Abstract

Un procedimiento para la producción de caprolactama, que comprende: (a) hacer reaccionar aire con amoniaco gas en una zona de conversión de amoniaco para producir óxido nítrico; (b) oxidar una porción del óxido nítrico a dióxido de nitrógeno para producir una corriente de gas de proceso rica en NOx; (c) hacer reaccionar la corriente rica en NOx con carbonato amónico en una zona de formación de nitrito para producir nitrito amónico, manteniéndose una relación NO/NO2 sustancialmente equimolar en la corriente de gas de proceso rica en NOx en la zona de formación de nitrito; (d) reducir el nitrito amónico a sulfato diamónico de hidroxilamina; (e) hidrolizar el sulfato diamónico de hidroxilamina a sulfato de hidroxilamina; (f) oximar el sulfato de hidroxilamina con ciclohexanona para producir ciclohexanonaoxima; y (g) convertir la ciclohexanonaoxima en caprolactama, caracterizado por añadir oxígeno suplementario en una corriente gaseosa que contiene más de aproximadamente 50% en volumen de oxígeno, aguas abajo de la zona de conversión de amoniaco, en la zona de formación de nitrito, para aumentar la cantidad y la velocidad de formación de dióxido de nitrógeno en la corriente de gas de proceso rica en NOx.
