PROREACT BIOREACTORS FOR GAS FERMENTATIONS
Customized plants to carry out fermentations with reactive gases under EX conditions. Customized, efficient and safe.
REQUIREMENTS FOR GAS FERMENTATION PLANTS
The research and application of gas fermentations for the production of platform chemicals and bio-based energy sources is attracting increasing attention.
The technologies for the use of energy-rich gases such as synthesis gas or steel mill exhaust gases allow for a lower environmental impact and resource conservation compared to fossil fuels.
Gas fermentations are often so special with regard to the apparatus and process engineering requirements that conventional bioreactors quickly reach their limits or may not be operated at all due to safety aspects.
The special properties of gas fermentations are for example:
- Low solubility of reaction gases such as H2, CO or CH4
- Low growth rates of biomass
- Explosion hazard
- Contamination of the raw gases
- Exhaust emissions / requirements for exhaust gas treatment
- Robust, cost-effective processes with low energy consumption required
This results in certain design requirements, which are fully met by PROREACT ATEX bioreactors depending on the bioreactor equipment selected:
- Consideration of the applicable ATEX requirements
- Use of special gassing systems
- Design as high pressure fermenter
- Devices for cell retention
- Inerting before process start
- Special gas routing
- Cleaning of the raw gas
- Exhaust gas cleaning
Expertise in handling explosive processes
FRINGS has decades of expertise in explosion-hazardous bioprocesses and provides solutions for laboratory and pilot plant scale with its PROREACT ATEX series.
We recommend the use of high-performance gas flushing systems to improve gas input rates, especially for large-scale industrial plants. Our FRINGS TRG aeration turbines are particularly suitable for this purpose.
Comparable requirements for explosion protection are also met by plants for processes in which reactive gases are produced during biocatalysis. The PROREACT ATEX series reactors have also been used successfully in this field.
