Mixing the Future of Renewable Energy

In the fast-evolving world of renewable energy, biofuels are transforming how we power transportation, industry, and the planet. From biodiesel and bioethanol to biogas and next-generation algal oils, one constant remains: precise, efficient mixing defines performance and profitability.

PerMix engineers advanced mixing systems that optimise reaction kinetics, ensure uniform dispersion, and stabilise temperature and phase behaviour—giving biofuel manufacturers higher yields, lower costs, and cleaner results.


The Critical Role of Mixing in Biofuel Production

Every litre of biofuel begins with a complex chemical or biological transformation. Feedstocks must be blended, catalysts dispersed, and multi-phase reactions precisely controlled. Poor mixing leads to unreacted oil, phase separation, energy waste, and off-spec fuel.

PerMix systems are designed to eliminate those risks. Our mixers enhance mass transfer, maintain homogeneity, and deliver the process consistency modern biofuel production demands.


Mixing Challenges in Biofuel Manufacturing

Biofuels production involves diverse feedstocks and complex reactions. Each introduces unique challenges:

  • Multiphase systems: Oil, alcohol, catalysts, and biomass often coexist—uniform mixing ensures complete conversion.
  • Variable viscosity: As reactions progress, the mixture thickens or thins dramatically.
  • Temperature control: Exothermic reactions can create hotspots, reducing efficiency or degrading product quality.
  • Gas evolution: In fermentation or digestion, gas bubbles must be released without disrupting mixing.
  • Abrasive residues: Biomass particles and catalysts wear down conventional equipment.
  • Cross-contamination risk: Switching feedstocks requires clean-in-place capability and sanitary design.

PerMix mixers are built to master these extremes—keeping production stable, efficient, and scalable.


Key Stages Where Mixing Drives Performance

1. Feedstock Preparation & Pretreatment

Homogenising oils, fats, or biomass with catalysts, methanol, and co-solvents ensures full contact before reaction begins.

2. Reaction & Conversion

Controlled shear and temperature maintain even catalyst distribution and maximise reaction yield during transesterification or enzymatic conversion.

3. Separation & Washing

Gentle agitation allows clean phase separation while avoiding stable emulsions.

4. Neutralisation & Polishing

Precise blending of water, acids, or surfactants removes residues and neutralises catalysts.

5. Final Blending

Homogeneous mixing of additives and stabilisers delivers fuel that meets specification every time.
