Abstract

Se proporciona aquí un sistema de purga de despresurización unidireccional para un reactor tubular de alta presión con un hiper que minimiza la temperatura de metal pared de tubo durante un evento de descomposición en donde el sistema evita que las paredes de reactor alcancen una temperatura con capacidad de provocar que el metal de tubo se austenice. También se proporcionan métodos para diseñar, y métodos de operación de, un sistema de purga de despresurización unidireccional.
