Abstract
In this paper a comparative study of different plate efficiencies models considering binary systems with association of one component in both phases is presented. The experiments were carried out in a laboratory column with 10 real bubble-cup plates for the benzene—acetic acid and toluene—acetic acid systems. The actual and ideal compositions at each plate are interpreted. The model of associated systems using the concentration-dependent liquid phase association constant was considered.
