Alfa Laval PureSOx scrubber systems – 10 years at sea
The arrival of 2019 leaves just one year until the global sulphur cap becomes reality. But as the marine industry scrambles to ready itself, an important milestone has already been reached. The new year marks a decade since the first vessel set sail with an Alfa Laval PureSOx scrubber on board.
In 2009, the RoRo vessel DFDS Ficaria Seaways entered dry dock for an expansion of its cargo space. While the vessel was being rebuilt, a hybrid PureSOx system – able to perform closed-loop as well as open-loop scrubbing – was retrofitted to clean the exhaust gas from its 21 MW main engine. At the time of the pilot installation, the prospects for SOx scrubbers were anything but certain.
“Ten years ago, there were many who didn’t think SOx scrubbers were feasible,” says Erik Haveman, Sales Director, Exhaust Gas Cleaning at Alfa Laval. “People simply weren’t convinced that a scrubber could meet ECA limits while operating in a marine environment, and the doubts about closed-loop scrubbing were even greater. Alfa Laval had sold scrubbers as part of inert gas systems for many years, and we had the water cleaning expertise needed for closed-loop operation. But the system and the challenges here were on a completely new scale.”
A decade later, the merits of both the scrubber and the centrifugal water cleaning unit are undeniable. The PureSOx system on Ficaria Seaways has spent thousands of hours in compliant operation – and is still going strong. In fact, so is every other PureSOx system ever installed. This flawless track record is unmatched by any other supplier to the industry, and it is underpinned by Alfa Laval’s 100 years of marine experience as a whole.
