Definitions

  • Vinasse is an aqueous waste product produced while making ethanol by fermentation.
  • the term vinasse is often applied to waste produced when making fuel ethanol from sugarcane.
  • similar waste products are produced when making fuel ethanol from other feedstock such as sugar beet or corn, when producing drinking alcohol, and when making wine.
  • a similar waste product may be called spent wash, slop, stillage, dunder, wet distiller's grains with solubles (WDGS) or other words.
  • WDGS wet distiller's grains with solubles
  • the word vinasse will be used to include waste produced when making fuel ethanol from sugarcane and other similar aqueous waste products from alcohol production unless a specific source of the vinasse is specified.
  • Vinasse has high concentrations of organic and inorganic matter. Vinasse has been applied as fertilizer to fields near distilleries. However, the organic compounds in the vinasse decompose on the land and create offensive odors. Further, unless vinasse is applied at a low rate, the amount of salts provided by the vinasse is more than the plants can take up. The soil becomes saturated over time which results in lower crop yields and, in some cases, groundwater or surface water contamination. As distilleries continue or expand their operations, the vinasse must be trucked longer distances to avoid saturating local fields and the trucking costs become prohibitive. Vinasse trucking costs for an average size mill can exceed $1000 (US) per hour of production.
  • the vinasse may be condensed in an evaporator to reduce trucking costs.
  • an evaporation plant in Karnataka uses an evaporator to increase solids concentration from 12 to about 55-60 wt%.
  • the evaporator consumes energy.
  • the distillate has a high concentration of organic contaminants and is recycled to the fermenter.
  • a system for treating vinasse described in this specification combines an anaerobic digester, a membrane bioreactor and a salt concentrator such as an
  • the anaerobic digester is placed upstream of the membrane bioreactor which is upstream of the concentrator.
  • an anaerobic digester consumes part of the organic matter in vinasse and generates methane.
  • Effluent from the anaerobic digester is treated in a membrane bioreactor to remove additional organic matter.
  • Effluent from the membrane bioreactor is treated in a salt concentrator to separate a salt solution from the remaining effluent.
  • the salt solution contains mineral nutrients and may be used as a fertilizer.
  • the remaining effluent is well treated and may be re-used, for example for fermentation, irrigation, cooling tower make up water or boiler feed water.
  • the methane, or electricity generated from the methane may be sold as a product. Alternatively, the methane may be used to produce power for an associated distillery or for the vinasse treatment system.

  • the vinasse 18 leaves the distillation columns at about 90 degrees C.
  • the vinasse 18 passes through a heat exchanger to cool it before it enters the digester 12.
  • the vinasse 18 may be cooled to about 25 to 45 degrees C, or about 35 degrees C.
  • Vinasse 18 enters a covered tank of the digester 12 and is mixed with digestate in the digester 12.
  • the mixing may be intermittent, but is continuous in the sense that there is mixing throughout the digestion process.
  • the digester 12 is preferably a low rate digester.
  • the hydraulic residence time (HRT) of the digester 12 may be in a range of about 15 to 25 days, for example about 20 days. Enzymes may be added to the digester 12 to improve the digestion.

  • the CHP unit creates electricity and heat for use in the vinasse treatment system 10 or an associated distillery, or for sale to an electrical grid or local heating grid.
  • the digester 12 retains part of the solids in the vinasse 18 and accumulates biomass. Some of these solids are removed in a waste sludge 22 drawn from the digester 12.

Abstract

La présente invention concerne un système pour le traitement de vinasse qui combine un digesteur anaérobie (AD), un bioréacteur à membrane (MBR) et un concentrateur de sel tel qu'une unité d'électrodialyse (ED) ou d'osmose inverse (RO). L'AD consomme une partie de la matière organique dans la vinasse et génère du méthane. L'effluent de l'AD est traité dans le MBR pour éliminer la matière organique supplémentaire. L'effluent du MBR est traité dans le concentrateur de sel pour séparer une solution de sel de l'effluent résiduel. La solution de sel contient des nutriments minéraux et peut être utilisée en tant qu'engrais. L'effluent résiduel peut être réutilisé. Le méthane peut être commercialisé en tant que produit ou utilisé en tant que source d'énergie.
