Biogas is often a mixture of gasses produced by enzymatic biological processes. Unlike natural gas it contains components produced by the fermentation of organic material like methane (CH4), carbon dioxide (CO2), ammonia (NH3) and smaller amounts of hydrogen sulphide (H2S). During combustion H2S and other organic compounds, in particular chlorines and fluorines, blends to form strong acids. Biogas is widely used as a fuel gas for heating unregulated boilers. The contamination can causes severe damage to the equipment
The biogasfilters of Parker Twin Filter capture and retain over 90% of the contaminants; this increases the equipment lifetime and the productivity and decreases the operational running and maintenance costs.
Next to the fuel gas application, Biogas can be conditioned to “Green Gas”, which can be blended into main stream natural gas. Therefore the biogas has to meet very high standards.
The separation of liquid particles is performed by coalescers. The particle arresting is done by HEPA filter cartridges.
