Gas Hydrates: A Cleaner Source of Energy and Opportunity for Innovative Technologies (Review)
Peter Englezos,Ju Dong Lee 한국화학공학회 2005 Korean Journal of Chemical Engineering Vol.22 No.5
The global energy system is characterized by a gradual de-carbonization and move to cleaner burning tech-is desired. Gas hydrate found in the earth’s crust is considered a source of natural gas that is essentially 100% methane(CH4) gas. Natural gas hydrate estimates worldwide range from 10,000 to 40,000 trillion cubic meters (TCM). Effortsare underway to exploit this resource. These methane hydrates in the earth’s crust also have the potential to be a signif-icant factor in global climate change. Moreover, gas hydrates ofer opportunities for the development of innovativetechnologies (separation of CO2 from CO2/N2 and CO2/H2 mixtures, CO2storage and H2 storage). In this work we assess the progress towards exploitation of gas hydrates as a resource for meth-ane (cleaner energy) and sumarize the state of the art with respect to the role of gas hydrates in the development of innovative technologies.
가스 하이드레이트 형성을 이용한 CO₂ 분리 및 회수 연구

Gas hydrate from CO₂/H₂ gas mixtures was formed in a semi-batch stirred vessel at constant pressure and temperature of 280.1K. This mixture is of interest to CO₂ separation and recovery from fuel gas. During hydrate formation the gas uptake was determined and composition change in the gas phase were obtained by gas chromatography. When CO₂/H₂ hydrate formation, the impact of tetrahydrofuran (THF) was observed. The addition of THF not only reduced significantly the operating pressure but also helped to form hydrates easier(shorter induction time). The present study illustrates the concept and provides basic for the separation/recovery of CO₂ (precombustion capture) from a fuel gas(CO₂/H₂) mixture.
