Exhaust gas cleaning
IMO established tough marine SOx regulations aimed at reducing air pollution related to fuel sulphur content, including a 2020 global sulphur cap. Fortunately, you can meet IMO SOx limits without switching to more expensive low-sulphur fuel, by installing Alfa Laval PureSOx. Alfa Laval is the leader in marine scrubbers for wet exhaust gas cleaning, which ensures compliance while using HFO. Alfa Laval PureSOx has been at sea since 2009, and every system is in compliance today.
Alfa Laval PureSOx continues to lead the way
- Years of operating experience at sea
- Removal of more than 98% of exhaust gas SOx
- Up to 80% reduction of particulate matter (PM)
- Proven performance – every system installed is operating and in compliance
- Many returning customers

Why choose an Alfa Laval PureSOx scrubber system?
One good reason is achieving compliance with the 2020 global sulphur cap, or the stricter SOx limits in Emission Control Areas (ECAs). Another is the return on investment, which can be a short as one year. PureSOx is also regarded as the leading SOx scrubber solution, with proven performance.

PureSOx celebrates 10 years at sea
Only one year is left until the global sulphur cap becomes reality. But there’s every reason to feel confident. As of 2019, Alfa Laval PureSOx has been at sea for a decade – complying in both open- and closed-loop operation.
SOx legislation – global and ECA
MARPOL Annex VI establishes regulations for the prevention of air pollution from ships and includes a global fuel sulphur cap, as well as stricter regulation in Emission Control Areas (ECAs). The legislation refers to fuel sulphur levels, but compliance can also be achieved by cleaning SOx from the exhaust gas.
Tighter SOx limits
MARPOL Annex VI progressively reduces the allowed sulphur content of marine fuels. As of January 2020 there is a global cap of 0.5%S, while a 0.1%S limit exists in ECAs.
The aim is to keep harmful sulphur oxides (SO2 and SO3) and particulate matter (PM) from being released into the air. The IMO allows higher sulphur fuels to be used with SOx scrubbers, which achieve the same result by cleaning the exhaust gas.

SOx compliance options
Today's HFO has a sulphur content well above the limits established by MARPOL Annex VI. Realistically, shipowners have three options, each with different implications.
Three ways to comply
Install a SOx scrubber
+ Allows continued use of economical HFO
- Payback time depends on fuel price delta (HFO vs low-sulphur)
Use low-sulphur fuel
+ Low investment cost
- Higher long-term costs than using HFO with a scrubber
- Uncertain fuel price and availability
Switch to LNG
+ Always in SOx compliance
- High investment cost
- Complicated retrofitting
- Limited infrastructure and uncertain fuel price
Return on scrubber investment
Investing in a scrubber system like PureSOx provides a cost advantage over shipowners who choose low-sulphur fuels to comply with MARPOL Annex VI. The difference in fuel price determines payback time and, subsequently, profit.
The PureSOx difference
SOx scrubbers provide an opportunity for long lasting fuel cost savings. No scrubber system lets you make more of that opportunity than PureSOx from Alfa Laval.
Satisfied customers in SOx compliance
Alfa Laval PureSOx has been at sea since 2009, providing reliable compliance with SOx emission limits. Over 250 PureSOx systems have been installed to date, and every one of them is in compliant operation today. Among the satisfied PureSOx customers are many who have returned to Alfa Laval for additional PureSOx systems.
Customer case – PureSOx and life on board
Dutch ship owner Spliethoff was among the first to install PureSOx. The company currently has 18 PureSOx systems, plus considerable insight when it comes to working with them. “The reliability has been very high,” says Technical Support Engineer Roland Hoogeveen.
