Abstract
Un proceso de deshidrogenación de múltiples etapas que incluye poner en contacto, en una primera etapa, una corriente de alimentación que comprende un hidrocarburo y vapor con un catalizador de deshidrogenación bajo condiciones de deshidrogenación para producir un efluente de primera etapa, calentar el efluente de primera etapa, y poner en contacto, en una segunda etapa, el efluente de primera etapa calentado con un catalizador de deshidrogenación bajo condiciones de deshidrogenación para producir un efluente de segunda etapa que comprende un producto de deshidrogenación, en donde la primera etapa incluye un primer reactor y un segundo reactor arreglados en paralelo, y en donde la segunda etapa incluye un tercer reactor conectado en serie con el primer reactor y el segundo reactor. También se proporciona un sistema de deshidrogenación de múltiples etapas para llevar a cabo la deshidrogenación.
