PureSOx

Why choose an Alfa Laval PureSOx scrubber system?

There are many good reasons for choosing a scrubber to comply with the 2020 global sulphur cap, or the even stricter SOx limits in Emission Control Areas (ECAs). Added to these are the many good reasons for choosing PureSOx, the leading SOx scrubber solution and the secure choice for peace of mind.

SOx legislation – global and ECA

To combat air emissions, MARPOL Annex VI establishes a global fuel sulphur cap, as well as stricter regulation in Emission Control Areas (ECAs). The legislation refers to fuel sulphur levels, but compliance is also possible by cleaning SOx from the exhaust gas.

Tightening SOx limits

MARPOL Annex VI progressively reduces the allowed sulphur content of marine fuels. As of January 1st, 2020 there is a global cap of 0.5%S, while a 0.1%S limit applies in ECAs.

The aim is to keep harmful sulphur oxides (SO2 and SO3) and particulate matter (PM) from being released into the air. This is why 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. That leaves you as a ship owner with three options, each of which has different implications.

Three ways to comply

Install a SOx scrubber

Pros:
+ Allows continued use of economical HFO

Cons:
- Payback time depends on fuel price delta (HFO vs low-sulphur)

Use low-sulphur fuel

Pros:
+ Low investment cost

Cons:
- Higher long-term costs than using HFO with a scrubber
- Uncertain fuel price and availability

Switch to LNG

Pros:
+ Always in SOx compliance

Cons:
- High investment cost
- Complicated retrofitting
- Limited infrastructure and uncertain fuel price

Why scrubbers? The Grimaldi Group explains

 

Don't just take our word for it. The Grimaldi Group has been installing Exhaust Gas Cleaning systems to comply with regulations regarding SOx emissions since 2014.

In this film, Mr. Dario Bocchetti and Mr. Alberto Portolano from the Grimaldi Group explain why their company has chosen the scrubber technology and why they place their trust in Alfa Laval.
