PureSOx
Alfa Laval PureSOx is a leading marine scrubber solution for compliance with SOx regulations. Effective in open-loop or closed-loop scrubbing, it can also be delivered as a hybrid scrubber system with both open-loop and closed-loop scrubber modes. Since 2009, PureSOx scrubbers have been installed on hundreds of marine vessels. Their owners enjoy reliable SOx compliance and high fuel economy – plus the peace of mind ensured by Alfa Laval’s marine scrubber services.
Don’t just comply with SOx regulations – be a step ahead
- Removal of more than 98% of exhaust gas SOx through exhaust gas cleaning
- Nearly 15 years at sea – hundreds of marine scrubbers in proven SOx compliance
- Open-loop, closed-loop or hybrid scrubber configurations
- Leading water treatment to support closed-loop scrubber operation
- Easy global access to scrubber spare parts, scrubber training, scrubber maintenance services and more
When it comes to complying with marine SOx regulations, Alfa Laval PureSOx has long been leading the way. PureSOx was the first marine scrubber system installed for SOx compliance, and hundreds of PureSOx scrubbers have followed. From the very beginning, our PureSOx offering has included hybrid scrubber technology – matching the economy of an open-loop scrubber with the future-proof security of a closed-loop scrubber.
Besides having lower fuel costs, PureSOx owners benefit from Alfa Laval’s long experience, high production quality and deep scrubber knowledge. The last, which includes our expertise in scrubber water treatment, is the foundation for a comprehensive range of marine scrubber services.
Technology
PureSOx scrubber configuration
Alfa Laval PureSOx can be configured in three different operating arrangements – all of which can handle multiple exhaust gas sources. The most popular choice is a hybrid scrubber, which balances economy with operating flexibility.
PureSOx open-loop
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.
PureSOx hybrid
A hybrid scrubber combines both open-loop and closed-loop modes. Open-loop mode reduces operating costs whenever possible, but you can easily switch to closed-loop mode if you need to comply with local water discharge regulations.
PureSOx closed-loop
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.
Alfa Laval PureSOx scrubber technology
PureSOx is based on proven Alfa Laval core technologies and over 50 years of specific experience with marine scrubbers. We can configure a PureSOx system to match your sailing profile as well as the physical constraints of your vessel – two reasons why PureSOx is the scrubber of choice and why every installation is operating and in compliance today.
Simplify compliance with PureSOx Connect
The user-friendly, graph-based reporting of PureSOx Connect simplifies proof of compliance. Operators can easily review data on board and create reports for authorities. The capabilities of PureSOx Connect go far beyond reporting, however, when you connect the system to the internet. The PureSOx Connect services include three modules: reporting & compliance, performance & benchmarking and service. Together, they will help you to make service predictable and plannable.
Installing
Installing an Alfa Laval PureSOx scrubber system
Alfa Laval's unique insights and project management experience – developed through hundreds of PureSOx projects and more than 250 installations – are assurance for a successful SOx scrubber installation.
Project management – installation
Installing a SOx scrubber system is a major undertaking. You want to minimize downtime and you may have to deal with inflexible shipyard slots. PureSOx Project Manager, Mark Aarbodem, explains how Alfa Laval safeguards the process.
Strong cooperation and smart planning
"Alfa Laval has worked with engineering companies and shipyards in many PureSOx projects. Few suppliers can match our experience, whether in number of scrubber installations or variety of vessel types and installation challenges we've had to deal with.
"Each new project begins with a kick-off phase, where the customer and our dedicated project team meet to align the goals and the way forward. Our project team includes engineers from all disciplines, which ensures engineering work of the highest quality. A dedicated Project Manager, who is a single point of contact for everything concerning the order, coordinates the team. The Project Manager makes sure the design, installation, commissioning and service go as smoothly as possible.
"Over the years, we've developed well-documented procedures to facilitate installation and class approval. PureSOx is delivered as prefabricated components and modules and every aspect of the installation is planned well in advance. We can save time by doing preparation while the vessel is operating, and the final commissioning can also be handled en route.
"In most cases, through strong cooperation and planning, your vessel's total downtime can be limited to 2–4 weeks."
