PARAMETRIC ANALYSIS OF DIRECT-CONTACT EVAPORATION PROCESS IN A BUBBLE-COLUMN

This paper presents a detailed analysis of the influence of several im portant parameters, such as the breakage of droplets, the driving temp erature difference, the initial mean diameter of drops from the bottom distributor, and the maximum diameter of stable drobbles on the direc t-contact evaporation process in a bubble column. Some simulation resu lts agree with experimental data reasonably well. Numerical calculatio ns show that there is an approximately proportional relationship betwe en the evaporation height and the reciprocal of the driving temperatur e difference.
