Abstract (en)
[origin: WO2017093701A1] The device (20) for decarbonating biogas comprises: - a first tank (205), for holding a volume of liquid comprising lime and water, comprising: - a first part (275) comprising: - an inlet (215) for biogas into the liquid, - an inlet (210) for the liquid and - a partition (280) for overflowing of the liquid to a second part (285), - the second part comprising: - a means (265) for collecting calcium carbonate and - an outlet (220) for the liquid, configured to release a part of the liquid when the volume of the liquid in the first tank is greater than a predefined maximum retention volume, - a second tank (225), for holding a volume of liquid comprising lime and water, comprising: - an inlet (230) for water released by the first tank, - an outlet (235) for decarbonated biogas and - an outlet (240) for the liquid, - a pipe (245) for recirculating the liquid leaving the second tank to the first tank, - a means (246) of recirculating the liquid leaving the second tank to the first tank, - a sensor (250) for sensing the pH of the liquid and - a means (255) of supplying lime to the liquid when the pH of the liquid is less than a predefined setpoint value.
