Simple functions for fast calculations of selected thermodynamic properties of the ammonia-water system.

Author(s) : PATEK J., KLOMFAR J.

Type of article: Article, IJR article

Summary

A set of five equations describing vapour-liquid equilibrium properties of the ammonia-water system is presented. They are intended for use in the design of absorption processes and they make it possible to avoid iterative evaluations. They were constructed by fitting critically assessed experimental data using simple functional forms and they cover the region within which absorption cycles commonly used operate most often. The enthalpy of the gas phase has been calculated in the ideal mixture approximation. The results are presented in the form of an enthalpy-concentration diagram.
