Abstract
METODO PARA RECUPERAR PRODUCTOS QUIMICOS ALCALINOS DE LOS GASES DE COMBUSTION CONTENIENDO VAPORES DE METAL ALCALINO. COMPRENDE: A) GASIFICAR EL MATERIAL EN UN REACTOR MEDIANTE UNA FUENTE EXTERNA DE CALOR A UNA TEMPERATURA DE 1.000º, PRODUCIENDOSE ASI GAS CONTENIENDO CO, CO2 Y H2S, EN EL CUAL EL SODIO Y POTASIO ESTAN EN ESTADO GASEOSO; B) REFRIGERAR EL GAS MEDIANTE LA DISPOSICION DEL MISMO EN CONTACTO CON UNA ADECUADA CANTIDAD DE PARTICULAS SOLIDAS RECIRCULADAS ENFRIADAS, QUE SON SEPARADAS DEL GAS PARA DISMINUIR LA TEMPERATURA DEL GAS RAPIDAMENTE POR DEBAJO DE LA TEMPERATURA DE SUBLIMACION DE LOS COMPUESTOS DE SODIO O POTASIO Y PRODUCIENDO UNA MEZCLA SOLIDA CONTENIENDO SUSTANCIALMENTE NAOH, NA2S, QUE LUEGO PUEDE SER UTILIZADO PARA COCCION DE CELULOSA.
