Abstract
Se refiere a la polimerizacion continua de olefinas en lecho fluidizado con gas, especialmente etileno, propileno o mezclas de éstos con otras alfa-olefinas, en el que el gas de recirculacion que contiene el monomero empleado para fluidizar ellech o se hace pasar por un separador. El separador se cargacon, y se mantiene al menos parcialmente lleno de líquido. Las partículas de catalizador y/o polímero arrastradas se separan del gas de recirculacion en elseparador y estas partículasseparada s se mantienen en suspension en el líquido del separador. La corriente de recirculacion puede enfriarse hastacondensar al menos parte de los hidrocarburos líquidos; el líquido condensado, que puede ser un monomero o un líquidoinerte, se sep ara del gas derecirculacion en el separador y se alimenta directamente al lecho para producir el enfriamiento por el calor latente de vaporizacion. El procedimiento reducelas incrustaciones en el separador.
