LNG 발전배가스 농축 CO₂를 이용한 액화 실증기술의 개발

Development of liquefaction demonstration technology using CO₂ concentrated from LNG power generation exhaust gas

Liquified carbon dioxide (LCO₂) is a promising alternative to fossil fuels that can be used to reduce greenhouse gas emissions. There is growing research into the use of liquefied CO₂ (LCO₂) to reduce CO₂ emissions, which can be transported deep underground for carbon capture and storage (CCS) and LCO₂ for enhanced oil recovery (EOR). It can be used to extract additional oil by injecting it into oil fields, and can also be used as a raw material and refrigerant for the production of various fuels. This study attempted to conduct an empirical study on the production of LCO₂ with a purity of 90% or higher targeting concentrated CO₂ from LNG flue gas. This study was designed to secure empirical process development technology applicable to existing LNG power generation infrastructure and reduce greenhouse gas emissions in the future and reduce cliinate change. It is expected that it will make a significant contribution to mitigating the impact.
