Real time control of biogas reactors
During three long monitoring campaigns the following primary techniques were evaluated and used for online monitoring aiming at process control. Micro gas chromatography was able to monitor gas composition quantitatively in a fast and reliable way. Membrane-inlet mass spectrometry did the same, but demanded periodic cleaning and maintenance. Near-infrared spectroscopy combined with thermometricsgave an indication of the VFA level in the manure and showed that a complex media in real life differ a lot from model systems where scientific work has shown more promising results. An interface was also developed in order ot work with the large dataset. (Energy 11)
