ABSTRACT:
A continuous biofuel production process includes the steps of introducing a feedstock containing fatty acids and triglycerides into a first reaction vessel, in which alkyl esters are produced through esterification of free fatty acids. The alkyl esters and triglycerides are introduced into a second reaction vessel, in which at least a portion of the triglycerides are converted to alkyl esters and glycerin through transesterification. The alkyl esters, glycerin, and remaining triglycerides are introduced into a third reaction vessel, in which at least a portion of the remaining triglycerides are converted to alkyl esters and glycerin through transesterification.
