A process of Brewery effluent Treatment with ethanol production of Beer Vinegar, vinegar, Alcohol and Yeast Biomass

摘要

Integrated process for the treatment of liquid effluents and semisolid Breweries with simultaneous production of by-products with added value.Claim 1: a process of Brewery effluent treatment, characterized in that it comprises at least the following steps: a) separate the solids in the effluent Stream 1, (b) recover the filtering step in the current 3 (a), (c) separating the filtrate in two streams, Corrie Nte 4 and 8 (d) current, Distill the current 4Obtaining a Light fraction and a heavy fraction of vapour flows 9 and 19), and condensing the Vapors of the distillation product of Step (d), obtaining a current 5 Condensed, f) to divide the flow into two parts 5, 6 and 7 current Flow, Distill the current 7 (g) Getting a heavy fraction in the current 20 and a Light fraction in the current 18(H) to retrieve the current i flows 18, 8 and 9) filter, obtaining a fraction Concentrated solids in the flow Stream and Filtering in the 11 10, j) Feed the current 10 a reactor acidification of submerged cultivation, k) feed flows 12 and 13 to a reactor Acidification of submerged cultivation,(L) to adjust the concentration of ethanol in the submerged cultivation of acidification reactor by addition of the Reactor current 6 to 14 m), restore power to the output of said reactor acidification of submerged cultivation, the current 14 n) filter, obtaining a current filtrad And a current 15 or concentrated SolidsOr adjust the acidity of the filtering STEP (n) with sterile water in the current 16, obtaining a current from the current 17, p) (q) feed flows, 17, 19, 20, 21, 22 and 23 to a reactor of Yeast production of submerged cultivation, r) filter the current 24 output of Di Cho reactor Yeast production in Submerged culture.Obtaining a filtered stream flow concentrated in 26 and 25 S) flows Dry Yeast, 25, 2 and 11 in a spray drier, T) to recover the dry biomass resulting from step (S).
