摘要

Abstract

This article deals with the evaluation of the consumption of energy for a steady state solvent extraction in a novel L-shaped pulsed sieve-plate column

which is highly required for design and optimization of the periodic flow processes for industrial applications. In this regard

a comprehensive evaluation on the energy consumption in case of a pulsed flow for three different chemical systems is conducted and besides the influence of pulsation intensity

the effect of geometrical parameters including the plate spacing and the plate free area is investigated as well. Moreover

the concept of characteristic velocity models at flooding points is evaluated with respect to the variation of pressure drop along the column at different operational conditions.
