Abstract

Procedimiento para la síntesis de amoniaco. En donde se hacen reaccionar hidrógeno y nitrógeno a presión elevada en un convertidor de síntesis de amoniaco, para producir amoniaco, caracterizado porque comprende: recuperar el amoniaco del convertidor de síntesis de amoniaco por absorción con agua, para formar una mezcla de agua-amoniaco. Destilar la mezcla de agua-amoniaco en una columna de destilación para recuperar amoniaco anhídrido; vaporizador el amoniaco en etapas a presión reducida, con lo cual se forma en cada etapa vapor y el amoniaco líquido se enfría: absorber dicho vapor con agua para formar una mezcla acuosa-amoniacal; y destilar dicha mezcla acuosa-amoniacal en la misma columna de destilación que dicha mezcla en agua-amoniaco.
