Ideal thermodynamic efficiency equation for continuous distillation of
ideal binary mixture
Abstract
Determining the conversion efficiency of thermal exergy into the work of
separation is of great importance for distillation process. In this
study, an ideal thermodynamic efficiency equation not containing
physical property data was proposed for calculating the thermodynamic
efficiency of the continuous distillation process of ideal binary
mixture. Benzene-toluene mixture was taken as an ideal binary mixture,
and the accurate and approximate thermodynamic efficiencies of the
continuous distillation of benzene-toluene ideal mixture were calculated
by the thermodynamic efficiency equation based on the relevant physical
property data and the proposed ideal thermodynamic efficiency equation,
respectively. The results showed that the difference between the
calculated thermodynamic efficiencies was less than 5%, demonstrating
the feasibility of calculating the thermodynamic efficiency of the
continuous distillation process of ideal binary mixture using the ideal
thermodynamic efficiency equation.
