An apparatus 10 for separating out biodiesel and glycerol from a mixture of biodiesel and glycerol and/or a reacting mixture of base oil and alcohol comprises a vat 12 in which a hydrocyclone 76 is disposed. The hydrocyclone has a downwardly-pointing generally-conical wall 80, an inlet port 84 adjacent the top of the hydrocyclone which is fed by an inlet passageway 86 so that the process liquid is fed tangentially into the hydrocyclone. A lower, downwardly-directed outlet port 92 adjacent the bottom of the hydrocyclone, and an upper, upwardly-directed outlet port 92 adjacent the top of the hydrocyclone. A bottom outlet passageway 116 adjacent the bottom of the vat and an optional upper outlet passageway 150 adjacent the top of the vat can be used to drain glycerol and biodiesel from the vat, and a middle outlet passageway part-way up the vat can be used to recirculate process liquid back to the inlet passageway. |
