【 摘 要 】

References(6)Cited-By(1)2-(Isopropylamino)ethanol-based solvent for carbon dioxide (CO2) capture from coal-fired flue gas was evaluated through pilot plant tests and process simulation. A 10 t-CO2/d-scale pilot plant was operated at various conditions of liquid-to-gas ratio and steam feed rates. Also, a process simulation was carried out to estimate CO2 recovery and the thermal energy requirement for the chemical absorption process. As a result, the minimum energy requirement of the solvent for CO2 capture was 3.0 GJ/t-CO2 at 90% CO2 recovery in the pilot plant operation. The process simulation also showed the potential of the solvent which could reduce the energy requirement by 30% compared with a monoethanolamine (MEA) 30 wt% aqueous solution.
