Fractionation of palm kernel oil by short path distillation

Fractionation of palm kernel oil (PKO) by short path distillation (SPD) at two feed flow rates (135 g/h and 195 g/h) and six distillation temperatures, TDis (200, 210, 220, 230, 240 and 250 °C) was investigated. Other distillation parameters, such as vacuum pressure (0.001 mbar), blade rotation spee...
