Abstract

PROCEDIMIENTO PARA LA PRODUCCION DE PIEDRA CALIZA FINAMENTE DIVIDIDA PARA SU APLICACION EN EL TRATAMIENTO DE GASES EN SECO PARA SU PURIFICACION. CONSISTE EN TRITURAR LA PIEDRA CALIZA EN UNA LECHADA ACUOSA EN PRESENCIA DE DIOXIDO DE CARBONO DISUELTO Y/O EN PRESENCIA DE UN MATERIAL FORMADOR DE ACIDO Y UTILIZANDOSE UN MOLINO VERTICAL Y UN ATOMIZADOR ROTATIVO, PRODUCIENDOSE PARTICULAS DE CARBONATO CALCICO QUIMICAMENTE PURO DE DIAMETRO DE PARTICULA INFERIOR A 5 MICRAS. SE USA EN EL DESAZUFRADO DE GASES DE COMBUSTION EN SECO.
