Abstract
LAS MEJORAS EN LA PATENTE DE INVENCION N.G 534.726 POR PROCEDIMIENTO DE OBTENCION DE NITRATO POTASICO A PARTIR DE CLORURO POTASICO Y ACIDO NITRICO SEGUN LA INVENCION CONSISTE EN QUE INICIALMENTE, SE REALIZA UNA ETAPA DE REACCION EN LA QUE SE PONE EN CONTACTO EL CLORURO POTASICO CON UNA SOLUCION DE ACIDO NITRICO DILUIDO PROVINIENTE DE UNA ETAPA DE RECUPERACION DEL ACIDO POR REEXTRACCION Y CON UNA SOLUCION DE ACIDO NITRICO CONCENTRADO, DISOLVIENDO ASI TODO EL CLORURO POTASICO ALIMENTADO Y EVITANDO CRISTALIZACION ALGUNA DEL NITRATO POTASICO FORMADO PARA, POSTERIORMENTE, REALIZAR UNA ETAPA DE SEPARACION DE LAS IMPUREZAS INSOLUBLES QUE ACOMPAÑAN AL CLORURO POTASICO DE LA MEZCLA DE REACCION OBTENIDA DEJANDO ESTA TOTALMENTE CLARIFICADA Y EXENTA DE SOLIDOS. CON ESTAS MEJORAS PUEDE REALIZARSE INMEDIATAMENTE DESPUES DE LA ETAPA DE REACCION UNA COMPLETA SEPARACION DE LAS IMPUREZAS INSOLUBLES DEL CLORURO POTASICO, ELIMINANDOSE POR COMPLETO LOS PROBLEMAS QUE ESTAS ORIGINAN Y CONDUCIENDO A UN NITRATO POTASICO BLANCO DE ELEVADA PUREZA APTO PARA CUALQUIER USO.
