Interim results Generic Approach Interim results

Goal Copyright Longer timeframe - Current state of technology as benchmark - BUT MAIN GOAL: Develop NEW process flow diagrammes (PFDs), two main reasons

Current processes (bioprocesses and conventional): State-of-the-art Future bioprocesses  Horizon value for productivity  Concentration glucose  Scale PFDs - Principle considerations (1/2)

Future separation processes  Only continuous fermentation processes  Plant size: Assume TODAY  FUTURE  Wherever possible, avoidance of energy intensive processes (e.g., distillation and evaporation); on the other hand relatively high fuel requirements may be acceptable in view of the use of renewable energy from biowaste streams.  Membrane processes are generally preferred due to their (expected) low energy use and the avoidance of high salt loads.  The avoidance of salt loads also makes electrodialysis an attractive option for the future. The high power requirements are considered acceptable in view of on-site electricity production from biowaste streams.  Extraction should be avoided, wherever possible. Alternatively, benign solvents should be used. Properties of compounds and process design determine energy use.  Adsorption may be somewhat less attractive due to common use of solvents for regeneration. PFDs - Principle considerations (2/2)
