Development of instrumentation systems as a base for control of digestion process stability in full-scale agricultural and industrial biogas plants

摘要

This article deals with the analysis of instrumentation from three modern German full-scalenbiogas plants with different inputs and typical process engineering concepts for Germannconditions. The measured results from each plant and the suitability of the instrumentationnused are evaluated and assessed. Conclusions are also made about improving the use andnarchitecture of the instrumentation. The analysis results show which benefits and optimumncombination of on-line and off-line instrumentation could result for the control andnautomation of industrial and agricultural biogas plants.
