Phase equilibria of mixtures involving fatty acid ethyl esters and fat alcohols between 4 and 27 kPa for bioproduct production

The aim of this paper is to bring valuable phase equilibria information for the design and operation biolubricant related biofuel product processes. As a result, Vapor-Liquid Equilibrium (VLE) measurements, at different temperatures, pressures global compositions, ternary systems [Ethanol + 2-Ethyl-1-hexanol 1-Dodecanol] 1-Octanol 1-Dodecanol], as well multicomponent system containing these alcohols together with Balanites aegyptiaca fatty acid ethyl esters are reported first time (data pressure temperature ranges: 4394–26790 Pa, 306–423 K). Dortmund modified UNIFAC model showed very high accuracy in prediction VLE, overall average absolute deviations on liquid vapor molar compositions 0.007 0.0003 systems, 0.003 0.006 system.
