Abstract

The primary goal of this work is to present a systematic methodology and software frameworkfor a multi-level approach ranging from process synthesis and modeling throughproperty prediction, to sensitivity analysis, property parameter tuning and optimization.This framework is applied to the following selected oleochemical processes: vegetableoil splitting, fatty acid fractionation and glycerol purification. The framework includesthe prediction of physical and thermodynamic properties and the uncertainties of the estimatedvalues coupled with the process model represented by mass and energy balances.The effects of these uncertainties are assessed with sensitivity analysis. Standardized regressioncoefficients (SRC) are evaluated and Sobol analysis is performed to study thecounter-current spray splitting column and rank each model parameter. The informationobtained is used for the tuning of property models, optimization of process flowsheets andanalysis of the overall process by multi-criteria sustainability and economics analysis.
