摘要

Comprising 3 sections: a) a reaction that includes: a) the first stage of the Reaction, where Reagents are Oil and / or Fat Virgin and / or reused, Alcohol and Catalyst, and Fatty acid ester and glycerol; b) separating the dense Phase obtained in (a),High Content of GLYCERIN and Water; (c) new phase where the Initial Reaction Reagents are Oil and / or Fat Virgin and / or reused, Alcohol and dense Phase (b), (e) and (g); (d) separating the dense Phase obtained in (c), High Glycerine content; (E) where the second stage Reaction Reagents are phases of Light (a) and (c)Alcohol and Catalyst; (f) to separate dense Phase obtained in (e), High Content of GLYCERIN and Water; (g) to remove residual Catalyst content in the Light Phase (e) through contact with the dense Phase (c); (H) To Neutralize the waste flows of dense Phase; and (I) evaporate The excess of alcohol, in particular the separate Stream (d)A Highly Concentrated Product Glycerine; (b) includes a purification that Neutralize the residual from the biodiesel (f) or (g) (a), adding Water acidulated or PureAlcoholic solution of acid or evaporate the alcohol; Distillation; separate the resulting dense Phase; Wash with pure water or in counter current neutralized to remove all contaminants and remove Wax and other substances separable by Cooling; and (c) a Recovery of the Other Alcoholic Beverages, glycerol and Fatty Acids
