Hydrogen sulphide - Import export

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. The majority of the hydrogen sulphide gas can be effectively removed by using an ennox active carbon filter ACF. In addition, the active carbon filter can be used for the removal of damaging siloxane from the biogas, furthermore for the neutralization of unpleasant odours in outgoing air and tanks.

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 to the system. The dehumidification of the gas before processing is a basic preliminary requirement in order to permit an efficient usage of the biogas and an investment in the sustainability of the utilization system. With the ennox gas chill dryer the gas to be processed is passed through a heat exchanger where the cooled gas can expel any moisture which drips and is collected as condensate. According to the technical requirements of the installation a post-warming or an economical and ecological energy recovery system can be implemented into the system.
