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.
