Field tests – odor abatement tests

Catator has in a recently completed study demonstrated the potential by catalytic methods to effectively reduce emissions of greenhouse gases and odorous compounds. The study was performed in connection to different biogas production plants and other processes related to biological systems such as composting and anaerobic digestion as well as wastewater processing. The results show that all organic emissions (including odor) can be reduced with high efficiency.

The study shows that the emissions often involve limited source strength (concentration) of odor substances. Depending on extremely low odor threshold.

Both demonstration units (MRO-500 and DEO-100) have been evaluated in collaboration with different partners in the project and for an extended period of time (>1000 hr) at two different test sites. The performance was followed by total VOC analysis (FID equipment) and by odor tests on collected gasbags with an odor panel.

Results from odor intensity test on sex different test sites with a DEO-100 unit. The test is performed by an odor panel (> 10 persons) as a “blind-test” on three different unmarked gas-bags containing untreated gas (IN), treated gas (OUT) and reference gas (REF, office air).

The results from the study are presented in a Swedish Gas Center report (SGC report no. 287). SGC is a leading edge company within the field of sustainable development having a national Swedish assignment. The report can be down loaded from SGCs web page
