Equilibrium staged parametric pumping. I. Single transfer step per half‐cycle and total reflux—the analogy with distillation

Abstract

AbstractEquilibrium staged batch parametric pumps are studied with nonlinear isotherms. The half cycle is composed of one single equilibration step and one discrete transfer. The limiting regime (for infinite number of cycles) is shown to correspond to a staircase construction between the two isotherms, the number of steps being equal to the number of stages. The reservoir concentrations are then connected by Fenske's equation. Several analogies with binary total reflux distillation are suggested.
