Abstract

Korea is natural gas importer which imports a lot quantities which 20% of the volume of US exports in 2018. Biogas which can satisfy gas demand and respond effectively to climate change, will be an alternative. However, only 20% of biogas production is sold, which is also not efficient and difficult to use. The purpose of this study develops an optimal purification system for supplying biogas as city gas. We develope an optimal system by analyzing biogas for system selection, finding cases for system design, developing scenario, and developing a cost - benefit tool.

우리나라는 천연가스 수입국으로 2018년 미국이 수출한 물량의 20%를 수입할 정도로 많은 양을 수입하고 있다. 이에 가스 수요를 만족시키며, 기후변화 대응에 효과적으로 대응할 수 있는 바이오가스는 대체제가 될 수 있을 것으로 생각된다. 그러나 바이오가스의 생산량의 20%만이 판매되고 있고, 이 역시 효율이 좋지 못해 활용하기 어려운 실정이다. 본 연구에서는 바이오가스를 도시가스로 공급 할 수 있는 최적의 정제 시스템을 개발을 목적으로 하였다. 시스템 선정을 위한 바이오가스에 대한 분석, 시스템 설계를 위한 사례 발굴, 시나리오 구성, 비용편익 툴을 개발하고 사례 적용하여 최적의 시스템을 개발하고자 하였다.
