Abstract

PROCEDIMIENTO DE REACCION EN SECO DE SLAMS DE ASBESTO Y SULFATO DE AMONIO. CONSISITE EN MEZCLAR SLAMS DE ASBESTO Y SULFATO DE AMONIO EN UNA SUPERFICIE PLANA, CALIENTE Y CORRUGADA DESDE UNA TEMPERATURA AMBIENTE HASTA OTRA COMPRENDIDA ENTRE LOS 350 G Y LOS 400 G, PARA FORMAR SULFATO DE MAGNESIO AL ALCANZAR LA TEMPERATURA DE 250 G Y DESPRENDIENDOSE AMONIACO. A PARTIR DE LOS 250 G EL SULFATO DE AMONIO SE DESCOMPONE EN AMONIACO GASEOSO Y BISULFATO DE AMONIO SUBLIMADO, QUE SE CONDENSA Y RECCIONA CON EL AMONIACO GASEOSO, FORMANDO DE NUEVO EL SULFATO AMONICO. EL PROCESO ES REPETITIVO Y SE SIGUE PRODUCIENDOSE HASTA QUE LA TEMPERATURA DE LA ZONA MAS ALEJADA ALCANZA DE 250 G A 300 G Y SE RECOGE EL SULFATO DE MAGNESIO DE LA MEZCLA REACCIONAL. T
