Abstract

PROCEDIMIENTO PARA FLOCULAR SUSPENSIONES ACUOSAS Y ANALOGAS. COMPRENDE: A) INCORPORAR EN UNA SOLUCION ACUOSA UNA CANTIDAD ESTABILIZADORA DE FLOCO, PARA FLOCULAR LA SUSPENSION; B) CIZALLAR A LOS SOLIDOS FLOCULADOS EN UN MEDIO ACUOSO, PARA REDUCIR SU TAMAÑO; C) SEPARAR LOS SOLIDOS FLOCULADOS DEL MEDIO ACUOSO MEDIANTE DESAGUADO EN UNA CENTRIFUGADORA. LOS SOLIDOS FLOCULADOS SON PARTICULAS DE CATALIZADOR DE COBRE; EL MEDIO ACUOSO ES UN MEDIO DE REACCION DE HIDROLISIS DE ACRILONITRILO Y EL ESTABILIZANTE DE FLOCO ES UN MATERIAL POLIMERICO SINTETICO, QUE TIENE UNA VISCOSIDAD SUPERIOR A 10 (MEDIDA EN UN VISCOSIMETRO DE CAPACIDAD A 34GC EN UNA DISOLUCION AL 0,5 POR CIENTO DE AGUA DESIONIZADA), CONTIENE PARTICULAS POLIMERICAS CON UN TAMAÑO < 10 MUM, Y SE ELIGE ENTRE COPOLIMERO DE ACRILAMIDA Y MONOMEROS CATIONICOS Y MONOMEROS ANIONICOS. SE UTILIZAN EN EL SECTOR PAPELERO Y VERTIDOS RESIDUALES.
