Abstract

Un método y un sistema para proveer calor a un proceso de conversion química que se emplea con ventaja en la produccion de olefinas por deshidrogenacion catalítica de un hidrocarburo correspondiente. El proceso de deshidrogenacion catalítica emplea vapor como diluyente operando con una proporcion de vapor a aceite que puede ser de 1,0 o menor y una temperatura relativamente baja en la caldera del sobrecalentador de vapor. El proceso y el sistema se emplean con ventaja para la produccion de estireno por deshidrogenacion catalítica de etilbenceno. Reivindicacion 1: Un método para proveer calor a una corriente de un proceso de conversion química que contiene por lo menos un producto químico reactivo, caracterizado porque comprende los pasos de: a) sobrecalentar un fluido de transferencia térmica; b) transferir calor desde el fluido de transferencia térmica sobrecalentado a una corriente de proceso; c) dividir por lo menos parte del fluido de transferencia térmica en una primera parte y una segunda parte; d) presurizar la primera parte del fluido de transferencia térmica; e) reciclar la primera parte presurizada del fluido de transferencia térmica al paso de sobrecalentamiento (a); y, f) introducir la segunda parte del fluido de transferencia térmica a la corriente de proceso. Reivindicacion 11: Un proceso para la produccion de olefinas por deshidrogenacion catalítica de un hidrocarburo, caracterizado porque comprende: a) sobrecalentar una corriente de alimentacion de vapor en un calentador que comprende una pluralidad de zonas de calentamiento; b) transferir calor desde el vapor sobrecalentado a una corriente de proceso que comprende vapor como diluyente y el hidrocarburo, donde el calor es suficiente para realizar la deshidrogenacion catalítica de por lo menos una parte del hidrocarburo en una zona de reaccion, donde luego de transferir el calor el vapor sobrecalentado se convierte en vapor agotado; c) dividir dicha corriente agotada en una primera parte y una segunda parte; d) presurizar la primera parte de dicho vapor agotado; e) reciclar la primera parte presurizada del vapor agotado a una primera zona de calentamiento en el calentador; f) reciclar la segunda parte a una seccion diferente del calentador hacia una segunda zona de calentamiento en el calentador; g) calentar la segunda parte del vapor agotado para regenerar el vapor sobrecalentado en la segunda zona de calentamiento; y h) combinar por lo menos una parte del vapor sobrecalentado con la corriente de proceso.
