Bioalcohol production: Biochemical conversion of lignocellulosic biomass p. 315-339. (2010)

Online monitoring of bioethanol production is challenging due to the complex, viscous sample matrix, also containing solids. Suitable targets for online measurement are identified and potential monitoring techniques in addition to standard physicochemical measurements are reviewed. Advantages and limitations of chromatographic techniques, spectroscopic methods and software sensors are discussed in detail. In conclusion, bioethanol production processes should certainly benefit from online measurement of key process variables, especially if measurements are incorporated in process control loops. However, convincing case studies are lacking, and therefore development of suitable sampling methods and online measurement techniques should first be prioritized.
