Disturbing Substances In Biogas

Disturbing Substances In Biogas

Biogas (also referred to as digester gas) is a gas mixture emerging from the fermentation of organic substances. One of the main constituents in biogas is hydrogen sulphide, which, however, is a disturbing element and therefore needs to be broken down.

Your issue

corrosion in digesters (such as bioreactors)
possible odour nuisance (e.g. from gas holders, hydrolysis, pre-tanks, substrate reservoirs)
adverse effects in the system (e.g. in catalysts, piping components)
adverse effects on utilities (such as lubricants)

Consequences

higher operating costs (e.g. shorter oil change intervals) to the point of a plant breakdown (e.g. due to motor failure)
reduced turnover and feed-in tariff due to biogas plant failure
loss of subsidies (bonuses for low formaldehyde and other emissions)
unstable fermentation
increased environmental pollution (SOx emissions)

Our solution for you

Design and construction of external bio-chemical biogas desulphurisation plants (UGN®-BEKOM system) or external bio-chemical exhaust air purification systems for biogas plants (UGN® hybrid filter system) based on bio-chemical and functionalized cellulose filtering materials.

Our work is based upon

biogas measurements (CH4, CO2, O2, NH3, H2, H2S) prior to designing a biogas desulphurisation plant
analysis of the biogas forming processs
measurements of the exhaust air emerging from pre-tanks, hydrolysis tanks, slurry storages (CH4, CO2, O2, H2, H2S, NH3, VOC, mercaptans)
customized design and dimensioning of biogas desulphurisation plants and exhaust air purification systems
In addition, we provide
implementation planning
issuing of explosion prevention documents
construction surveillance, on-site assembly
