| Popis: | Toshiba has developed amine based aqueous solution (Toshiba solvent 1, TS-1) that can significantly reduce CO 2 regeneration energy compared with general 30 wt% monoethanolamine (MEA) aqueous solution and reported the results of the pilot plant of 10 t- CO 2 /day recovery from the flue gas of a coal- fired power plant. In order to reduce the CO 2 regeneration energy further, we have developed new hindered amine based absorbent, Absorbent-A. In the present work, Absorbent-A was evaluated for CO 2 absorption properties by laboratory scale apparatus. Absorbent-A was found to have the high CO 2 absorption capacity and the low reaction heat. Furthermore, the CO 2 regeneration energy of Absorbent-A was 45% less than that of general 30 wt% MEA aqueous solution. In future, we will additionally evaluate Absorbent-A in order to test in the pilot plant. |
