Abstract

PROCEDIMIENTO PARA LA OBTENCION DE AMONIACO A PARTIR DE GAS DE SINTESIS OBTENIDO POR REFORMADO DE HIDROCARBUROS CON VAPOR Y OXIGENO. CONSISTE EN LA GENERALCION DE GAS DE SITESIS POR REFORMADO PRIMARIO DE LOS HIDROCARBUROS CON VAPOR Y POR REFORMADO SECUNDARIO DE LA MEZCLA GASEOSA RESULTANTE CON OXIGENO, SOMETIENDOSE UNA PARTE DE HIDROCARBURO DE PARTIDA MEZCLADO CON EL VAPOR A UN REFORMADO TERCIARIO EN EL QUE EL CALOR NECESARIO ES SUMINISTRADO A PARTIR DE LA MEZCLA PROCEDENTE DEL REFORMADO SECUNDARIO. EL GAS QUE SE ENVIA AL REACTOR DE SINTESIS SE SECA UTILIZANDO TAMICES MOLECULARES, QUE SE ENCUENTRAN ALTERNATIVAMENTE Y EN CADA CICLO DE OPERACION EN LAS ETAPAS DE REGENERACION, CALENTAMIENTO, ENFRIAMIENTO Y ADSORCION, RESPECTIVAMENTE. LA SINTESIS DEL AMONIACO TIENE LUGAR PREFERENTEMENTE A PRESION ENTRE 40 Y 80 KG/CM2. EL AMONIACO SE ABSORBE CON AGUA SOMETIENDOSE LA SOLUCION OBTENIDA A DESTILACION EN DOS COLUMNAS QUE OPERAN A PRESIONES DISTINTAS.
