Abstract
SE PRODUCEN POLIOLEFINAS POR UN PROCESO QUE COMPRENDE LAS ETAPAS DE: POLIMERIZACION DE OLEFINAS EN UNA ZONA DE REACCION A: ELIMINAR LA OLEFINA NO REACCIONADA DEL POLIMERO EN UNA CAMARA DE INFLAMACION B Y SE RECICLA OLEFINA NO REACCIONADA EN LA ZONA DE REACCION A; SE RETIRA LA OLEFINA NO REACCIONADA DEL POLIMERO PASANDO UN GAS DE ESTABILIZACION A TRAVES DE UNA ZONA DE ESTABILIZACION C; SE PASA LA OLEFINA NO REACCIONADA DE LA ZONA DE ESTABILIZACION A PRESION SUPERATMOSFERICA A TRAVES DE UN SEPARADOR DE GAS D QUE ALOJA UN LECHO ADSORBENTE QUE SELECTIVAMENTE ABSORBE OLEFINAS. SE DESPRESURIZA EL ADSORBENTE PARA PRODUCIR UNA OLEFINA SUSTANCIALMENTE PURA Y RECICLAR LA OLEFINA SUSTANCIALMENTE PURA EN LA ZONA DE REACCION A; SE PURGA EL LECHO ADSORBENTE CON UN GAS NO ABSORBIBLE; Y SE PASA LA MEZCLA DE OLEFINA NO REACCIONADA-GAS DE PURGA RESULTANTE A LA ZONA DE ESTABILIZACION B PARA SER USADA COMO GAS DE ESTABILIZACION.
