Plant and method for the abatement of undesired polluting components contained in biogas to be treated

-19. (canceled)

Method for the abatement of polluting components contained in biogas, comprising:

• providing, in a plant for the treatment of biogas, a plurality of filtering tanks suitable to be connected to a supply line of biogas to be treated and each containing adsorbing means for the adsorption of said polluting components when streams of biogas flow through each filtering tank;
• during the operation of the plant, switching said plurality of filtering tanks cyclically among them so that, at least a first filtering tank of said plurality of filtering tanks is temporarily isolated from the supply line of biogas;
• subjecting the at least a first filtering tank once isolated to a regeneration phase of the adsorbing means contained therein and saturated by polluting components previously adsorbed, while maintaining one or more of the remaining filtering tanks of said plurality of filtering tanks connected with the supply line with the respective adsorbing means which continue to adsorb the polluting components contained in the streams of biogas flowing through them.
