Abstract

This work investigated the suitability of biodiesel (predominantly Methyl Linolenate, Methyl Palmitate, Methyl Oleate and Methyl Stearate) as an absorbent for the recovery of VOCs from waste gas process streams through absorption. The objective was to predict the vapour liquid equilibria (VLE) data in the form of infinite dilution activity coefficients for five VOC families, in fatty acid methyl ester solvents at varying temperature. The Original Universal Functional Group Activity Coefficient (UNIFAC) model (Fredenslund et al., 1975) [1], Modified UNIFAC (Larsen et al., 1981) [2] and Modified UNIFAC (Bastos et al., 1988) [3] was used to predict the required phase equilibrium. Alkanes, alcohols and acids/ester interactions showed an increase in activity coefficients with increase in temperature. The influence of temperature on the activity coefficients for alkene and amine families was negligible. The solubility of VOCs in biodiesel decreases with increase in ester hydrocarbon unsaturation. The solubility of VOCs increased with increase in ester molecular weight.
