Advantages of the CaviFlow® cavitation modules
Hydrodynamic Cavitation
Advancing Biodiesel Processing and Fuel Quality
Improving biodiesel production refers to advanced process innovations - such as RAPTECH cavitation technology - that improve efficiency, economics, feedstock flexibility, and fuel stability and performance. While biodiesel is widely seen as a renewable alternative to fossil diesel, traditional production processes often face challenges such as long reaction times, high chemical consumption, limited feedstock options and post-processing inefficiencies.
Cavitation is a physical phenomenon in which microscopically small vapor bubbles form and collapse within a liquid. This creates local hotspots, intense shear forces and extreme micromixing.
CaviFlow® cavitation technology uses controlled hydrodynamic cavitation to optimize all key stages of biodiesel production - without additional chemicals or complex mechanical systems. This approach represents a significant advance in biodiesel improvement, transforming batch-based, resource-intensive processes into faster, cleaner and scalable continuous operations.

Cleaner feedstocks and lower operation costs
Pretreatment Improvement: Degumming & Conditioning
Vegetable oils and animal fats used for biodiesel production usually contain gums, waxes and phosphorus compounds. These impurities impair the fuel quality and shorten the service life of the catalytic converter. The cavitation generated by the CaviFlow® inline module improves pretreatment by:
As a result, cavitation-assisted degumming provides cleaner raw materials, lower chemical consumption and lower operating costs and thus makes an important contribution to improving biodiesel in the pre-treatment phase.
- Breaking up the rubber structures through extreme shear forces
- Release of bound phosphorus compounds
- Improvement of the oil-water mass transfer without excessive chemical additives
As a result, cavitation-assisted degumming provides cleaner raw materials, lower chemical consumption and lower operating costs and thus makes an important contribution to improving biodiesel in the pre-treatment phase.
Economical and flexible use
Esterification of High-FFA Feedstocks
Low-cost and sustainable feedstocks such as waste fats and animal fats often contain high levels of free fatty acids (FFAs), which require costly and time-consuming pre-treatment. The cavitation processes of the CaviFlow® inline module significantly accelerate esterification in biodiesel production by:
This enables the economic use of previously less valuable or problematic raw materials and increases flexibility in the selection of raw materials. It also supports large-scale processes for converting waste into fuel - a key aspect of modern biodiesel production.
- intensifying the contact between alcohol and FFAs
- increasing the reaction kinetics in localized high energy zones
- reduce the FFA content within minutes instead of hours
This enables the economic use of previously less valuable or problematic raw materials and increases flexibility in the selection of raw materials. It also supports large-scale processes for converting waste into fuel - a key aspect of modern biodiesel production.
Simplified scaling and reduced capital
Improving transesterification: The main reaction
Transesterification converts triglycerides into fatty acid methyl ester (FAME) and glycerol - the core step in biodiesel production. Compared to conventional stirred tank reactors, cavitation-based systems such as CaviFlow® offer the following advantages:
This results in a smaller plant footprint, simplified scaling and reduced capital and operating expenses, making cavitation a fundamental technology for improving industrial biodiesel production.
- Reduction of reaction time from hours to minutes
- Reduced methanol and catalyst consumption
- Compact reactor designs with continuous flow
- Improved yield and process consistency
This results in a smaller plant footprint, simplified scaling and reduced capital and operating expenses, making cavitation a fundamental technology for improving industrial biodiesel production.
Faster and higher qualified
Separation & Purification Efficiency
The downstream separation of biodiesel and glycerine is often slowed down by emulsion formation and soap formation. Cavitation by the CaviFlow® inline module improves purification by:
The result is faster phase separation, lower water and energy consumption and higher final fuel purity, which contributes directly to a cost-effective improvement in biodiesel production.
- Minimization of side reactions
- Reduction of soap formation
- Weakening of the emulsion stability
The result is faster phase separation, lower water and energy consumption and higher final fuel purity, which contributes directly to a cost-effective improvement in biodiesel production.
Improved oxidation stability and combustion
Storage Stability & Fuel Performance
Even after production, biodiesel can suffer from phase instability, component separation and uneven combustion during storage. Cavitation in the CaviFlow® inline module provides a purely physical post-treatment solution that:
Studies show that cavitation-treated biodiesel has smoother combustion and improved oxidation stability, extending fuel life and engine performance.
- Biodiesel rehomogenized at the nanoscale
- Improves blending stability and atomization
- Unburned hydrocarbons and particulate emissions reduced
