Abstract: The present disclosure is directed to methods, approaches, devices, equipment, and systems for minimizing or reducing contamination in facilities implementing fermentation or distillation processes. In embodiments, the facility is a biofuel plant that produces fermentation product such as product alcohol like butanol. In some embodiments, the methods, approaches, devices, equipment, and systems are operable to implement clean in place contamination (CIP) mitigation techniques that can also include sterilize in place (SIP) mitigation techniques to decontaminate equipment including surfaces of the equipment that come in contact with materials used in the production of product alcohols. Other cleaning and contamination minimizing techniques are also described.

Abstract: The present invention relates to processes to remove butanol and other product alcohols from a fermentation broth employing vacuum vaporization.

Abstract: The present invention relates to processes for recovering butanol produced in a fermentative process using, for example, an ethanol production plant which has been reversibly-retrofitted for butanol production, that is, the ethanol production plant may be converted for butanol production, but can also revert to an ethanol production. The present invention also relates to processes for recovering butanol produced in a fermentative process in a butanol production plant that may be converted to ethanol production plant.

Abstract: A method and system for efficiently producing a fermentative product alcohol such as butanol utilizing in situ product extraction are provided. The efficiency is obtained through separating undissolved solids after liquefying a given feedstock to create a feedstock and prior to fermentation, for example, through centrifugation. Removal of the undissolved solids avoids problems associated with having the undissolved solids present during in situ production extraction, and thereby increases the efficiency of the alcohol production.

Abstract: Provided herein are methods for recovering butanol from a fermentation medium. The methods comprise providing a fermentation medium comprising butanol, water, and a recombinant microorganism comprising a butanol biosynthetic pathway, wherein the recombinant microorganism produces butanol; contacting the fermentation medium with a water immiscible organic extractant composition comprising a dry solvent to form a butanol-containing organic phase and an aqueous phase; and recovering the butanol from the butanol-containing organic phase.

Abstract: 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.
