Goal Copyright Longer timeframe - Current state of technology as benchmark - BUT MAIN GOAL: Develop NEW process flow diagrammes (PFDs), two main reasons
4
Current processes (bioprocesses and conventional): State-of-the-art Future bioprocesses Horizon value for productivity Concentration glucose Scale PFDs - Principle considerations (1/2)
5
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)
