Análise de sensibilidade paramétrica do processo de degomagem do óleo de soja utilizando o software Aspen HYSYS

Abstract

The soybean is one of the most important crops in the world and the products derived from it are of great importance to the national economy. The soybean oil produced in the industry must be refined after its extraction. The first is degumming, which removes the hydratable phosphatides from the crude oil. The aqueous form of this process was studied using computer experiments and Aspen HYSYS simulation software. Starting from maximizing the removal of hydratable phosphatides (HP), an analysis of the influence of the process operating parameters was performed. After designing this refining step in the simulator, the obtained results show that for the parameters related to the oil quality (hydration percentage and amount of HP in the crude oil), the simulation shows a similar behavior as expected in the literature and found in industrial processes in this sector. Moreover, for the industrial scenario, a reliable production capacity for degummed oil was demonstrated considering the percentage of phosphatides removed. For the temperature and pressure parameters, it was not possible to obtain an accurate representation of the performance expected in the literature. Through this work, it was possible to identify the behavior and influence of the process parameters that can facilitate the optimization of the extraction of HP from degummed oil.
