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 that already exist 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. From January 2020 there will be a global cap of 0.5%S, while a 0.1%S limit already exists in today’s 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
  • Use low-sulphur fuel
  • Switch to LNG

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

Return on scrubber investment

Investing in a scrubber system like PureSOx provides a cost advantage over ship owners who choose low-sulphur fuels to comply with MARPOL Annex VI. The difference in fuel price determines your time to payback and profit.
