Abstract

Tubos de intercambio de calor con salientes en los que la relación dimensional de las salientes es menor de 5, proporcionan mayor intercambio de calor indirecto que los tubos de intercambio de calor convencionales con, o sin aletas, cuando son utilizados en una suspensión que comprende una fase líquida, en la que están dispersas burbujas de gas que fluyen o sólidos en partículas y burbujas de gas que fluyen. Las salientes, y típicamente también los ejes geométricos longitudinales de los tubos de intercambio de calor, están alineados en una dirección paralela a, o en una espiral a lo largo de la dirección de flujo de burbujas. Esto es útil para aumentar (i) la productividad de un reactor de síntesis de hidrocarburos de Fischer - Tropsch de suspensión sin aumentar la temperatura en el reactor o (ii) aumentando la producción de hidrocarburos de más alto peso molecular reduciendo la temperatura de reacción a una conversión de alimentación dada. Reivindicación 1: Un procedimiento para agregar o remover calor a, o de una suspensión que comprende una fase líquida y por lo menos una de (i) burbujas de gas que fluyen e (ii) burbujas de gas que fluyen y sólidos en partículas, por intercambio indirecto de calor con elementos ubicados en la suspensión, en el que dichos elementos comprenden uno o más conductos huecos que contienen un fluido de intercambio de calor que fluye dentro de los mismos, en relación de intercambio de calor indirecto con dicha suspensión circundante, teniendo cada uno de dicho uno o más conductos una pluralidad de salientes vinculados a, y dispuestos hacia fuera de su superficie exterior, y alineados longitudinalmente o en espiral a lo largo de la dirección de flujo de dichas burbujas de gas, y en el que dichas salientes tienen una proporción dimensional de menos de cinco.
