Expertise and applications for gas/liquid reactions
 

For many years, FRINGS has been providing gas/liquid reaction technology to the chemical, biotechnology and food processing industries.
We offer our application engineering, reactors and customized equipment based upon practical experience.

Rotor-stator aerators for process technology

The core component of our high performance mass transfer reactors is the FRINGS rotor-stator aerator FRIBORATOR.
It provides:

  • Fine-bubble aeration (gas/liquid interphase boundary)
  • Free jet mixing

The gas transfer from fine primary bubbles through the gas/liquid interphase boundary into the solution determines the absorption and reaction speed, providing that the reaction is independent from the dissolved gas concentration.

The ingredients of the solution to be aerated, especially salts, alcohols and organic acids, determine the coalescence of the bubbles, the decrease in the number of bubbles and the effective mass transfer area.

The mixing of liquid volumes with the free jets produced by the aeration turbines is due to the displacement and the expansion of the rising gas bubbles.
This expansion can also be used for the flotation of ingredients in the solution.

FRINGS is committed to the constant development of advanced technology to achieve high gas transfer rates and a maximum yield at optimum mixing, with low energy and maintenance.


Applications

FRINGS reactor systems are used in a wide variety of applications and processes:
