Abstract

Details of biogas quality are in a decisive role when determining the biogas utilization and the purification requirements and equipments. Comprehensive measurements of the biogas composition together with knowledge of the actuating factors could offer a potential tool for on-line process control and troubleshooting. In the present work, the effects of process changes related to reactor loading variations on concentrations of selected trace compounds in biogas were studied. The results showed that the process was well under control up to the load of 8 kgVS/m3d. Gaseous concentrations of siloxanes, hydrogen sulfide as well as most VOCs remained quite constant. However, the formation of gaseous ethanol was found to accelerate at the load-increasing points. Furthermore, a significant temporary increase in N2O formation was occasionally found due to some oxygen penetration in the reactor.
