Analysis of Flow, Pressure Drop, and Power Requirement in Pulsed Columns

A model is developed for liquid pulsed columns and reciprocating plate columns by considering the column and the peripheral lines attached to it as comprising an interacting system. Similarities and differences between the two types of pulsed columns are brought out by comparing the equations set up to describe them. The model predicts the instantaneous and time-averaged (i) fluid velocity, (ii) pressure drop, (iii) power dissipated in the column, (iv) power required to provide pulsation, and (v) power required to pump the fluid(s) through the column for single-phase flow and two-phase flow. Verification of the model is done by comparing model results with the experimental data available in literature as well as the data obtained in the present study using a reciprocating plate column. © 1992, American Chemical Society.
