Abstract

UN PROCEDIMIENTO MULTILECHO DE ELIMINACION DE OXIDO DE AZUFRE Y/O OTROS COMPUESTOS QUE CONTIENEN AZUFRE COMBUSTIBLES DE UN FLUJO DE GAS (10) QUE CONSISTE EN LA COMBUSTION DE LOS OTROS COMPUESTOS CUANDO PRESENTAN OXIDO DE AZUFRE, CON LO QUE SE FORMA UN FLUJO ENRIQUECIDO DE OXIDO DE AZUFRE (19). EL FLUJO SE PONE EN CONTACTO CON UN PRIMER Y UN SEGUNDO LECHO ABSORBENTE SOLIDO CONECTADO EN SERIE (22, 25) PARA ABSORBER LOS OXIDOS DE AZUFRE EN FORMA DE SULFATOS INORGANICOS Y/O OXIDOS DE AZUFRE. EL FLUJO DE ALIMENTACION SE REALINEA ENTONCES PARA COLOCAR EL SEGUNDO Y UN TERCER LECHO (32) EN SERIE CON EL FLUJO DE GAS MIENTRAS QUE EL PRIMER LECHO ES COLOCADO EN UN MODO REGENERADOR. EL LECHO ABSORBENTE REGENERADOR SE PONE EN CONTACTO CON UN AGENTE REDUCTOR PARA REDUCIR LOS COMPUESTOS DE AZUFRE ABSORBIDOS EN SULFURO DE HIDROGENO Y/O DIOXIDO DE AZUFRE. LAS ETAPAS SE REPITEN HASTA QUE CADA UNO DE LOS LECHOS SON COLOCADOS EN UN PRIMER MODO ABSORBENTE, UN SEGUNDO MODO ABSORBENTE Y UN MODO REGENERADO.
