Gas purification system modeling in fatty acids removing from soapstock

Based on the material equations and heat balances, we developed a mathematical model of the technological process for extraction of fatty acids from soapstock accompanied by the release of the gas-vapor mixture at chemical transformations by the example of soapstock decomposition in sulfuric acid. The mathematical model takes into account multi-component mixtures and allows one to determine the parameters of the process in relation to the ideal and non-ideal systems. The solution of the system is carried out using the developed modeling algorithm on a computer specialized software. Analysis of the modeling results provides the opportunity to evaluate the impact of the decomposition process parameters on the evaporation rate, to identify the kinetic parameters of the technological processes accompanied by chemical transformations and evaporation. With a sufficient certainty, the developed mathematical model also allows one to choose the technical solutions to reduce toxic emissions into the atmosphere, to determine the optimal conditions for fatty acid extraction process from soapstock, set the parameters which significantly intensify the process as well as to develop new plant designs and improve existing technologies. The resulting mathematical model is used to calculate the technological schemes implemented in various enterprises located in the territory of the Russian Federation.
