Effect of Stirring Rate and Freezing Time on the Percentage of Recovery of Residual Oil from Palm Oil Mill Effluent via a Stirred Freeze Crystallizer

In palm oil industries, treating palm oil mill effluent (POME) is still problematic due to both technologies sustainability and management will. In conjunction with the POME problem, increasing the oil extraction rate (OER) is also the most crucial task for these palm oil production community. The m...
