Evaluation of carbon dioxide absorption by amine based absorbent

AbstractToshiba has developed amine based aqueous solution (Toshiba solvent 1, TS-1) that can significantly reduce CO2 regeneration energy compared with general 30 wt% monoethanolamine (MEA) aqueous solution and reported the results of the pilot plant of 10 t- CO2/day recovery from the flue gas of a coal- fired power plant. In order to reduce the CO2 regeneration energy further, we have developed new hindered amine based absorbent, Absorbent-A.In the present work, Absorbent-A was evaluated for CO2 absorption properties by laboratory scale apparatus. Absorbent-A was found to have the high CO2 absorption capacity and the low reaction heat. Furthermore, the CO2 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

Development of Hindered New Amine Absorbents for CO2 Capture

AbstractAqueous solution containing sterically hindered amine represents candidate solvents having good potential for carbon dioxide (CO2) capture. In the present work, the CO2 reaction with amine-X having sterically hindered substituents in aqueous solution (absorbent-X) is investigated by laboratory scale apparatus. Absorbent-X was found to have the high CO2 cyclic capacity and the low CO2 release temperature. Furthermore, the CO2 regeneration energy of absorbent-X was 45% less than that of general 30 wt% MEA aqueous solution. We will evaluate the absorbent-X at Mikawa pilot plant (10 ton-CO2/day recovery) owned by Toshiba Corp. using the actual flue gas from Mikawa coal fired power plant in Fukuoka prefecture, Japan
