초록

바이오가스화는 유기성폐기물을 처리하는 과정에서 발생되는 메탄가스를 포함하는 환경 친화적인 연료를 생산하는 기술이다. 바이오가스화는 유기성폐기물의 해양투기 금지 이후 안정적인 육상처리일 뿐만 아니라 신재생에너지원으로 인정받으면서 세계적인 관심을 받고 있다. 최근에는 생산된 바이오가스를 고품질화하여 도시가스 및 수송용으로 이용하는 추세가 증가하고 있다. 바이오가스화 현장시설에서는 아직도 잦은 고장으로 바이오가스 생산이 저하되고, 또한 생산된 바이오가스를 효과적으로 정제하여 이용하는 것이 미흡한 실정이다. 이 연구에서는 바이오가스 생산 및 이용 시설에서의 문제점들을 파악하고, 최적으로 바이오가스를 도시가스 및 수송용으로 활용 가능하기 위한 가이드라인 및 기술지침을 마련하고자 하였다.

Biogasification is a technology that uses organic wastes to reproduce as environmental fuels containing methane gas. Biogasification has attracted worldwide attention because it can produce renewable-energy and stable land treatment with prohibit from landfilling and ocean dumping of organic waste. Biomethane is produced by refining biogas. It is injected into natural gas pipeline or used transportation fuel such as cars and buses. 90 bio-gasification facilities are operating in 2016, and methane gas production is very low due to it is limited to organic wastes such as food waste, animal manure, and sewage sludge. There are seven domestic biomethane manufacturing facilities, and the use of high value-added such as transport fuels and city-gas through upgrading biogas should be expanded. On the other hand, the rapid biogasification of organic wastes in domestic resulted in frequent breakdowns of facilities and low efficiency problems. Therefore, the problem is improving as technical guidance, design and operational technical guidance is developed and field experience is accumulated. However, while improvements in biogas production are being made, there is a problem with low utilization. In this study, the problems of biomethane manufacturing facilities were identified in order to optimize the production and utilization of biogas from organic waste resources. Also, in order to present the design and operation guideline of the gas pretreatment and the upgrading process, we will investigate precision monitoring, energy balance and economic analysis and solutions for on-site problems by facility.
