Mathematical modeling of deodorization process for a cross current multistage deodorizer

Abstract

Deodorization of fats and oils is necessary to remove the undesirable flavor and odor components that are naturally present or created during processing. A mathematical formula was derived to establish the relationship between the initial and final concentration of free fatty acids entering and leaving the deodorizer, pure vapor pressure of volatile component at each stage, oil molar flow rate and total system pressure. The experimental data were compared with theoretical data using MATLAB graphical tool for data gathered from industrial deodorizer of 200TPD for a period of 6months. The types of oils tested are crude palm oil (CPO) and hydrogenated palm oil (HPO).
