Topic

The project focuses on the development of a competitive metrological solution for online data capture of important process data to be used as control variables for process control in biogas plants designed for the processing of biogenic residues and organic waste.

Aims

The project aims to apply measurement solutions, based upon newly developed sensor technology for the online measurement of key process data. The goal was to increase the degree of automation in biogas plants and to propose new approaches for process optimization. Additionally, it was envisioned to include other materials into the digestion process as a result of the process optimization.

Measures

  • Measurement in practically relevant biogas plants which operate using a two-stage biogas process (consisting of a hydrolysis and a methane stage) for treating biogenic residues and waste
  • Extension / Modification of an existing biogas pilot scale plant
  • Examination of measurement systems in the GICON biogas pilot scale plant
  • Validation and comparison of methods for the determination of key components for assessing the stability of a two-stage fermentation process as well as field trials in two-stage biogas plants

Focus

GICON

Exploration of the complex microbiological processes occurring in biogas plants and their optimization through the development of highly sensitive measuring systems, for a long-term stable direct use in the various liquid and solid phases present in multistage biogas plants. This can be carried out in the form of spatially distributed sensor arrays for the measurement of pH, ORP, dissolved gases and volatile fatty acids.

KSI

  • Development and adaptation of systems for measuring dissolved components in biogas media 
  • Development and construction of operating and measuring circuits
  • Validation and comparison of methods for the determination of key components for assessing the stability of a two-stage fermentation process as well as field trials in two-stage biogas plants
