Abstract
Producción de monóxido de carbono e hidrógeno a partir de una mezcla gaseosa que también contiene metano. El proceso está simplificado y el número de elementos del equipo reducido, mientras que se mantiene un alto rendimiento y pureza de hidrógeno. Hay menos columnas de separación y se han eliminado la columna lavadora y la columna de destilación para separar el monóxido de carbono y el metano. La instalación para este procedimiento solo requiere dos columnas lavadoras y dos separadores de fase. La mezcla se refrigera, se condensa parcialmente y se envía a un separador de fases (A). El condensado va a una columna lavadora (B) para proporcionar hidrógeno gaseoso (H{sub,2}) por cabeza y un líquido que contiene metano y monóxido de carbono (CO) por cola. El gas se condensa parcialmente en un cambiador de calor (K) y se separa en un separador e fases (H) en H{sub,2} y un condensado. El condensado se envía a un columna lavadora (I) dando un H{sub,2} gaseoso rico por cabeza y un COlíquido rico por cola. El gas se calienta y se recicla a la mezcla para ser tratado. La fracción líquida de la primera columna puede enviarse a una columna de purificación (C) para producir monóxido de carbono puro por cabeza y un líquido rico en metano por cola. El gas de la primera columna y del primer separador se envían a una unidad de permeación o adsorción o se recicla al principio del proceso. La energía de separación se suministra mediante una expansión de Joule Thomson de la mezcla existente o mediante intercambio de calor con un líquido criogénico o mediante inyección de un líquido criogénico en una de las columnas.
