Abstract
Un proceso continuo de desalinización de vinazas y obtención de sales de potasio que comprende los pasos de filtrar la vinaza proveniente de destilería de alcohol; hacer pasar dicha vinaza por columnas de intercambio iónico con resinas catiónicas del tipo ácido fuerte en estado H; obtener la vinaza desalinizada; regenerar con solución de ácido sulfúrico dichas columnas de intercambio; obtener una solución ácida de sulfato de potasio en una concentración de al menos 6% a partir de la regeneración; y cristalizar dicho sulfato de potasio.A continuous process of desalination of vinasses and obtaining of potassium salts comprising the steps of filtering the vinasse from alcohol distillery; passing said vinasse through ion exchange columns with cationic resins of the strong acid type in state H; get desalinated vinasse; regenerating said exchange columns with sulfuric acid solution; obtain an acidic solution of potassium sulfate in a concentration of at least 6% from regeneration; and crystallize said potassium sulfate.
