Abstract
SE TRATA DE UN GAS AGRIO QUE CONTIENE AMONIO AL QUE SE LE REALIZA LA COMBUSTION A UNA ALTA TEMPERATURA DE LLAMA CON UNA PUREZA DE OXIGENO DE AL MENOS EL 90 POR CIENTO EN UN COMBUSTOR ENFRIADO EXTERNAMENTE. A CONTINUACION, EL PRODUCTO LIBRE DE AMONIO SE ENFRIA JUNTO CON UN GAS ACIDO ADICIONAL QUE NO CONTIENE AMONIO, SE PASA A UN HORNO CLAUS DONDE AL MENOS A UN TERCIO DEL SULFURO DE HIDROGENO SE LE REALIZA LA COMBUSTION CON AIRE ENRIQUECIDO EN OXIGENO, PERMITIENDO ASI EL AUMENTO DE LA RECUPERACION DEL AZUFRE EN UNA PLANTA CLAUS SIN EFECTOS PERJUDICIALES SOBRE LA VIDA DEL CATALIZADOR, LOS REFRACTORIOS DE HORNO Y LAS GOTAS DE PRESION.
