Process control in biogas plants

Abstract

Efficient monitoring and control of anaerobic digestion (AD) processes are necessary in order to enhance biogas plant performance. The aim of monitoring and controlling the biological processes is to stabilise and optimise the production of biogas. The principles of process analytical technology (PAT) have been identified as some of the most promising on-line facilities for monitoring and controlling heterogeneous bioconversion processes. The future trend is to keep procedures as simple as possible, but to have available on-line monitoring systems with early warning strategies for plant operators, which would help to avoid significant process disturbances. The general aim is to move the processes efficiently towards their theoretical maximum. Mathematical modelling of AD is another method to help control the process and avoid significant instabilities during fermentation. Such models can improve the understanding of biological processes.
