Sensor based analysis

Optimization of the utilization of biomass by combined processing to biogas and resources by fermentation and to synthesis gas by gasifying of the hardly transformable biological residuals is the aim of this research project. Both processes are highly complex and continuous registration of the key-parameters by sensors is needed to enable optimization of efficiency by advanced process control methods. For this purpose, at Institute for Sensor and Information Systems, Karlsruhe University of Applied Sciences (i) an in-situ sensor system is developed for continuous analysis of the most important acids formed in the fermentation process and (ii) a new sensor system is built up for continuous analysis of the tar content in the synthesis gases produced by the gasifier.
