Publication number: 20160002131Abstract: Provided are processes for recovering thermal energy and utilizing the recovered thermal energy as a heat source. The processes comprise distilling a butanol and water composition in a distillation unit, whereby the distillation produces a vapor comprising butanol and water at a pressure P1; compressing the vapor to a second pressure P2, wherein P2 is greater than P1; and condensing the vapor to a liquid, whereby condensing the vapor allows for the recovery of thermal energy, wherein the recovered thermal energy is used as a heat source.Type: ApplicationFiled: February 14, 2014Publication date: January 7, 2016Inventors: Michael Glasspool, William D. Parten, Joseph J. Zaher

Publication number: 20150087041Abstract: Processes for producing ethanol from fermentation systems employing cellulosic feedstocks are provided, where contaminants prevalent from biomass hydrolysate fermentation are managed. The management of contaminants allows recycle of process water between the fermenter vent scrubber and rectification column, thereby removing the need for fresh water to the scrubber.Type: ApplicationFiled: September 26, 2013Publication date: March 26, 2015Applicant: E I DU PONT DE NEMOURS AND COMPANYInventor: WILLIAM D. PARTEN

Publication number: 20150087040Abstract: Processes for producing ethanol from fermentation systems employing cellulosic feedstocks are provided, where water is processed for recycle. The water handling portion of the process employs multi-effect evaporators where the first effect evaporator is maintained at temperatures in excess of 105° C., and the evaporation train, beer column form a heat integrated system.Type: ApplicationFiled: September 26, 2013Publication date: March 26, 2015Applicant: E I DU PONT DE NEMOURS AND COMPANYInventors: William D. Parten, Rahul B. Kasat

Publication number: 20150080615Abstract: A process for recovering alcohol from a fatty acid and/or diacid alcohol ester using water in an equal or lesser amount than oil on a mass basis. The process uses multiple reactors with separation of the alcohol product of hydrolysis between successive reactors. The use of low amounts of water allows recovery of the alcohol with a lower evaporation requirement, thus making a more energy efficient process.Type: ApplicationFiled: September 12, 2014Publication date: March 19, 2015Inventors: STUART B. FERGUSSON, LARIN GODFROY, MICHAEL CHARLES GRADY, DAVID F. KRAYNIE, WILLIAM D. PARTEN, STEPHEN M. TIERI

Patent number: 8968522Abstract: A process for recovering butanol from a mixture of a water-immiscible organic extractant, water, butanol, and optionally a noncondensable gas, is provided. The butanol is selected from 1-butanol, isobutanol, and mixtures thereof An overhead stream from a first distillation column is decanted into two liquid phases. The wet butanol phase is returned to the first distillation column as reflux. A bottom stream from the first distillation column is refined in a second distillation column to obtain a second overhead stream and a second bottoms stream. The extractant may be C7 to C22 fatty alcohols, C7 to C22 fatty acids, esters of C7 to C22 fatty acids, C7 to C22 fatty aldehydes, and mixtures thereof.Type: GrantFiled: July 13, 2010Date of Patent: March 3, 2015Assignee: Butamax Advanced Biofuels LLCInventors: Yihui Tom Xu, William D.

The butanol is selected from 1-butanol, isobutanol, and mixtures thereof. An overhead stream from a first distillation column is decanted into two liquid phases. The wet butanol phase is refined in a second distillation column; the aqueous phase is returned to the first distillation column. A portion of the wet butanol phase from the decanter is also returned to the first distillation column. The extractant may be C7 to C22 fatty alcohols, C7 to C22 fatty acids, esters of C7 to C22 fatty acids, C7 to C22 fatty aldehydes, and mixtures thereof.Type: GrantFiled: July 13, 2010Date of Patent: March 3, 2015Assignee: Butamax Advanced Biofuels LLCInventors: Yihui Tom Xu, William D.

Publication number: 20140099688Abstract: A fermentation liquid feed including water and a product alcohol and optionally CO2 is at least partially vaporized such that a vapor stream is produced. The vapor stream is contacted with an absorption liquid under suitable conditions wherein an amount of the product alcohol is absorbed. The portion of the vapor stream that is absorbed can include an amount of each of the water, the product alcohol and optionally the CO2. The temperature at the onset of the absorption of the vapor stream into the absorption liquid can be greater than the temperature at the onset of condensation of the vapor stream in the absence of the absorption liquid. The product alcohol can be separated from the absorption liquid whereby the absorption liquid is regenerated. The absorption liquid can include a water soluble organic molecule such as an amine.Type: ApplicationFiled: December 6, 2013Publication date: April 10, 2014Applicant: BUTAMAX ADVANCED BIOFUELS LLCInventors: Michael Charles Grady, William D. Parten, Robert W. Sylvester, Joseph J. Zaher
