Urea

Urea

MHService has a stock of Urea in Måløy and Ålesund – and can deliver nationwide within a short time.

Urea is used as part of SCR technology (Selective Catalytic Reduction) to reduce nitrogen oxide (NOx) emissions from ship engines. This is a vital measure to comply with strict emission regulations set by international maritime organizations, such as IMO Tier III standards. The benefits of using urea for ships include:

1. Reduced NOx Emissions

Urea converts harmful NOx emissions into harmless nitrogen and water through a chemical reaction in the SCR catalyst.
This helps improve air quality and meet international environmental standards.

2. Regulatory Compliance

Urea solutions are essential for operating in Emission Control Areas (ECA), where strict NOx limits apply.
Ensures compliance with IMO Tier III requirements for new ships.

3. Environmental Friendliness

The reduction of NOx contributes to minimizing environmental impact and slows the formation of acid rain and smog.

4. Improved Operational Efficiency

SCR systems using urea can be tailored to optimize engine performance, potentially reducing fuel consumption compared to alternative solutions.

5. Lower Long-Term Operating Costs

Although SCR technology requires an initial investment, it offers a cost-effective solution over time due to reduced fines and less need for high-quality fuels to meet emission requirements.

6. Flexibility in Fuel Choices

Urea solutions can be used with various fuel types, including heavy fuel oil (HFO), marine diesel oil (MGO/DMA), and low-sulfur fuel.

7. Proven Technology

SCR with urea is a well-established and reliable technology, already widely used in land-based applications such as power plants and vehicles.

Practical Considerations

  • Urea is readily available as a water-based solution (commonly called AUS 40 for marine use).
  • Easy storage and transportation make it practical for maritime applications.

By using urea as part of SCR systems, shipping companies can reduce environmental impact, ensure regulatory compliance, and maintain efficient operations.
