SULOFF Technical information (PDF 2,8 MB)

Removal of sulfane (H2S) from biogas; technology developed in cooperation with the Institute of Chemical Technology Prague. The cleaning is carried out in an adsorption apparatus with a fixed bed through which biogas is flowing. The cylindrical stand of the adsorption apparatus is made of corrosion-proof steel with an opening in the upper part for filling sorbent. For the purpose of gas inlet, the adsorption apparatus is equipped with the inlet pipeline with a standardised connecting flange. The adsorption apparatus is situated on the concrete base, bearing blocks are anchored. On its outer side, the adsorption apparatus is insulated with mineral and glass wool with a thickness of 100 mm - in the aluminium jacket covering the whole adsorption apparatus.

Sorbent: The adsorption is performed using impregnated activated carbon in the form of small-sized granules. The weight of the charge is according to the type of the adsorption apparatus.
Field of application: The line of desulphurisation units serves for the removal of sulfane by means of adsorption using a special adsorption material - activated carbon with the subsequent catalytic oxidation to elemental sulphur that will be trapped by sorbent. The adsorption material deactivates in consequence of the release of elemental sulphur. Therefore, it is necessary to replace it after a certain period of time. The desulphurisation efficiency amounts to 96 - 99%.
Servicing: The servicing provided by KS Klima-Service a.s. ensures the contactless change of the adsorption apparatus.
