Fuel emulsions for shipping and industry
- The RAPTECH CaviFlow® inline modules work with targeted hydrodynamic cavitation to produce stable emulsions from components that are difficult to mix, such as heavy fuel oil, biodiesel and optionally water. The result is a finely dispersed and homogenized fuel mixture that is characterized by high stability and efficiency.
This high-performance homogenization and dispersion process facilitates the production and homogenization of alternative fuel mixtures - including renewable energy sources - for emission-reduced and consumption-optimized combustion. The fuel emulsions produced with CaviFlow® are particularly suitable for applications in shipping as well as in stationary industrial and power plants, using environmentally friendly fuels and sustainable fuels. Cavitation technology contributes to energy efficiency through alternative fuels and offers a promising solution for the energy sources of the future.
RAPTECH cavitation technology is suitable for:
- Emulsions with heavy fuel oil (HFO)
- Combinations of HSFO, VLFO and ULSFO
- Biodiesel as a renewable energy source
- Bioethanol for industrial use
- Pyrolysis oil from recycled plastics (WPPO)
- Hydrogenated vegetable oil (HVO)
- Glycerine-based fuel solutions
- Water-in-fuel emulsion systems
- Qualitative upgrading of heavy fuels
- Cavitation-based fuel reforming
- Optimization of atomization properties
- Demand-oriented use of additives
