Abstract

SE UTILIZAN ETILENAMINAS PARA LAVAR LA PASTA Y RETIRAR LA LIGNINA. UN PROCESO PARA LAVAR UNA MEZCLA DE PASTA DE CELULOSA QUE CONTIENE LIGNINA PARA RETIRAR AL MENOS UNA PORCION DE LA LIGNINA DE LA MISMA CONSTE EN EL USO DE UNA COMPOSICION DE LAVADO CON AL MENOS 100 PPM DE UNA ETILENAMINA. EL PROCESO SUPONE UNA MEJORA EN EL PROCESO DE LAVADO DE UNA MEZCLA DE PASTA DE CELULOSA QUE CONTIENE LIGNINA EN EL QUE SE UTILIZA UNA COMPOSICION DE LAVADO PARA RETIRAR AL MENOS UNA PORCION DE LA LIGNINA, Y LA MEJORA CONSISTE EN EL USO DE AL MENOS 100 PPM DE UNA ETILENAMINA CON LA COMPOSICION DE LAVADO Y/O EL USO DE UNA CANTIDAD DE ETILENAMINA EQUIVALENTE POR LO MENOS A 100 PPM EN BASE A LA COMPOSICION DE LAVADO CON LA COMPOSICION DE LAVADO. LA COMPOSICION DE LAVADO TAMBIEN ES NUEVA E INCLUYE UNA COMPOSICION DE LAVADO PARA EL LAVADO DE PASTA DE KRAFT QUE CONTIENE AGUA Y AL MENOS 100 PPM DE UNA ETILENAMINA.
