<p>Invention relates to a method and device for removal of hydrogen sulphide from biogas. A method is characterised in that the biogas is introduced to the device through a pipe and it flows out in its upper part and then flows around convex, non-permeable cover and is forced into a chamber in the shape of funnel with porous plates where there is an absorbing solution and while passing through the absorbing solution and porous plates, insoluble copper sulphide is formed, which following crystalisation settles on the funnel-shaped bottom of the chamber, while biogas devoid of hydrogen sulphide is collected from the device through outlet port. A device is characterised in that it consists of a chamber (8), which in its lower part forms a conical funnel (9) which ends with the outlet port (6) for discharge of sediment while in upper part of funnel (9) inside the chamber (8) there is a convex, non-permeable cover (2) with horizontal plates (4) and in the central part of chamber (8) from down there is a pipe (1) introducing the biogas to the chamber where there is an absorbing solution (3) and in the upper part of chamber (8) there is an outlet port (5) and in its side part there is an inlet port (7).</p> |
