Why is Desulfurization Important?

Sulfur Oxides (SOx) emitted by ships pose a severe threat to human health and the environment. To minimize ships' environmental impact, the International Maritime Organization (IMO) significantly reduced the global limits on the sulfur dioxide in the fuel oils. This new regulation went into effect January 2020, reducing the maximum sulfur content outside special "Emission Control Areas" to 0.5%. The maximum sulfur content in designated "Emission Control Areas" such as the North Sea and the Baltic Sea is already at 0.1%. Ships navigating through these areas must either use fuels that meet the regulated sulfur limit or install desulfurization systems.

The new regulation presents many challenges to the ship owners because it leaves them with only 3 options. They can either use low sulfur fuel, switch to alternate fuel such as LNG, or install desulfurization systems such as exhaust cleaning technologies. Low sulfur fuel is significantly expensive compared to high sulfur fuel. The initial investment for alternative fuels is also extremely high, leaving desulfurization technologies as the only viable and cost-effective option.

The Value of Desulfurization Technology

Stakeholders from ship owners and cargo owners to policy makers and everyone in between need to transition to using low sulfur fuels or installing desulfurization systems in a short amount of time. With the cost of low sulfur fuels being extremely high, the key to meeting these new regulations is installing desulfurization technologies.

These cost-effective and compliant technologies
enable stakeholders to:

  • Minimize the amount of sulphurous fuel gases into the
  • Improve human health and environmental safety.
  • Meet IMO’s global sulfur emissions regulations.
  • Avoid problems caused by unpredictable low sulfur fuel
