Extraction parameters optimization in improving production rate of spent bleaching earth oil

Spent bleaching earth (SBE) is classified as an industrial waste generated by almost all crude palm oil refineries around the globe. SBE contains oil content in the range of 20-40% by weight, which is being extracted out by a solvent extraction process plant to cater for biodiesel production. Most o...
