    Abstract: The process for the production of alcohol and/or solvent from a biomass feedstock comprises the stages for pretreatment (P) of the biomass feedstock, for enzymatic hydrolysis (H) of the pretreated substrate, and for fermenting the hydrolyzate (F).To reduce the size of the fermenters, at least a portion of the solid residue contained in the hydrolyzate is extracted (Ex1) in such a way as to obtain a stream of solid residue (9) comprising lignin and a hydrolyzate (8) that is low in solid residue. Then, the stream of solid residue is washed (L) with a liquid stream in such a way as to recover a sugar-enriched liquid stream (15). The sugar-enriched liquid stream (15) is recycled in the enzymatic hydrolysis stage (H) to be able to upgrade the sugars without providing dilution of the streams in the process.

    Abstract: The present invention relates to a process for producing alcohols comprising:



    a. an IBE-type fermentation step in at least one bioreactor (R1) in the presence of a natural strain microorganism, and fed at least with an aqueous solution (1) of C5 and/or C6 sugars and a recycled acetone stream (3), in order to produce fermentation gases and a fermentation broth containing fermentation products;
    b. a step of recovering the fermentation products, in order to obtain a stream of fermentation products (2);
    c. a step of treating the stream of fermentation products comprising an acetone separation section in order to produce at least an acetone effluent (3) and an aqueous alcohol effluent (4);
    d. a step for recycling at least a fraction of the acetone effluent (3) from step c) to step a).

    Abstract: The process for the production of alcohol and/or solvent from a biomass feedstock comprises the stages for pretreatment (P) of the biomass feedstock, for enzymatic hydrolysis (H1 and HF), and for fermenting the hydrolyzate (HF). To prevent solids from being sent and to facilitate operating the section for purifying the fermentation products, at least a portion of the solid material in the fermentation wine is extracted (Ex1) to obtain a stream of solid residue (11) comprising lignin and a fermentation wine (12) that is low in solid material. Then, the stream of solid residue is washed (L) with a liquid stream to recover a liquid stream that is enriched with fermentation products (16). The liquid stream that is enriched with fermentation products (16) is recycled in the enzymatic hydrolysis stage (H1) to recover any fermentation product and to increase the overall yield of the process.

    Abstract: The invention relates to a process for extracting alcohols from an initial mixture (1) comprising alcohols in aqueous phase, with:



    a distillative separation by an isopropanol-butanol distillation column (III) equipped at the top with a condenser (c3), intended for separating said mixture into a water-isopropanol azeotrope stream (6) at the top and into a water-butanol azeotrope stream (7) at the bottom,
    a distillative separation intended for separating the water-butanol azeotrope stream into water and butanol, by a hetero-azeotropic distillation system comprising at least one water-recovering water column (IV) and at least one butanol (9)-recovering butanol column (V) equipped with a reboiler (r5),

    such that a heat transfer is performed from the top water-isopropanol azeotrope stream (6) entering the condenser of the isopropanol-butanol distillation column (III), to the stream entering the reboiler of the butanol column (V).
