Abstract

LA PRESENTE INVENCIÓN SE REFIERE A UN MÉTODO PARA PRODUCIR ETILENO RECOLECTANDO POR SEPARADO ETANO Y ETILENO, QUE SON SUBPRODUCTOS DE UN PROCESO DE PREPARACIÓN DE PROPILENO UTILIZANDO UNA REACCIÓN DE DESHIDROGENACIÓN DE PROPANO Y TAMBIÉN COMBINANDO UN PROCESO DE PREPARACIÓN DE PROPILENO EXISTENTE CON UN PROCESO DE CONVERSIÓN DE ETANO EN ETILENO. SEGÚN LA PRESENTE INVENCIÓN, EL ETILENO VALIOSO PUEDE SER PRODUCIDO MEDIANTE LA CONVERSIÓN DE LA MAYOR PARTE DE ETANO Y ETILENO, ES DECIR, SUBPRODUCTOS DE UN PROCESO DE DESHIDROGENACIÓN DE PROPANO, EN ETILENO SIN UTILIZAR EL ETANO COMO COMBUSTIBLE, MEJORANDO ASÍ LA EFICIENCIA ECONÓMICA DEL PROCESO. ADEMÁS, UNA LÍNEA DE PRODUCTOS EN EL PROCESO DE REACCIÓN DE DESHIDROGENACIÓN DE PROPANO PUEDE CAMBIARSE DESDE UN PRODUCTO DE PROPILENO SOLO A DOS PRODUCTOS, ES DECIR, PROPILENO Y ETILENO, Y ASÍ LAS CONDICIONES OPERATIVAS DE UN REACTOR DE DESHIDROGENACIÓN DE PROPILENO Y LAS CONDICIONES OPERATIVAS DE UN DES-ETANIZADOR SE PUEDEN AJUSTAR DE ACUERDO CON LA SITUACIÓN DEL MERCADO, AUMENTANDO ASÍ LA PROPORCIÓN DE LA PRODUCCIÓN DE UNA LÍNEA DE PRODUCTOS FAVORABLES.
