Publication number: 20240076575Abstract: 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.Type: ApplicationFiled: August 23, 2023Publication date: March 7, 2024Applicant: Renewable Energy Group, Inc.Inventors: Martin Haverly, David A. Slade, Jared Downey

Patent number: 10450533Abstract: Methods and devices for economically producing a purified biodiesel product from feedstocks. Some embodiments of the methods 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 crude biodiesel is then subjected to at least one biodiesel refining process which, in conjunction with feedstock pretreatment and free fatty acid refining produces a purified biodiesel product that meets multiple commercial specifications. A wide variety of feedstocks may be used to make biodiesel that otherwise would not meet the same commercial specifications, including corn oil, used cooking oil, poultry fats, fatty acid distillates, pennycress oil, and algal oils.Type: GrantFiled: March 26, 2018Date of Patent: October 22, 2019Assignee: Renewable Energy Group, Inc.Inventors: David A Slade, Cody J Ellens, Bradley N Albin, Derek J Winkel, Jared A Downey

Patent number: 9909077Abstract: The present invention provides a method for producing a refined fatty acid alkyl ester (FAAE) product from feed-stocks containing free fatty acids. The method comprises glycerolysis and transesterification processes combined with end-product refining. Products produced from a transesterification reaction are separated into a crude FAAE stream and a crude glycerin stream. The crude glycerin stream is further processed to produce a glyceride stream from which additional FAAEs may be produced.Type: GrantFiled: July 9, 2014Date of Patent: March 6, 2018Assignee: REG Seneca, LLCInventors: David A. Slade, Derek J. Winkel, Jared A. Downey

Patent number: 9725397Abstract: A system and method for the conversion of free fatty acids to glycerides and the subsequent conversion of glycerides to glycerin and biodiesel includes the transesterification of a glyceride stream with an alcohol. The fatty acid alkyl esters are separated from the glycerin to produce a first liquid phase containing a fatty acid alkyl ester rich (concentrated) stream and a second liquid phase containing a glycerin rich (concentrated) stream. The fatty acid alkyl ester rich stream is then subjected to distillation, preferably reactive distillation, wherein the stream undergoes both physical separation and chemical reaction. The fatty acid alkyl ester rich stream is then purified to produce a purified biodiesel product and a glyceride rich residue stream. The glycerin rich second liquid phase stream may further be purified to produce a purified glycerin product and a (second) wet alcohol stream.Type: GrantFiled: June 21, 2013Date of Patent: August 8, 2017Assignee: REG Seneca, LLCInventors: John P. Jackam, Derek J. Winkel, Jared A. Downey
