Abstract:
A process for obtaining a polymeric complex from a by-product effluent obtained in a process for manufacturing alcohol by distilling a fermented aqueous sugar solution containing yeast, comprising the steps of:obtaining the effluent comprising a fermented sugar solution containing yeast after distilling alcohol therefrom;adding to said effluent a flocculant selected from the group consisting of chemical flocculants, biological flocculants and mixtures thereof, and forming a homogeneous mixture of said flocculant and said effluent;heating said homogeneous mixture to a temperature of at least about 80.degree. C.;removing yeast from the heated mixture by a first decantation;mixing the heated mixture from which yeast has been removed, and removing therefrom insoluble solids and muds by a second decantation; andconcentrating the mixture after said second decantation by partially evaporating water therefrom to obtain an aqueous solution of the polymeric complex.
