Fuel emulsions for shipping and industry
- RAPTECH UADA technology uses 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 fuel mixture that is characterized by high stability and efficiency.
This high-performance homogenization process with adjustable mixing ratio enables the use of alternative fuels - including renewable energy sources - for emission-reduced and consumption-optimized combustion. The fuel emulsions produced in this way are particularly suitable for applications in shipping and in stationary industrial plants for energy generation, using environmentally friendly fuels and sustainable fuels. These technologies contribute to energy efficiency through alternative fuels and offer a promising solution for the energy sources of the future.
UADA cavitation technology is suitable for:
- Stable emulsions HFO
- Stable emulsions HSFO | VLFO | ULSFO etc.
- Biodiesel
- Bioethanol
- Pyrolysis oil from plastic waste
- Hydrogenated vegetable oil HVO
- Glycerine
- Water-in-fuel emulsions
- Upgrading heavy fuels
