Abstract
UN PROCESO PARA LA REDUCCION SUSTANCIAL O ELIMINACION COMPLETA DEL SULFATO DE AMONIO GENERADO DURANTE LA PRODUCCION DE ACRILONITRILO POR LA OXIDACION AMONAL DIRECTA DE PROPILENO/PROPANO, EL AMONIACO Y UN GAS QUE CONTIENE OXIGENO (V.G., AIRE) SOBRE UN CATALIZADOR DE LECHO FLUIDO EN DONDE LA MEJORA COMPRENDE INTRODUCIR METANOL EN DICHO REACTOR EN LA PARTE SUPERIOR DEL MISMO EN UNA SITUACION DONDE EL METANOL REACCIONA CON AL MENOS UNA PARTE EXCEDENTE SUSTANCIAL DEL AMONIACO, SI NO CON TODA, SIN AFECTAR A LA PRODUCCION DE ACRILONITRILO. PREFERENTEMENTE, EL METANOL SE INTRODUCE DENTRO DEL REACTOR POR DEBAJO DE SU TEMPERATURA DE COQUEFACCION. EN PARTICULAR, CUANDO SE UTILIZA UN CATALIZADOR DE LECHO FLUIDO POBRE EN OXIGENO, SE INTRODUCE UN GAS QUE CONTIENE OXIGENO ADICIONAL EN EL REACTOR A UNA DISTANCIA ENTRE 8 Y 14 PULGADAS DE LA POSICION DE ALIMENTACION DEL METANOL.
