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 concerns a process for recovering fermentation products present in a fermentation mash produced in a bioreactor (9), comprising a step a) in which a gas stream (15) is sent into the fermentation mash under pressure in order to entrain at least a portion of the products and produce a gas stream (16) which is enriched in fermentation products. The process comprises a step h) for storage of the fermentation gases and the gas stream which is sent to the step a) is constituted by the stored fermentation gases.

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.
