Heat requirement of CO2 absorption by aqueous ammonia
Konferensbidrag (offentliggjort, men ej förlagsutgivet), 2011

Aqueous ammonia has lately emerged as a promising absorbent of CO2 in post-combustion capture applications, often referred to as the chilled ammonia process (CAP). The heat required for regeneration, i.e. the reboiler duty (kJ/kg CO2), is a crucial parameter for all absorbents. For the CAP, the required reboiler duty presented in literature ranges from 1,500 to 4,200 kJ/kg CO2 [1-6]. This is a wide range with crucial consequences for the feasibility of the process. The aim of this work is to review the different sources in order to explain the large difference in heat requirement.
