Abstract

PROCEDIMIENTO PARA LA CONCENTRACION DE DISOLUCIONES O PRECONCENTRADOS ACUOSOS DE BIOPOLIMEROS ALTAMENTE PSEUDOPLASTICOS, CON UNA VISCOSIDAD MINIMA APARENTE DE 3.000 CPS. CONSISTE EN SOMETER LA DISOLUCION O EL PRECONCENTRADO, MANTENIDOS A UNA TEMPERATURA COMPRENDIDA ENTRE 25 C Y 50 C, A UNA ULTRAFILTRACION A TRAVES DE MEMBRANA, A UNA VELOCIDAD DE FLUJO LINEAL MINIMA DE 40 CM/SEG, EJERCIENDO UNA DIFERENCIA DE PRESION MEDIA A TRAVES DE LA MEMBRANA DE, AL MENOS, 2,0 ATM. TIENE APLICACIONES PARA LA CONCENTRACION DE COLOIDES HIDROFILOS PRODUCIDOS POR ~AXANTHOMONAS~B, QUE SE EMPLEAN EN EL DESPLAZAMIENTO DEL PETROLEO DE YACIMIENTOS PARCIALMENTE AGOTADOS Y EN LA INDUSTRIA ALIMENTARIA.
