Biobutanol, bioacetone & emerging fuels

Apply fermentation and separation engineering to biobutanol, bioacetone and higher-alcohol projects. For bio-aviation-fuel development, we evaluate upstream alcohol production and purification interfaces with the selected conversion licensor. Fuel conversion, pathway certification and finished aviation-fuel qualification are separate project requirements.

Connect the feedstock to the conversion route

Corn, cassava and wheat routes require preparation suited to starch conversion. Molasses and sugar-based feeds require a different front end. Feedstock composition, seasonal variation and handling conditions inform the process design; they also affect the solids and impurities presented to the downstream plant.

Coordinate fermentation and distillation

The design aligns fermentation throughput and discharge conditions with the distillation feed requirement. Operating and laboratory information connects raw-material quality, conversion and fermentation performance to final product quality. Training covers the process route, equipment functions, routine observations and the records needed to investigate a deviation.
