering, P&IDs and equipment drawings - PureSOx Installation Manual To obtain shipyard documentation or more information, please contact Alfa Laval.
An Alfa Laval PureSOx scrubber system can be configured in three different operating arrangements: open-loop, closed-loop or a combination of these two, hybrid.
A closed-loop scrubber can use either seawater, or fresh water with an alkaline additive. The water is recirculated and as it becomes dirty, the circulation water is cleaned, discharged, and replenished to retain scrubber capacity. The scrubber can be used anywhere and at any time, but its operating costs are higher than the open-loop configuration.
In an open-loop scrubber, seawater is used to scrub the exhaust gas. Once the water has passed through PureSOx, it is discharged back into the sea, in compliance with IMO regulations. This configuration has the lowest investment and operating costs, but its use may be limited by low water alkalinity or local water discharge regulations.

Alfa Laval is at the forefront of marine scrubber technology, thanks to hundreds of successful installations over the past decade. PureSOx is continuously being developed, both at the Alfa Laval Test & Training Centre and on board.
PureSOx applies Alfa Laval’s core technologies of fluid handling, heat transfer and separation. Centrifugal separators are especially important for a closed-loop or hybrid scrubber system, where it is needed to ensure compliant cleaning of the circulation water.
Much of the ongoing development of Alfa Laval PureSOx occurs at the Alfa Laval Test & Training Centre, a unique research facility located in Aalborg, Demark. The centre is a full-size machine room on land, with complete process lines integrated around a 2 MW marine diesel engine.
The PureSOx scrubber installed here can be pushed to its limits under controlled conditions, which accelerates both the speed and quality of testing. Learn more about our Test & Training Centre here
