Abstract
SE LLEVA A LA INSTALACION DE HIDROGENACION UNA DISPERSION CONTENIENDO LOS ACIDOS GRASOS Y/O SUS DERIVADOS, HIDROGENO, UN CATALIZADOR NO USADO, Y UN CATALIZADOR USADO, Y A TEMPERATURAS DE ENTRE 100 Y 400 BTIENE UN FLUJO DE PRODUCTO QUE CONTIENE ALCOHOLES GRASOS Y EL CATALIZADOR USADO. EL FLUJO DE PRODUCTO SE HACE RECIRCULAR PARCIALMENTE, EXTRAYENDO DE ESTA RECIRCULACION UN PRIMER FLUJO PARCIAL CON CANTIDADES REGULABLES Y DIRIGIENDOLO HACIA UN DISPOSITIVO SEPARADOR. DE ESTE SALE UN PRODUCTO RICO EN ALCOHOL GRASO, Y SEPARADO DE EL UNA DISPERSION CONTENIENDO UN CATALIZADOR USADO, QUE SE VUELVE A LLEVAR A LA INSTALACION DE HIDROGENACION. DE LA RECIRCULACION DEL FLUJO DE PRODUCTO SE EXTRAE UN SEGUNDO FLUJO PARCIAL CON CANTIDADES REGULABLES Y DE AHI SE SEPARA UN CATALIZADOR USADO, QUE SE ALEJA DEFINITIVAMENTE DEL PROCESO. PARA AUMENTAR LAS CANTIDADES DE CATALIZADOR REDIRIGIDO HACIA LA INSTALACION DE HIDROGENACION, SE REDUCE LA CANTIDAD EL SEGUNDO FLUJO PARCIAL.
