Abstract

SE PRODUCEN NITRITOS Y OXIDOS A PARTIR DE HIDROCARBUROS POR REACCION CON O2, AIRE O PREFERIBLEMENTE AIRE ENRIQUECIDO CON O2 Y NH3 CUANDO SE DESEA NITRITO, EN PRESENCIA DE UN CATALIZADOR ADECUADO. UN ALCANO, COMO EL PROPANO SE CONVIERTE EN ALQUENO EN UN DESHIDROGENADOR. LA CORRIENTE DE PRODUCTO SE INTRODUCE EN UN REACTOR DE AMOXIDACION/OXIDACION. EL PRODUCTO FORMADO EN EL SE RECUPERA EN UNA TORRE DE EXTINCION CONVENCIONAL. EL EFLUENTE GASEOSO DE ESTA TORRE SE TRATA EN UNA UNIDAD PSA PARA FORMAR UNA CORRIENTE GASEOSA QUE CONTIENE ALCANO SIN REACCIONAR, ALQUENO Y UNA CANTIDAD PEQUEÑA DE O2 Y N2. EL GAS QUE PUEDE CONTENER H2 SE INTRODUCE EN UNA UNIDAD DE OXIDACION SELECTIVA PARA SEPARAR EL O2 REMANENTE Y DESPUES SE RECICLA AL DESHIDROGENADOR. LA INVENCION INCLUYE DATOS SOBRE EL SISTEMA PSA, ADSORBENTES Y CONDICIONES DEL PROCESO.
