Optimisation of biogas production by infrared spectroscopy-based process control / Dieter Wolf in Journal of natural gas science and engineering, Vol. 3 N° 5 (Octobre 2011)  

Public ISBD [article]  inJournal of natural gas science and engineering > Vol. 3 N° 5 (Octobre 2011) . - pp. 625–632 Titre : Optimisation of biogas production by infrared spectroscopy-based process control Type de document : texte imprimé Auteurs : Dieter Wolf, Auteur ; Harald Von Canstein, Auteur ; Cathrin Schröder, Auteur Année de publication : 2012 Article en page(s) : pp. 625–632 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Biogas Biomethane Near infrared spectroscopy (NIRS) Process automation Raw biogas Ultrasonic volumetric flow metre Résumé : Biomethane being a storable and base load capable energy carrier has an important role in the energy policy of the German government. The high targets for future production levels require an efficient production of biogas to yield the most biogas from either energy crops or organic waste, and to fully utilise the gas production capacity of biogas plants. Both processes can yet be optimised, and the two novel measuring technologies presented here may play an important part in this. The continuous analysis of biomass as input for a biogas plant and of the media inside the digesters was conducted by near infrared-based spectroscopy. First results indicate a high degree of accuracy for key process parameters compared to laboratory analyses. The measurement of the volumetric flow of raw biogas in the different stages of the process was performed with ultrasonic biogas meters. First results show a high degree of precision. The results will be used to develop a model towards process automation.
