| description | The present invention relates to a method for purifying biogas using an adsorption-membrane combined process, comprising the following steps: supplying biogas to a gas compressor; adsorbing carbon dioxide from the compressed biogas through an adsorption device; and separating and purifying desorption gas in the adsorption step through a separation membrane module, recycling purified methane with the biogas and separating and discharging carbon dioxide. The method contributes to upgrading biogas by improving the recovery rate of methane to over 95%.
본 발명은, I) 바이오가스를 가스 압축기로 공급하는 단계; II) 상기 압축된 바이오가스로부터 흡착장치를 통하여 이산화탄소를 흡착하는 단계; 및 III) 상기 흡착단계에서의 탈착가스를 분리막 모듈을 통하여 분리 정제함으로써, 정제된 메탄은 바이오가스와 함께 재순환시키고 이산화탄소는 분리 및 배출하는 단계;를 포함하는 흡착-분리막 복합공정을 이용한 바이오가스 정제방법에 관한 것으로, 메탄의 회수율을 95% 이상으로 크게 향상시킴으로써 바이오가스의 고질화에 기여할 수 있다. |
