Abstract
ES UN METODO PARA EXTRAER DIOXIDO DE AZUFRE DE UN CHORRO DE GASES EN UN SISTEMA HUMEDO DE DEPURACION, DONDE EL TIOSULFATO DE CALCIO Y LAS POLISULFIDAS SE FORMAN POR LA REACCION DE UNA CAL Y AZUFRE EMULSIONADO Y LA MEZCLA AÑADIDA AL TANQUE DE RECICLAJE DEL DEPURADOR HUMEDECIDO, REACCIONA CON LOS SULFITOS Y BISULFITOS EN EL MATERIAL DE SUSPENSION QUE SE ENCUENTRA EN EL SISTEMA DE DEPURACION PARA PRODUCIR TIOSULFATOS A PARTIR DE LAS POLISULFIDAS DE CALCIO, JUNTO CON EL MATERIAL EN SUSPENSION VUELVEN POSTERIORMENTE AL DEPURADOR. LA MEZCLA DEL TIOSULFATO CALCICO Y LAS POLISULFIDAS CALCICAS SE PUEDEN FORMAR EN EL TANQUE DE CAL APAGADA O EN EL TANQUE DE ALMACENAMIENTO DE LA CAL DEL SISTEMA DE DEPURACION, O TAMBIEN SE PUEDEN FORMAR EN UN TANQUE MEZCLADOR Y AÑADIRLA A LA CAL O AL SISTEMA DE DEPURACION DE CALIZA.
