An extended Redlich-Kwong equation of state, with two adjusted parameters on each pure component vapour pressure curve, and four mixture parameters, is shown to give a good representation of vapour-liquid equilibria for the ammonia-water system. The mixing parameters are obtained from the data of Guillevic, Pawlikowski and Scatchard. Other data, including enthalpies, are satisfactorily predicted. Using these parameters, heat pump systems can easily be designed using the Aspen Plus flow-sheeting program.
