Abstract

PROCEDIMIENTO PARA SEPARAR PARTICULAS DE CARBON DE CENIZA VENTILADA MEDIANTE FLOTACION EN AGUA QUE CONTIENE COLECTOR Y ESPUMADOR. LA FLOTACION SE REALIZA BAJO VIGOROSA AIREACION Y POR LO MENOS EN DOS OPERACIONES, AJUSTANDOSE EL PH EN LA PRIMERA OPERACION A UN VALOR DE 6 A 8 Y EN LA SEGUNDA OPERACION A UN VALOR INFERIOR AL DE LA PRIMERA Y A LO SUMO DE 6,5. EL PH SE AJUSTA ENTERA O PARCIALMENTE CON AYUDA DE ACIDO SULFORICO O MEDIANTE LA INTRODUCCION DE GASES DE CHIMENEA ACIDOS, USANDOSE GASOIL COMO COLECTOR Y ACEITE DE PINO VEGETAL O SINTETICO COMO ESPUMADOR.
