Abstract

Esta invención utiliza una primera etapa o etapa de preparación, para separar la mayor parte de la humedad, y una segunda etapa o etapa de acabado, para completar el secado. La primera etapa puede utilizar un área de membrana relativamente pequeña y un gas de purga de calidad relativamente baja, mientras que la segunda etapa puede utilizar un área de membrana grande y un gas de purga de alta calidad, tal como alguna purga de regreso de producto.
