Abstract:
Study on fish oil Supercritical Fluid Fractionation (SFF) is still an open issue with the objective of large scale production. A fundamental issue for scaling up the process is the knowledge of phase behaviour of the mixtures involved in SFF. So, development of reliable models to describe phase behaviour of the mixtures is crucial. Some thermodynamic models have been suggested which is able to predict solubility of fatty acid ethyl esters in supercritical phase. Some relevant experimental data is necessary to fit and validate the models. In this work, the experiments are designed to collect equilibrium data in the FeyeCon pilot plant. A validated model becomes a fundamental tool for the process design and optimization. The ultimate goal of this project is to optimize the Supercritical Fluid Fractionation (SFF) process of Fatty Acid Ethyl Ester (FAEE) mixture sourced from fish oil. Finally, the plant will be designed for some different throughputs. This provides an estimating of the investment costs in order to outline a preliminary process feasibility evaluation
