An explicit model for carbon dioxide (CO 2 ) solubility in an aqueous solution of 2‐amino‐2‐methyl‐1‐propanol (AMP) has been proposed and an expression for the heat of absorption of CO 2 has been developed as a function of loading and temperature. A rate‐based steady‐state model for CO 2 absorption into an AMP solution has been proposed, using both the proposed expression for the CO 2 solubility and the expression for the heat of absorption along with an expression for the enhancement factor and physicochemical data from the literature. The proposed model has successfully been applied to absorption of CO 2 into an AMP solution in a packed tower and validated against pilot‐plant data from the literature. © 2006 American Institute of Chemical Engineers AIChE J, 2006
