|Title:||Steam Deacidification Of The Model System Of Refined Palm Stearin + Refined Palm Olein + Oleic Acid|
|Abstract:||Palm oil is one of the major vegetable oil sources and currently the world palm oil production has reached 41.12 million of metric tons. Only a small number of crude fats and oils is suitable for human consumption before it has been processed in some manner. Deodorization and/or physical refining are mass transfer purification process based on the large differences in volatility between the oil and the majority of its unwanted substances and are accomplished by applying high temperatures and low pressures. Then, this work aimed to verify the effects of three operating parameters i.e., final oil temperature (ranging from 200°to 260°), steam flow (from 0.5% to 6.5%) and stearin/olein ratio (from 0.10% to 0.90%) in the removal of the acidity, following a 23 factorial design. The model system was composed by refined palm stearin + refined palm olein+ oleic acid. It also aimed to validate the simulation tool by comparison between experimental results and computational ones. The composition of the model system, an input of the simulation program, was considered in a rigorous way. The effects of process variables upon the selected response, final oil acidity were evaluated. The comparison between the experimental and the simulation results revealed a satisfactory approximation with a mean relative deviation of 16.10%. These results showed that a computational simulation program can be used as a tool to perform previous studies about processing conditions in an industrial plant.|
