Process design and optimization of palm oil from spent bleaching earth via supercritical extraction

Vegetable oil recovery from spent bleaching earth (SBE) has various advantages which exist in the vegetable oil industry for cost saving and cleaner production. Vegetable oils go through several steps to eliminate unenviable compounds and produce stable and high-quality products. There are several disadvantages associated with Palm Oil extraction from conventional methods which involve multiple unit operation, complex separation steps, hazardous chemical, energy-intensive operations potential of producing large quantities of wastes and water. Therefore, the objective of study is to develop a process simulation and optimization for the recovery of palm oil from spent bleaching using supercritical fluid extraction (SFE). The methodology adopted for this study include applying industrial data to enable the development of a reliable simulation and optimization models of the supercritical fluid extraction to recover palm oil from spent bleaching earth. The simulation and optimization for obtaining palm oil from spent bleaching earth via SFE will produce comparable and better oil recovery, using a significantly intensified process that is green and sustainable
