20110162953 | RECOVERY OF BUTANOL FROM A MIXTURE OF BUTANOL, WATER, AND AN ORGANIC EXTRACTANT - A process for recovering butanol from a mixture comprising a water-immiscible organic extractant, water, butanol, and optionally a non-condensable 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 comprising butanol and a second bottoms stream comprising the extractant. The extractant comprises at least one solvent selected from the group consisting of C | 07-07-2011 |
20110162954 | RECOVERY OF BUTANOL FROM A MIXTURE OF BUTANOL, WATER, AND AN ORGANIC EXTRACTANT - A process for recovering butanol from a mixture comprising a water-immiscible organic extractant, water, butanol, and optionally a non-condensable 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 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 comprises at least one solvent selected from the group consisting of C | 07-07-2011 |
20110288344 | RECOVERY OF BUTANOL FROM A MIXTURE OF BUTANOL, WATER, AND AN ORGANIC EXTRACTANT - A process for recovering butanol from a mixture comprising a water-immiscible organic extractant, water, butanol, and optionally a non-condensable gas, is provided. The butanol is selected from 1-butanol, 2-butanol, isobutanol, and mixtures thereof. An overhead stream from a first distillation column is condensed to recover a mixed condensate. An entrainer is added to at least one appropriate process stream or vessel such that the mixed condensate comprises sufficient entrainer to provide phase separation of the organic and the aqueous phases to provide for recovery of the butanol. | 11-24-2011 |
20110288345 | RECOVERY OF BUTANOL FROM A MIXTURE OF BUTANOL, WATER, AND AN ORGANIC EXTRACTANT - A process for recovering butanol from a mixture comprising a water-immiscible organic extractant, water, butanol, and optionally a non-condensable gas, is provided. The butanol is selected from 1-butanol, 2-butanol, isobutanol, and mixtures thereof. The extractant comprises at least one solvent selected from the group consisting of C | 11-24-2011 |

An entrainer is added to at least one appropriate process stream or vessel such that the mixed condensate comprises sufficient entrainer to provide phase separation of the organic and the aqueous phases to provide for recovery of the butanol. | 01-03-2013 |
20130001062 | RECOVERY OF BUTANOL FROM A MIXTURE OF BUTANOL, WATER, AND AN ORGANIC EXTRACTANT - A process for recovering butanol from a mixture comprising a water-immiscible organic extractant, water, butanol, and optionally a non-condensable gas, is provided. The butanol is selected from 1-butanol, 2-butanol, isobutanol, and mixtures thereof. The extractant comprises at least one solvent selected from the group consisting of C | 01-03-2013 |
20130252297 | Method for Controlling Butanol Concentration in Fermentation Broth - The present invention relates to a two stage process to control the butanol concentration from fermentation broth. | 09-26-2013 |
20140018581 | Process to Remove Product Alcohol from a Fermentation by Vaporization under Vacuum - A fermentation liquid feed including water and a product alcohol and optionally CO | 01-16-2014 |

20150080615 | HIGH TEMPERATURE ESTER HYDROLYSIS OPERATING AT HIGH ESTER TO WATER RATIOS - 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. | 03-19-2015 |
20150087040 | PRODUCTION OF ETHANOL AND RECYCLE WATER IN A CELLULOSIC FERMENTATION PROCESS - 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. | 03-26-2015 |
20150087041 | PRODUCTION OF ETHANOL WITH REDUCED CONTAMINANTS IN A CELLULOSIC BIOMASS BASED PROCESS - 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. | 03-26-2015 |
