Abstract

PROCESO MEJORADO PARA LA PRODUCCION DE NITRILOS Y OXIDOS DE HIDROCARBUROS MEDIANTE REACCION CON OXIGENO, AIRE O UN GAS ENRIQUECIDO EN OXIGENO EN RELACION CON AIRE, PREFERIBLEMENTE EL ULTIMO, Y AMONIACO, EN DONDE SE PREFIERE UN NITRILO, CON PRESENCIA DE UN CATALIZADOR ADECUADO. UN ALCANO (POR EJEMPLO, PROPANO) SE CONVIERTE EN ALQUENO EN UN DESHIDROGENADOR CATALITICO. EL CHORRO DEL PRODUCTO SE INTRODUCE EN UN REACTOR DE AMOXIDACION/OXIDACION. EL PRODUCTO ALLI FORMADO SE RECUPERA EN UNA TORRE CONVENCIONAL DE ENFRIAMIENTO, CUYA EMANACION GASEOSA ES TRATADA EN UN SEPARADOR A FIN DE OBTENER UN CHORRO DE ALCANO/ALQUENO ("EL PRIMER CHORRO"), UN CHORRO DE DESHECHO ("EL SEGUNDO CHORRO"), UN CHORRO DE OXIGENO ("EL TERCER CHORRO") SI ASI SE DESEA, Y UN CHORRO DE HIDROGENO ("EL CUARTO CHORRO"). EL CHORRO DE OXIGENO PUEDE RECICLARSE EN EL REACTOR DE AMOXIDACION/OXIDACION SEGUN SU CONTENIDO EN NITROGENO. EL PRIMER CHORRO MAS AL MENOS UNA PARTE DEL CUARTO SE INTRODUCE EN UNA UNIDAD DE OXIDACION SELECTIVA A FIN DE ELIMINAR EL OXIGENO RESTANTE Y SE RECICLA EN EL DESHIDROGENADOR. EL RESIDUO DEL CHORRO DE HIDROGENO, SI ES QUE EXISTE, PUEDE TOMARSE COMO PRODUCTO O VENTILARSE. EL DESHIDROGENADOR PUEDE SER MULTIGRADUAL PARA ASI PODER EXTRAER EL CHORRO DEL PRODUCTO DE UN REACTOR QUE NO SEA EL PRIMERO O EL ULTIMO, INTRODUCIR LOS CHORROS DE RECICLAJE EN EL SIGUIENTE REACTOR SECUENCIAL E INTRODUCIR LA EMANACION DEL ULTIMO REACTOR EN EL PRIMERO, EN UN REACTOR QUE TENGA UNA COMPOSICION SIMILAR DE ALQUENO O DIRECTAMENTE EN EL REACTOR DE AMOXIDACION/OXIDACION.
