Abstract:
1. A method of making biodiesel fuel in a biodiesel plant for making the biodiesel fuel, the plant comprising: (i) a closed loop reaction chamber having an inlet and an outlet, wherein the closed loop reaction chamber comprises a closed loop flow path, the inlet and outlet being disposed along the closed loop flow path; (ii) means for circulating reactants through the reaction chamber such that portions of the reactants will pass along the loop from the inlet, past the outlet and back past the inlet for mixing with the other portions of the reactants entering at the inlet; (iii) means for causing turbulent flow of the reactants through the reaction chamber, wherein the method comprises the steps of: a) heating the reactants; b) mixing the heated reactants in the reaction chamber by causing turbulent flow thereof through the reaction chamber causing the reactants to react and form reacted reactants; c) further circulating the reactants and the reacted reactants in the reaction chamber along the closed loop from the inlet, past the outlet and back past the inlet for mixing with other portions of the reactants entering at the inlet such that at least some reactants and reacted reactants will flow around the reaction chamber multiple times and mix with reactants entering at the inlet; and d) removing the reacted reactants from the outlet, the reacted reactants comprising crude biodiesel fuel, and allowing the crude biodiesel fuel to settle.
