Abstract
LA SEPARACION DE UNA CORRIENTE DE MULTIPLES COMPONENTES MEDIANTE DESTILACION UTILIZANDO UN SISTEMA DE DESTILACION DE MULTIPLES COLUMNAS QUE COMPRENDE UN SISTEMA DE COLUMNA PRINCIPAL (12) Y UNA COLUMNA LATERAL (22) SE MEJORA ACOPLANDO TERMICAMENTE EL SISTEMA DE COLUMNA PRINCIPAL (12) Y EL SISTEMA DE COLUMNA LATERAL (22) MEDIANTE UNA CALDERA/CONDENSADOR (32) EN DONDE SE CONDENSA AL MENOS UNA PARTE DE FRACCION DE VAPOR (34) DEL SISTEMA DE COLUMNA PRINCIPAL FRENTE A UNA FRACCION LIQUIDA (28) DE LA COLUMNA LATERAL (22). LA FRACCION CONDENSADA RESULTANTE (40) Y LA FRACCION VALORIZADA SE DEVUELVEN AL SISTEMA DE COLUMNA PRINCIPAL (12) Y COLUMNA LATERAL (22) RESPECTIVAMENTE. SE PUEDEN DAR MAS DE UNA INTEGRACION TERMICA A DIFERENTES NIVELES EN DICHA COLUMNAS (12,22).
