Abstract
ABSTRACT Raw biodiesel usually contains a considerable amount of impurities that need to be separated. In this work, a 10-mm diameter Dorr-Oliver hydrocyclone was used to investigate the separate behavior of impurities from biodiesel prepared from waste cooking oil under different operational conditions. The experimental results showed a maximum impurity separation of 82.2% (v/v). The operational conditions including inlet mixture temperature, pressure drop across the hydrocyclone, and the percentage of inlet impurities were optimized using Taguchi method. Then, the hydrocyclone was modeled using CFD to optimize its dimensions. The experiments performed by the optimized hydrocyclone indicated an impurities separation of 90.76%.
