Abstract

PROCEDIMIENTO PARA AUMENTAR LA VELOCIDAD DE FILTRACION DE UNA SUSPENSION LIQUIDA DE CARBON. SE DISUELVE EL COPOLIMERO DE ETILENO-ACETATO DE VINILO EN UN ACEITE LIGERO PARA REDUCIR SU VISCOSIDAD. SE HACE PASAR A TRAVES DE LA TORTA DE PRE-REVESTIMIENTO DE COADYUVANTE DE FILTRACION ANTES DE LA FILTRACION DE LA SUSPENSION DE CARBON A TRAVES DE ELLA; O BIEN SE AÑADE DIRECTAMENTE A LA SUSPENSION DE CARBON UNA CANTIDAD DEL POLIMERO ENTRE 0,01 Y 2 POR 100 EN PESO; O BIEN SE EFECTUAN LOS DOS TRATAMIENTOS CONJUNTAMENTE. OPCIONALMENTE PUEDE AÑADIRSE A LA SUSPENSION DE CARBON JUNTO AL POLIMERO UN ALCOHOL ALIFATICO HASTA DE DIEZ CARBONOS, DE 0,05 A 15 POR 100 EN PESO.
