Abstract

DISPOSITIVO PARA POLIMERIZAR ETILENO. CONSTA DE UN PRIMER REACTOR CON INYECTOR DE CATALIZADOR, UN SEGUNDO REACTOR TAMBIEN DOTADO CON INYECTOR DE CATALIZADOR, UNA VALVULA REDUCTORA DE PRESION SITUADA A LA SALIDA DEL PRIMER REACTOR, UN CONDUCTO QUE UNA LA VALVULA AL SEGUNDO REACTOR, UN SEPARADOR Y UN CONDUCTO QUE UNE LA SALIDA DEL SEGUNDO REACTOR AL SEPARADOR, UN CONDUCTO DE EVACUACION DEL POLIMERO EN LA BASE DEL SEPARADOR Y UN HIPERCOMPRESOR. EL INYECTOR COMPRENDE UNA TOBERA QUE FORMA EL EXTREMO DEL CONDUCTO QUE PROCEDE DE LA VALVULA REDUCTORA DE PRESION Y UNA ZONA DE MEZCLA CONVERGENTE DESPUES DE LA TOBERA DE INYECCION Y CONECTADA A UNA FUENTE DE ETILENO FRIO Y UN DIFUSOR.
