Abstract

Un proceso para producir gas de síntesis de amoniaco a partir del reformado de hidrocarburos con vapor de agua en un reformador primario (1) equipado con una pluralidad de tubos catalíticos calentados externamente, y luego junto con aire en un reformador secundario (2), está caracterizado porque la reaccion de dichos hidrocarburos con dicho vapor de agua en dicho reformador primario (1) es llevada a cabo a una presion operativa de más de 35 bar en ps tubos catalíticos, porque el aire es agregado a dicho reformador secundario en exceso respecto de la cantidad de nitrogeno requerida para la síntesis de amoníaco, y porque el exceso de nitrogeno es eliminado corriente abajo del reformador secundario preferiblemente mediante separacion criogénica o mediante tamices moleculares del tipo TSA o PSA. Este proceso permite obtener elevadas capacidades de produccion de gas de síntesis y costos de inversion y de energía inferiores.
