Abstract

LA INVENCION SE REFIERE A UN METODO DE FABRICACION DE PASTA DE PAPEL A PARTIR DE UNA MATERIA PRIMA LIGNOCELULOSICA A BASE DE PLANTAS ANUALES O VIVACES O DE RESTOS DE ESTAS PLANTAS. EL METODO CONSISTE EN IMPREGNAR LA MENCIONADA MATERIA PRIMA CON UNA SOLUCION ACUOSA DE SOSA DE MODO QUE LA PROPORCION PONDERAL DE SOSA ESTE ESENCIALMENTE COMPRENDIDA ENTRE EL 3,5 % Y EL 10 % EN RELACION CON LA MATERIA SECA Y QUE LA TASA PONDERAL DE HIDRATACION DE LA MATERIA CELULOSICA DESPUES DE LA IMPREGNACION SEA AL MENOS IGUAL AL 40 %. A CONTINUACION SE SOMETE LA MATERIA LIGNOCELULOSICA ASI IMPREGNADA A UNA OPERACION DE CRAQUEO AL VAPOR QUE CONSISTE EN SOMETERLA A PRESION EN ATMOSFERA SATURADA DE VAPOR PARA A CONTINUACION ALIVIAR LA SOBREPRESION MUY BRUSCAMENTE POR MEDIO DE UNA VALVULA DE PASO DIRECTO. LA FRACCION SOLIDA QUE CONSTITUYE LA PASTA DE PAPEL SE SEPARA DE LA FASE ACUOSA Y DE LOS PRODUCTOS HIDROSOLUBLES. CON ESTE METODO SE OBTIENEN PASTAS DE PAPEL DE BUENA CALIDAD QUE DESTACAN EN PARTICULAR POR UNA LONGITUD DE ROTURA SUPERIOR A 5,500 METROS Y POR UNA TASA DE LIGNINA ELEVADA (CON UN INDICE KAPPA COMPRENDIDO ENTRE 60 Y 65).
