Abstract

System and method for performing a regenerative desulfurization of raw biogas. Raw biogas comprising hydrogen sulfide is injected in a container containing a material adapted for capturing and converting into solid sulfur the hydrogen sulfide. Biogas without hydrogen sulfide is extracted from the container, the hydrogen sulfide being captured and converted into the solid sulfur by the material. The injection of the raw biogas comprising the hydrogen sulfide in the container is then stopped. A regeneration gas heated at a predetermined temperature is injected in the container, the temperature allowing extraction of the sulfur from the material in the form of sulfur compound(s). The regeneration gas and the sulfur compound(s) are extracted from the container. The injection of the regeneration gas in the container is then stopped. A control device controls the execution of the regenerative desulfurization, using collected data representative of operating conditions of the system.
