Abstract

Una planta de sintesis (200) incluye un sistema de separacion corriente arriba de un ciclo de sintesis que remueve el nitrogeno en exceso y otros compuestos gaseosos de un gas de alimentacion que tiene una proporcion de hidrogeno a nitrogeno menor de 3:1, con lo cual se produce un singas con una proporcion de hidrogeno a nitrogeno de aproximadamente 3.1. Los sistemas de separacion particularmente preferidos incluyen una caja fria (270) con un refrigerante diferente del aire, o un sistema de absorcion por oscilacion de presion.
