NOVELTY - Production (M1) of purified biodiesel from a feedstock involves: reacting glycerides with at least one alcohol to produce a fatty acid alkyl ester stream; purifying the fatty acid alkyl ester stream by distillation, where the distillation involves separating the fatty acid alkyl ester stream into a purified fatty acid alkyl ester stream and at least second stream; and recovering fatty acid alkyl esters from the purified fatty acid alkyl ester stream.    USE - For production of purified biodiesel from a feedstock (claimed).    ADVANTAGE - The purified fatty acid alkyl ester stream or second fatty acid alkyl ester stream has reduced levels of at least one of impurity, unsaponifiable material, glycerin, monoglyceride, diglyceride, triglyceride, and free fatty acid relative to the fatty acid alkyl ester stream.    DETAILED DESCRIPTION - Production (M1) of purified biodiesel from a feedstock involves: either process (A): reacting glycerides with at least one alcohol to produce a fatty acid alkyl ester stream; purifying the fatty acid alkyl ester stream by distillation, where the distillation involves separating the fatty acid alkyl ester stream into a purified fatty acid alkyl ester stream and at least second stream; and recovering fatty acid alkyl esters from the purified fatty acid alkyl ester stream; or process (B): reacting glycerides with at least one alcohol to produce a first fatty acid alkyl ester stream; separating the first fatty acid alkyl ester stream from high-boiling point impurities according to differences in vapor pressure to create at least a second fatty acid alkyl ester stream; and recovering fatty acid alkyl esters from the second fatty acid alkyl ester stream. INDEPENDENT CLAIMS are included for the following:    (1) product produced by the method (M1), (M2) and (M3);    (2) production (M2) of purified biodiesel from a feedstock involving: i) reacting glycerides with at least one alcohol to produce a first fatty acid alkyl ester stream; ii) purifying the first fatty acid alkyl ester stream by distillation, where the distillation involves separating an overhead fraction from the first fatty acid alkyl ester stream to recover a second fatty acid alkyl ester stream; iii) purifying the second fatty acid alkyl ester stream by distillation, where the distillation involves separating the second fatty acid alkyl esters from a bottoms fraction; and iv) recovering purified fatty acid alkyl esters; and    (3) producing (M3) purified biodiesel involving: conditioning of a fatty acid containing feedstock by heating, mixing and filtering to create a conditioned feedstock; reacting the conditioned feedstock with alcohol to produce fatty acid alkyl esters and glycerin; separating the fatty acid alkyl esters from the glycerin to yield a fatty acid alkyl ester rich stream and a glycerin rich stream; purifying the fatty acid alkyl ester rich stream by distillation; and recovering purified fatty acid alkyl esters.
