The present invention relates to a biomethane refining apparatus comprising an adsorption unit which includes: an adsorption portion filled with an adsorbent for adsorbing sulfur compounds; and a separation membrane located at a rear end of the adsorption portion on the basis of the flow of a gas to be treated and installed on an outer wall of the adsorption unit to separate carbon dioxide. The biomethane refining apparatus according to the present invention is advantageous in that the apparatus can refine biomethane with high efficiency even with a small size. 본 발명은 황화합물을 흡착하는 흡착제가 충진된 흡착부; 및 처리대상 기체의 흐름을 기준으로 상기 흡착부의 후단에 위치하며, 흡착 유닛의 외벽에 설치되어 이산화탄소가 분리되는 분리막;이 구비된 흡착 유닛을 포함하는 바이오메탄 정제장치에 관한 것으로, 본 발명에 의한 바이오메탄 정제장치는 작은 크기로도 높은 효율로 바이오메탄을 정제할 수 있는 장점이 있다.
