Abstract
Inventia se refera la industria vinicola si anume la un procedeu de denocivizare a slamului albastru rezultat la deferizarea vinurilor. Procedeul consta in aceea ca slamul albastru initial, tratat preliminar cu o solutie apoasa de HCl 15...20%, in raport masic de 0,2...0,3, in vederea aducerii sistemului format la un pH optim de 1,5...2,0 si destabilizarii starii lui microcoloidale, se filtreaza sau se centrifugheaza, rezultand o solutie acida fara ioni ferocian si un precipitat, care se trateaza cu var nestins pulbere, in raport masic de 0,05...0,15 si cu o solutie apoasa de hidrocarbonat de potasiu 25...30%, intr-un raport masic de 0,8...1,2, rezultand un sistem microdispers coloidal, care se matureaza la temperatura de 85...90oC la barbotare cu vapori de apa. Amestecul obtinut se centrifugheaza. Solutia formata, cu capacitatea de complexare de 102...103 mg FeIII/L, poate fi utilizata la deferizarea vinurilor, iar precipitatul alcalin se spala contra flux cu apa pentru inlaturarea urmelor de ferocian, se trateaza cu solutia acida rezultata de la prima tratare, formand un namol inactiv, care poate fi utilizat in agricultura, la tratarea diferitelor soluri. Eluatul format, dupa spalarea precipitatului alcalin, se reutilizeaza la prepararea solutiei de hidrocarbonat de potasiu. Rezultatul consta in denocivizarea slamului albastru cu recuperarea ferocianurii de potasiu (K4[FeII(CN)6] ? 3H2O), sub forma de solutie apoasa concentrata. ŕThe invention relates to the wine industry, namely to a process of denocivization of the blue slime resulting in the deferment of wines. The process consists in that the initial blue slurry, preliminary treated with an aqueous solution of 15 ... 20% HCl, with a mass ratio of 0.2 ... 0.3, in order to bring the formed system to an optimum pH of 1, 5 ... 2.0 and destabilizing its microcolloid state, is filtered or centrifuged, resulting in an acid solution without ferocian ions and a precipitate, which is treated with lime powder, in a mass ratio of 0.05 ... 0, 15 and with an aqueous solution of potassium hydrocarbonate 25 ... 30%, in a mass ratio of 0.8 ... 1.2, resulting in a colloidal microdisperse system, which matures at 85 ... 90 ° C. when bubbling with water vapor. The mixture obtained is centrifuged. The solution formed, with the complexation capacity of 102 ... 103 mg FeIII / L, can be used in the deferment of wines, and the alkaline precipitate is washed against flow with water to remove the traces of ferocian, it is treated with the acid solution resulting from the first treatment. , forming an inactive sludge, which can be used in agriculture, to treat different soils. The eluate formed, after washing the alkaline precipitate, is reused in the preparation of the potassium hydrocarbon solution. The result is the decoction of the blue sludge with the recovery of potassium ferrocyanide (K4 [FeII (CN) 6]? 3H2O), as a concentrated aqueous solution. à
