Abstract
DESULFURACION CATALITICA DE NAFTA CRAQUEADA CON UNA PERDIDA MINIMA DE OLEFINAS Y OCTANO. SE DOSIFICA LA NAFTA EN EL PRIMER REACTOR DE UNA COLUMNA DE DESTILACION (10), QUE ACTUA COMO DESPENTANIZADOR O DESHEXANIZADOR, LLEVANDO A EBULLICION EL MATERIAL MAS LIGERO QUE CONTIENE LA MAYOR PARTE DE OLEFINAS Y MERCAPTANOS EN UNA PRIMERA ZONA DE REACCION DE LA DESTILACION (11), DONDE SE HACEN REACCIONAR LOS MERCAPTANOS CON LAS DIOLEFINAS PARA FORMAR SULFUROS, QUE SE ELIMINAN DEL FONDO JUNTO CON CUALQUIER OTRO COMPUESTO AZUFRADO CON UN PUNTO DE EBULLICION MAS ELEVADO. LOS RESIDUOS DEL FONDO SE SOMETEN A UNA HIDRODESULFURACION EN EL SEGUNDO REACTOR DE UNA COLUMNA DE DESTILACION (20), DONDE LOS COMPUESTOS DE AZUFRE SE CONVIERTEN EN H 2 S Y SE ELIMINAN. LA FRACCION MAS LIGERA QUE CONTIENE LA MAYOR PARTE DE LAS OLEFINAS NO SE SOMETE, POR TANTO, A LAS CONDICIONES DE HIDROGENACION MAS RIGUROSAS DEL SEGUNDO REACTOR (20).
