Development of an ammonia based PCC technology for Australian conditions: technical report no. 2
24th January 2014
The size and cost of a CO2 capture plant will be directly related to the absorption and separation properties of the capture solvent used. For power generation purposes, commercially available post combustion capture technology is currently considered using amine based solutions, which are estimated to result in about 10% efficiency loss from power plants. This project investigates the potential of using aqueous ammonia as a low energy consuming, high CO2 absorption capacity alternative, with several other associated benefits. Six (6) chemical promoters were tested and the preliminary results show that with the aid of the promoters the mass transfer coefficient of CO2 more than doubled.
