Efficient emulsion technology for marine fuels in maritime and industrial applications
- RAPTECH UADA technology uses targeted hydrodynamic cavitation to create stable emulsions from difficult-to-mix components such as heavy fuel oil, biodiesel and optionally water. This finely dispersed marine fuel mixture is characterized by high stability and efficiency and provides an excellent basis for emission-reduced combustion.
Thanks to this powerful dispersion and homogenization process, which enables an adaptable mixing ratio, marine fuels - including renewable energy sources - can be used optimally to reduce fuel consumption and lower emissions. The marine fuel emulsions produced are particularly suitable for maritime use and in stationary industrial plants for energy generation.
UADA cavitation technology is ideal 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
- 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

Technological and innovative advantages of RAPTECH marine fuels
Lower emissions with full ISO 8217 compliance with marine fuels
Optimized combustion of marine fuels through finely dispersed emulsions
RAPTECH's advanced UADA cavitation technology enables highly efficient homogenization of marine fuels - especially with demanding components such as heavy fuel oil or biogenic fuel components. By creating ultra-fine emulsions, the droplet size of marine fuels is significantly reduced, resulting in improved combustion and a higher energy yield.
Thanks to the fine microstructure, emissions can be noticeably reduced when using marine fuels. This technology is fully compliant with the requirements of ISO 8217:2024 and is ideal for the use of modern, sustainably formulated marine fuels. RAPTECH thus creates the basis for a future-proof and low-emission energy supply - both in the maritime and stationary industrial sectors.

RAPTECH completely dispenses with chemical additives such as surfactants, emulsifiers or polymers during production. The emulsions are based on purely physical processes - for a clean, efficient and environmentally friendly solution in the field of marine fuels.
- Component blending:
In the first step, the marine fuels are composed of different base materials in a precisely defined ratio. The formulation is flexible and is individually adapted to the respective area of application.
- Emulsification:
The prepared mixture passes through the emulsification process using UADA cavitation technology. The different phases of the marine fuels are intensively and stably combined with each other.
- Homogenization:
In the RAPTECH ultrasonic acoustic flow reactor (UADA), the marine fuel emulsion is finely homogenized. This results in an even distribution of the components, which ensures particularly clean and efficient combustion behavior.
- Quality assurance:
Finally, every marine fuel is tested for its physical and chemical stability. All emulsions meet the applicable requirements of ISO 8217:2024 and are approved for permanent use in a maritime or industrial environment.
