摘要：

AMP has for many years been considered a good absorbent for CO2 and in particular in mixtures with promoters as e.g. piperazine. AMP, as a primary amine, can form carbamate but steric hindrance prevents extensive formation. Its effect on equilibrium is not widely investigated and only one set of measurements for a single temperature is available. In this work the AMP carbamate formation constant is calculated using computational chemistry and a model based on the extended UNIQUAC framework is used to model partial pressures, speciation and heat of absorption. Also a set of measured differential heats of reaction are presented. (c) 2013 Elsevier Ltd. All rights reserved.
