ADI Systems has considerable experience offering complete biogas handling, treatment, and utilization systems for the recovery of renewable energy as part of its anaerobic treatment systems. The biogas generated as a by-product of the anaerobic digestion process consists of mainly methane and carbon dioxide. It is a valuable product for the ...
Bio or sewage gas is saturated with water vapour. Condensation can occur within the pipework systems of digester systems as a result of fluctuating temperatures. The ennox condensate pot allows for the collection and controlled discharge of any condensation water accumulations.
The gas removed from biogas digestion or fermentation units can be heavily contaminated with foam particles, various particulate matter and water vapour. A pre-filtration of the gas (often adequate enough) can be achieved with the use of an ennox gravel filter.
Gas from bio or sewage processing systems are often contaminated with water vapour or very sparsely distributed small particulate matter, which, when used for example in CHP units can cause operating problems or either damage. For the fine cleaning of the gases before utilization an ennox ceramic fine filter is used.
Biogas, sewage gas and landfill gas contains not only water vapour but also a whole host of additional impurities such as hydrogen sulphide, NH3 and siloxane, which, when processed in the utilization system can not only lead to a reduction in efficiency, but also result in damage of the system.
Biogas can contain large quantities of poisonous hydrogen sulphide depending upon the fermentation process and which input materials are used. This gas can cause permanent damage to gas engines or other consumers of the biogas.
Condensation from saturated biogas collects at the lowest points in the pipework, in bends etc. This can negatively influence the effective operation of biogas systems.
Fine sediment and foam particles in the saturated biogas originating directly from the digestion can make it´s way into the pipework system. In order to eliminate sediment accumulation in the pipework an ennox sediment trap can be used.
HydroThane STP® BSP stands for Biological deSulphurization Process and is a simple biological process that removes hydrogen sulphide H2S from the biogas without the use of chemicals.The biogas is fed into vertical column(s) with a packing media in counter current flow, the BSP process can be seen as a combination of a conventional chemical ...
HydroThane STP CSP stands for Chemical Scrubbing Process. In principle, the removal of H2S is based on the transfer of gaseous hydrogen sulphide to the water phase: H2S (g)H2S (l) followed by the reaction of dissolved hydrogen sulphide with hydroxide (caustic): H2S (l) + OH-HS- + H2O HS- + OH-S2- + H2O HydroThane STP CSP has the following ...
