CamPure 32 is the new ideal Camfil molecular filtration media for the removal of hydrogen sulfide during the production of biogas in an anaerobic process.
The methanization unit was commissioned in 2012 for an investment of 900,000 €. The unit is composed of a digester, a post-digester, a storage pit for the feedstock, and a pit containing the liquid digestate. Biomass feedstock is composed of solid and liquid manure for 70% complemented by 30 % of plant (wheat, corn, and catch crop).
The biogas is converted into heat and electricity (cogeneration) by a 250 kW Scania dual-fuel engine. The generated heat is used on the farm and the electricity is sold and fed into the local power grid. The methanization unit produces around 150 m3/h of biogas, which is contaminated with significant amounts of hydrogen sulfide (H2S). To protect the engine from corrosion, it is necessary to remove the H2S from the biogas. Engine corrosion leads to unscheduled maintenance, operational downtime, and loss of process efficiency.
To remove the H2S, Camfil offers CamPure 32, a specific molecular filtration media with a high H2S adsorption capacity.
The media is available in the form of a 500 kg big bag or in the form of a 28 L carton.
“CamPure 32 has the advantage of having an attractive price compared to other activated carbon in the market while having an excellent H2S adsorption rate. The lifetime of the product should be longer, which will allow us to delay the media replacement.
We could also notice that the quantity of dust during the can loading/unloading was low.”
