Abstract

SE DESCRIBE UN PROCESO MEJORADO PARA LA PRODUCCION DE NITRITOS Y ANHIDRIDOS A PARTIR DE HIDROCARBUROS PO REACCION CON UN GAS OXIGENANTE FORMADO POR OXIGENO, AIRE, U OTRO GAS ENRIQUECIDO CON OXIGENO EN RELACION CON EL AIRE O AMONIACOCUADO EL PRODUCTO BUSCADO SEA NITRITO, EN PRESENCIA DE UN CATALIZADOR ADECUADO. DURANTE EL PROCESO, LA ADICION DE UN SEPARADOR SELECTIVO PERMITE RECICLAR UNA PARTE IMPORTANTE DEL HIDROCARBURO NO REACCIONADO, ASI COMO CONTROLAR LA CANTIDAD DE GAS NO INFLAMABLE PRESENTE EN LA MEZCLA. ESTE PROCESO ESTA CARACTERIZADO POR UNA GRAN SELECTIVIDAD EN LA FORMACION DEL PRODUCTO.
