Abstract

SE REFIERE A UN PROCESO PARA MEZCLAR DOS GASES DE DIFERENTES TEMPERATURAS Y/O COMPOSICIONES EN UN CONVERTIDOR PARA PRODUCIR SO3 A PARTIR DE UN GAS QUE TIENE SO2, CARACTERIZADO PORQUE: A) UN PRIMER FLUJO DE GAS QUE CONTIENE SO2 ES INTRODUCIDO EN EL CONVERTIDOR A TRAVES DE UNA TUBERIA DE SUMINISTRO CENTRAL Y PASADO A TRAVES DE UN INTERCAMBIADOR DE CALOR INTEGRADO, DICHO PRIMER FLUJO DE GAS CONTIENE MAS DE UN 13% EN VOLUMEN DE SO2; B) EL SEGUNDO FLUJO DE GAS ES SUMISTRADO VIA UN CONDUCTO DE ANILLO COLOCADO EN EL CONVERTIDOR DIRECTAMENTE ANTES O DESPUES DEL INTERCAMBIADOR DE CALOR INTEGRADO, DESDE EL CUAL EL SEGUNDO FLUJO DE GAS ES DESCARGADO A TRAVES DE UNA PLURALIDAD DE ABERTURAS Y ES ALIMENTADO DENTRO DEL PRIMER FLUJO DE GAS, DE TAL FORMA QUE SE MEZCLE CON EL MISMO, EL MENCIONADO SEGUNDO FLUJO DE GAS CONTIENE DE UN 5 A UN 25% EN VOLUMEN DE SO3; Y C) LA MEZCLA DE GAS OBTENIDA ES LUEGO SUMINISTRADA A UNA ETAPA DE CONTACTO DEL CONVERTIDOR, EN LA CUAL EL SO2 ES AL MENOS PARCIALMENTE CONVERTIDO A SO3 SOBRE UN CATALIZADOR. SE REFIERE ADEMAS, A UN APARATO PARA MEZCLAR DOS GASES EN UN CONVERTIDOR PARA PRODUCIR SO3 QUE COMPRENDE: i) UN CONDUCTO DE SUMINISTRO PARA UN PRIMER GAS, ii) UN CONVERTIDOR, iii) UN INTERCAMBIADOR DE CALOR, Y iv) UNA CAMARA DE MEZCLADOREFERS TO A PROCESS TO MIX TWO GASES OF DIFFERENT TEMPERATURES AND / OR COMPOSITIONS IN A CONVERTER TO PRODUCE SO3 FROM A GAS THAT HAS SO2, CHARACTERIZED BECAUSE: A) A FIRST FLOW OF GAS CONTAINING SO2 IN THE CONVERTER IS INTRODUCED THROUGH A CENTRAL SUPPLY PIPE AND PASSED THROUGH AN INTEGRATED HEAT EXCHANGER, SAID FIRST GAS FLOW CONTAINS MORE THAN 13% BY VOLUME OF SO2; B) THE SECOND GAS FLOW IS SUPPLIED VIA A RING DUCT PLACED IN THE CONVERTER DIRECTLY BEFORE OR AFTER THE INTEGRATED HEAT EXCHANGER, FROM WHICH THE SECOND GAS FLOW IS DISCHARGED THROUGH A PLURALITY OF THE OPENING AND IS INTO THE OPENING. FIRST GAS FLOW, IN SUCH A WAY THAT IT IS MIXED WITH IT, THE MENTIONED SECOND GAS FLOW CONTAINS FROM 5 TO 25% BY VOLUME OF SO3; AND C) THE GAS MIXTURE OBTAINED IS THEN SUPPLIED TO A CONTACT STAGE OF THE CONVERTER, IN WHICH SO2 IS AT LEAST PARTIALLY CONVERTED TO SO3 OVER A CATALYST. IT ALSO REFERS TO AN APPARATUS FOR MIXING TWO GASES IN A CONVERTER TO PRODUCE SO3, INCLUDING: i) A SUPPLY PIPE FOR A FIRST GAS, ii) A CONVERTER, iii) A HEAT EXCHANGER, AND iv) A MIXING CHAMBER
