| Zusammenfassung: | The present invention relates to a biogas upgrading system which comprises: a pretreatment apparatus treating sulfur dioxide from biogas; an absorption membrane contactor receiving an absorbent from an absorbent tank and carrying out a reaction between the biogas introduced from the pretreatment apparatus to discharge the carbon dioxide-absorbed absorbent and also discharge pure methane to a methane storage tank; and a desorption membrane contactor receiving the carbon dioxide-absorbed absorbent from the absorption membrane contactor and separating carbon dioxide from the absorbent to discharge carbon dioxide to a carbon dioxide storage tank and also discharge the absorbent, from which carbon dioxide is separated, to the absorbent tank.
본 발명은 바이오가스로부터 이산화황을 처리하는 전처리장치; 흡수제탱크로부터 흡수제를 공급받아 상기 전처리장치로부터 유입된 바이오가스와 반응시켜 이산화탄소가 흡수된 흡수제를 배출하고 순수한 메탄을 메탄저장조로 배출하는 흡수용 막접촉기; 상기 흡수용막접촉기로부터 이산화탄소가 흡수된 흡수제를 공급받아 흡수제로부터 이산화탄소를 분리하여 이산화탄소 저장조로 배출하고 이산화탄소가 분리된 흡수제를 상기 흡수제탱크로 배출하는 탈거용 막접촉기;를 포함하는 것을 특징으로 하는 바이오가스 고질화 시스템에 관한 것이다. |
