Abstract
REFERIDO A UN PROCESO PARA OBTENCION DE ACIDO SULFURICO A PARTIR DE UN GAS QUE CONTIENE DIOXIDO DE AZUFRE, EN DONDE EL DIOXIDO DE AZUFRE ES OXIDADO CATALITICAMENTE EN UN CONVERTIDOR PARA OBTENER TRIOXIDO DE AZUFRE, EL CUAL ES ABSORBIDO EN ACIDO SULFURICO CONCENTRADO EN UN ABSORBEDOR INTERMEDIO Y EL GAS RESIDUAL ES SUMINISTRADO DE NUEVO PREFERENTEMENTE A UNA ETAPA DE CONVERSION CATALITICA, Y EN DONDE EL TRIOXIDO DE AZUFRE PRODUCIDO ES LUEGO ABSORBIDO EN ACIDO SULFURICO CONCENTRADO EN UN ABSORBEDOR FINAL. LA CONCENTRACION DE ENTRADA DEL ACIDO AL ABSORBEDOR INTERMEDIO ES DE 97,3 A 98,4 % DE H2SO4, Y EL AGUA REQUERIDA PARA FORMAR ACIDO SULFURICO A PARTIR DE TRIOXIDO DE AZUFRE Y PARA LA DILUCION HASTA CERCA DE UN 98,5 % DE H2SO4 ES EN PARTE OBTENIDA DE LA HUMEDAD DEL GAS/AIRE ABSORBIDA EN LA TORRE DE SECADO. SE DESCRIBE ADEMAS, UNA PLANTA PARA OBTENER ACIDO SULFURICO, EN DONDE LA TORRE DE SECADO INCLUYE UN CIRCUITO DE ACIDO SEPARADO DEL ABSORBEDOR Y DONDE UNA TUBERIA DE CONTRAFLUJO ES RAMIFICADA DESDE EL CIRCUITO DE ACIDO DE LA TORRE DE SECADO, LA CUAL ES CONECTADA CON LA TUBERIA DE SUMINISTRO DE ACIDO DEL ABSORBEDORREFERRED TO A PROCESS FOR OBTAINING SULFURIC ACID FROM A GAS CONTAINING SULFUR DIOXIDE, WHERE THE SULFUR DIOXIDE IS CATALYTICALLY OXIDIZED IN A CONVERTER TO OBTAIN SULFURED SULFURED ABSURBED TRIOXIDE IN ABSORBED SODIUM IN A CUAL ABSURED AND THE RESIDUAL GAS IS SUPPLIED AGAIN PREFERENTLY TO A CATALYTIC CONVERSION STAGE, AND WHERE THE PRODUCED SULFUR TRIOXIDE IS THEN ABSORBED IN CONCENTRATED SULFURIC ACID IN A FINAL ABSORBER. THE INPUT CONCENTRATION OF THE ACID TO THE INTERMEDIATE ABSORBER IS 97.3 TO 98.4% H2SO4, AND THE WATER REQUIRED TO FORM SULFURIC ACID FROM SULFUR TRIOXIDE AND FOR DILUTION TO CLOSE TO 98.5% H2SO4 IT IS IN PART OBTAINED FROM THE MOISTURE OF THE GAS / AIR ABSORBED IN THE DRYING TOWER. IT IS ALSO DESCRIBED, A PLANT TO OBTAIN SULFURIC ACID, WHERE THE DRYING TOWER INCLUDES A CIRCUIT OF ACID SEPARATED FROM THE ABSORBER AND WHERE A COUNTERFLOW PIPE IS BRANCHED FROM THE ACID CIRCUIT OF THE DRYING TOWER, WITH WHAT IS CONNECTED ABSORBER ACID SUPPLY LINE
