  • Co2 Capture From Lime Kiln Using Ampda2mp Amine Solvent

    CO 2 capture from lime kiln using a benchscale pilot plant was studied.. Comparative analysis between MEA and AMPDA2MP blend was investigated. The CO 2 capture efficiency and mass transfer coefficient of AMPDA2MP is higher than that of MEA.. The AMPDA2MP blend has lower regeneration energy compared to MEA.
