Abstract

PROCEDIMIENTO PARA LA GENERACION DE AZUFRE ELEMENTAL A PARTIR DE UN GAS QUE CONTENGA ACIDO SULFHIDRICO. EL GAS A TRATAR, QUE CONTIENE H2S Y COMPUESTOS CARBONADOS, LLEGA PRIMERO A LA CAMARA DE COMBUSTION (2) DE UNA INSTALACION CLAUS, DE LA QUE SE EXTRAE UNA MEZCLA DE GASES CON 1 A 3 MOLES DE H2S POR CADA MOL DE SO2. EN AL MENOS UNA ETAPA CLAUS (9) SE TRANSFORMA LA MEZCLA DE GASES PARCIALMENTE EN AZUFRE ELEMENTAL A UNAS TEMPERATURAS SUPERIORES AL PUNTO DE ROCIO DEL AZUFRE, CONDENSANDOSE Y SEPARANDOSE EL AZUFRE ELEMENTAL EN UN REFRIGERADOR DE AZUFRE (11). DEL ULTIMO REFRIGERADOR DE AZUFRE (11) DE LA INSTALACION CLAUS SE EXTRAE UN GAS DE ESCAPE (15) QUE CONTIENE DE 0,5 A 2% EN VOLUMEN DE H2S ASI COMO COS, CS2 Y H2O. A ESTE GAS DE ESCAPE SE LA AGREGA OXIGENO (16), SE CALIENTA A UNA TEMPERATURA DE 200 (GRADOS) C COMO MINIMO Y SE CONDUCE HASTA UN CATALIZADOR (20) QUE CONSTA AL MENOS DE UN 80% EN PESO DE TIO2. EL AZUFRE ELEMENTAL AQUI FORMADO ES CONDENSADO Y SEPARADO (24). DESPUES, EL GAS SE DIRIGEHACIA EL CATALIZADOR (28) COMPUESTO AL MENOS DE UN 80% EN PESO DE AL2O3 A TEMPERATURAS ENTRE 120 Y 160 (GRADOS) C.
