A process for the generation of renewable fuel and/or biofuel from a renewable oil feedstock having a high free fatty acid content. The renewable oil feedstock can be renewable plant oil or renewable animal fat or oil, including renewable corn oil recovered from a by-product of ethanol production, such as distillers corn oil and/or corn oil solvent extracted from distillers dried grains with solubles (DDGS) and/or distillers dried grains (DDG). The free fatty acid content of the renewable oil feedstock can be reduced by a glycerolysis process in the presence of a molar excess of glycerin to provide an adequate resulting feedstock having a reduced free fatty acid content. The resulting feedstock capable of being subjected to further processing for the generation of renewable fuel and/or biofuel.

Methods and apparatus for economically producing a biodiesel product from feedstocks. Some embodiments comprise using at least one of a crude feedstock pretreatment process and a free fatty acid refining process prior to transesterification and the formation of crude biodiesel and glycerin. The free fatty acid refining process may include introducing the feedstock to glycerolysis to obtain a glycerolysis product then stripping the glycerolysis product to produce a fatty acid distillate and a stripped feedstock. The fatty acid distillate is recycled to the glycerolysis process to create more higher-molecular weight glycerides and the stripped feedstock (mostly di- and tri-glycerides) proceeds to transesterification to make biodiesel.
