Abrégé français

Un procédé qui consiste à clarifier une vinasse dans un processeur mécanique pour produire un flux de solides fins en suspension et une vinasse clarifiée. Le procédé consiste en plus à amener la vinasse et la vinasse clarifiée, séparément ou dans un flux combiné, à un ou plusieurs évaporateurs afin de produire un ou plusieurs flux à teneur réduite de solides en suspension, chaque flux ayant une quantité réduite de solides en suspension et une viscosité inférieure à celle de flux de procédés ayant une teneur en solides totale comparable, mais une plus grande quantité de solides en suspension. Le procédé peut de plus consister à effectuer un traitement supplémentaire d'un ou de plusieurs des flux à teneur réduite de solides en suspension afin de produire de la biohuile.


Abrégé anglais

A method that includes clarifying a thin stillage product in a mechanical processor to produce a fine suspended solids stream and a clarified thin stillage is provided. The method further includes providing the thin stillage product and the clarified thin stillage, separately or in a combined stream, to one or more evaporators to produce one or more reduced suspended solids streams, each stream having a reduced amount of suspended solids and a lower viscosity as compared to process streams having a comparable total solids content but containing a higher amount of suspended solids. The method can further included further processing of one or more of the reduced suspended solids streams to produce a bio-oil product.

separately or in a
combined stream, to one or more evaporators to produce at least two reduced
suspended
