Bio-LNG supply chain mainly consists of CO2 removal unit and then liquefaction process. Conventionally, CO2 is removed through amines-based absorption, which consumes huge energy to regenerate the amines-based solvent. Similarly, liquefaction of bio-natural gas also uses the tremendous amount of energy in refrigeration cycle. Therefore, bio-LNG production is an energy and cost intensive process. In this context, we propose an energy efficient CO2 removal through ionic liquid [Bmim][PF6], by screening of leading candidates, rigorous regression and experimental validation of ionic liquids, followed by optimized energy efficient bio-LNG production process.
