Elimination of Methane Slip and Odor Emissions From Biogas Production Plants

Catator has in a recently completed study, SGC report no. 287, 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 a relatively limited source strength (concentration) of odor substances. Depending on extremely low odor threshold (<1 ppb), this still can cause symptoms within a large radius of the release site. This means, in addition to health and safety problems for people working on the plants, also inconvenience for local residents. 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).

Bioptech joins Cleantech Inn Sweden

Phosphorus is essential to life on earth – plants, humans and animals need phosphorus to grow. However, it is a finite resource and causes eutrophication when spread in water streams. Bioptech offers an active filter to collect this finite resource from wastewater and recycle it as fertiliser, closing the phosphorus cycle and reducing eutrophication. Our […]
