Abstract

SE OBTIENE METIONINA CON UN METODO DE PRODUCCION MEJORADO A LA VEZ QUE SE REDUCE LA CARGA DE AGUA RESIDUAL ELIMINADA POR UN PROCESO QUE CONSTA DE LOS PASOS DE: A) ADICION DE UN COMPUESTO COMO MINIMO SELECCIONADO ENTRE CARBONATO POTASICO, BICARBONATO POTASICO E HIDROXIDO POTASICO A UNA SOLUCION QUE CONTIENE 5 - ( BE} METILMERCAPTOETIL)HIDANTOINA, B) SATURACION DE LA SOLUCION RESULTANTE CON DIOXIDO DE CARBONO EN FORMA DE GAS Y SEPARACION DE LA METIONINA DEPOSITADA OBTENIENDO UN PRIMER FILTRADO, C) TRANSFERENCIA DE PARTE O LA TOTALIDAD DEL PRIMER FILTRADO AL PASO D), D) CALENTAMIENTO DEL FILTRADO TRANSFERIDO, ADICION DE UN SOLVENTE HIDROSOLUBLE Y SATURACION CON DIOXIDO DE CARBONO EN FORMA DE GAS PARA DEPOSITAR METIONINA Y BICARBONATO POTASICO, CON SEPARACION DE ESTOS DEPOSITOS MIENTRAS SE OBTIENE UN SEGUNDO FILTRADO, Y E) DEVOLUCION DEL SEGUNDO FILTRADO AL PASO A) SI SE DESEA.
