Abstract
METODO PAREA LA RECUPERACION DE PRODUCTOS QUIMICOS DE CALDOS AGOTADOS DE PASTA DE PAPEL, MIENTRAS SE UTILIZA AL MISMO TIEMPO LA ENERGIA LIBERADA DURANTE EL PROCESO. COMPRENDE LAS SIGUIENTES OPERACIONES: PRIMERA, UN FUNDIDO RESULTANTE DE LA GASIFICACION Y DESINTEGRACION PARCIAL DE LOS CALDOS AGOTADOS DE PULPA DE PAPEL SE INTRODUCE, JUNTO CON ENERGIA TERMICA EXTERNA INDEPENDIENTE DE LA COMBUSTION, EN LA ZONA DE REACCION DE UN REACTOR; SEGUNDA, EN LA COMBUSTION PRODUCIDA EN EL REACTOR SE DESPRENDEN LOS PRODUCTOS QUIMICOS EN ESTADO GASEOSO; Y POR ULTIMO, EL PRODUCTO GASEOSO SE APAGA EN UNA ZONA DE APAGADO PREVISTA EN EL REACTOR Y A CONTINUACION SE ENFRIA A UNA TEMPERATURA INFERIOR A 950 GRADOS.
