Abstract

SE REFIERE A UN PROCESO PARA MEZCLAR DOS GASES DE DIFERENTE TEMPERATURA Y/O COMPOSICION EN UN CONVERTIDOR PARA PRODUCIR SO3 A PARTIR DE UN GAS QUE CONTIENE SO2, QUE COMPRENDE: A) INTRODUCIR UN PRIMER FLUJO DE GAS DENTRO DE UNA CAMARA DE MEZCLADO EN UNA PRIMERA DIRECCION; B) INTRODUCIR UN SEGUNDO FLUJO DE GAS A CONTRACORRIENTE DENTRO DE LA CAMARA DE MEZCLADO EN UNA DIRECCION OPUESTA A LA PRIMERA; C) DESCARGAR LA MEZCLA DE GAS OBTENIDA EN LA CAMARA DE MEZCLADO, DESDE LA CAMARA DE MEZCLADO, VIA UN TUBO DE CONEXION QUE SE EXTIENDE EN LA PRIMERA DIRECCION; Y D) SUMINISTRAR DICHA MEZCLA A UN INTERCAMBIADOR DE CALOR INTEGRADO EN EL CONVERTIDOR. SE REFIERE ADEMAS, A UN APARATO PARA MEZCLAR DOS GASES EN UN CONVERTIDOR PARA PRODUCIR SO3, A PARTIR DE UN GAS QUE CONTIENE SO2, QUE COMPRENDE: a) UNA CAMARA MEZCLADORA A LA CUAL SE SUMINISTRA UN PRIMER FLUJO DE GAS EN UNA PRIMERA DIRECCION; Y b) UN CONDUCTO DE SUMINISTRO PARA UN SEGUNDO FLUJO DE GAS; EN DONDE, LA CAMARA DE MEZCLADO SE PROPORCIONA EN LA FORMA DE UN ANILLO ALREDEDOR DEL CONDUCTO DE SUMINISTRO EL CUAL SE CONECTA CON EL CONDUCTO DE SUMINISTRO, E INCLUYE UN TUBO DE CONEXION QUE SE EXTIENDE DESDE LA CAMARA DE MEZCLADO EN LA PRIMERA DIRECCION, EN PARTICULAR DESDE ABAJO HACIA ARRIBA, Y QUE ES CONECTADA LA CAMARA DE MEZCLADO CON UN INTERCAMBIADOR DE CALOR INTEGRADOREFERS TO A PROCESS TO MIX TWO GASES OF DIFFERENT TEMPERATURE AND / OR COMPOSITION IN A CONVERTER TO PRODUCE SO3 FROM A GAS CONTAINING SO2, WHICH INCLUDES: A) INTRODUCING A FIRST GAS FLOW INTO A CHAMBER FIRST DIRECTION; B) INTRODUCE A SECOND COUNTER-CURRENT GAS FLOW INTO THE MIXING CHAMBER IN A DIRECTION OPPOSITE TO THE FIRST; C) DISCHARGE THE GAS MIXTURE OBTAINED IN THE MIXING CHAMBER, FROM THE MIXING CHAMBER, VIA A CONNECTION TUBE THAT EXTENDS IN THE FIRST DIRECTION; AND D) SUPPLY SAID MIXTURE TO A HEAT EXCHANGER INTEGRATED IN THE CONVERTER. IT ALSO REFERS TO AN APPARATUS FOR MIXING TWO GASES IN A CONVERTER TO PRODUCE SO3, FROM A GAS CONTAINING SO2, INCLUDING: a) A MIXING CHAMBER TO WHICH A FIRST FLOW OF GAS IS SUPPLIED IN A FIRST DIRECTION; AND b) A SUPPLY PIPE FOR A SECOND GAS FLOW; WHERE, THE MIXING CHAMBER IS PROVIDED IN THE FORM OF A RING AROUND THE SUPPLY DUCT WHICH CONNECTS WITH THE SUPPLY DUCT, AND INCLUDES A CONNECTING TUBE THAT EXTENDS FROM THE MIXING CHAMBER IN THE FIRST DIRECTION PARTICULAR FROM BOTTOM TO TOP, AND THAT THE MIXING CHAMBER IS CONNECTED WITH AN INTEGRATED HEAT EXCHANGER
