Abstract

EL SUMINISTRO DE AIRE A UN SISTEMA PREPURIFICADOR DE ADSORCION/SISTEMA DE SEPARACION DE AIRE CRIOGENICO PARA LA PRODUCCION DE NITROGENO Y/O OXIGENO SECOS, DE ALTA PUREZA, ES SECADO EN UN SECADOR DE MEMBRANA CARACTERIZADO PREFERIBLEMENTE POR UNA VIA DE FLUJO A CONTRACORRIENTE. EL SECADO SE AUMENTA POR EL USO DE GAS DE PURGA EN EL LADO PERMEADO DEL SECADOR DE MEMBRANA, CON EL GAS PRODUCIDO O DE DESECHO DE UN SISTEMA DE ADSORCION O UN SISTEMA DE SEPARACION DE AIRE CRIOGENICO, SE HAN UTILIZADO EL GAS DE SUMINISTRO SECADO O EL AIRE AMBIENTAL COMO GAS DE PURGA. SE EMPLEAN DOS MATERIALES DE MEMBRANA EN EL SECADOR DE MEMBRANA, EN ETAPA UNICA O EN DOS ETAPAS, PARA LA ELIMINACION AUMENTADA DE AGUA Y DIOXIDO DE CARBONO DEL AIRE SUMINISTRADO.
