More Information
Summary:This invention is directed to methods for recovery of C3-C6 alcohols from dilute aqueous solutions, such as fermentation broths. Such methods provide improved volumetric productivity for the fermentation and allow recovery of the alcohol. Such methods also allow for reduced energy use in the production and drying of spent fermentation broth due to increased effective concentration of the alcohol product by the simultaneous fermentation and recovery process which increases the quantity of alcohol produced and recovered per quantity of fermentation broth dried. Thus, the invention allows for production and recovery of C3-C6 alcohols at low capital and reduced operating costs. La présente invention concerne des procédés de récupération d'alcools C3-C6 à partir de solutions aqueuses diluées, telles que des bouillons de fermentation. De tels procédés améliorent la productivité volumétrique en vue de la fermentation et permettent la récupération de l'alcool. De tels procédés permettent également de réduire l'utilisation d'énergie au cours de la production et du séchage du bouillon de fermentation utilisé, en raison d'une concentration efficace supérieure du produit alcoolique grâce à la simultanéité de la fermentation et du processus de récupération, ce qui augmente la quantité d'alcool produite et récupérée par quantité de bouillon de fermentation séché. Ainsi, l'invention permet la production et la récupération d'alcools C3-C6 avec des coûts d'immobilisation du capital et d'exploitation réduits.
