초록
가스 하이드레이트는 고압과 저온 조건에서 객체분자(guest molecule)인 저 분자량의 가스와 주체분자(host molecule)인 물 분자가 결합하여 고체상으로 형성된 화합물을 일컫는다. 물과 가스에 의해서 형성이 된다는 점, 포집 가스의 종류에 따라 다양한 결정구조가 형성되며 선택적으로 가스를 포획할 수 있는 장점으로 인하여 이를 지구온난화 가스 저감을 위한 산업공정에 활용하는 연구가 최근 활발히 진행되고 있다. 본 논문에서는 CO2 또는 CO2-N2 하이드레이트에 관한 전반적인 최근 연구 동향을 파악하여 이를 실제 산업 현장에 적용하는 경우에 대한 기술적 가능성을 모색해 본다. 특히 대규모 CO2가 배출되면서도 이에 해당하는 연구가 활발히 진행되지 않았던 제철 공정에 대한 적용성을 중점적으로 검토하였다.
Gas hydrates are crystalline solids composed of water and gas molecules. Water molecules are linked through hydrogen bonding and create cavities(host lattice) that can capture a large variety of guest molecules under appropriate conditions, generally high pressure and low temperature. Recently, many researchers try to apply gas hydrates to industrial processes to capture greenhouse gases due to the facts that the process is eco-friendly and target gas molecules can be preferentially captured. In this paper, we introduced recent studies on CO2 and CO2-N2 mixture hydrates to evaluate the feasibility of industrial application of gas hydrate technology to CO2 capture process. Specifically, we put emphasis on the technical feasibility of CO2 separation in steel industry using gas hydrate formation principles.
