It is necessary to have rectifier in NH<sub>3</sub>-H<sub>2</sub>0 absorption cycle in order to remove steam from ammonia and steam mixed vapor that is regenerated in generator. Although many studies have made to investigate the performance of rectifier using various fluids experimentally, few theoretical analysis has made without any constant from experimental data.<br>In this study in order to investigate the characteristic of rectifying process, experimental and analytical approach was made concerning plate-type rectifier. In the experiment, the effect of vapor flow rate and NH<sub>3</sub> mass concentration of solution on rectifying performance were investigated. And in the analysis the model of heat and mass transfer was proposed considering the distribution of mass concentration in boundary layer. As a result it was found that NH<sub>3</sub> mass concentration at rectifier outlet slightly decreased as vapor flow rate increased and that the model could predict NH<sub>3</sub> mass concentration in outlet vapor for various concentration in solution.
