Abstract

La invencion se refiere a la polimerizacion continua de olefinas en lecho fluidizado con gas, especialmente etileno, propileno o mezclas de estos con otras alfa-olefinas, en el que el gas de recirculacion que contiene el monomero empleado para fluidizar el lecho se hace pasar por un separador. El separador se carga con, y se mantiene al menos parcialmente lleno de, líquido. Las partículas de catalizador y/o polímero arrastradas se separan del gas de recirculacion en el separador y éstas partículas separadas se mantienen en suspension en el líquido del separador. La corriente de recirculacion puede enfriarse hasta condensar al menos parte de los hidrocarburos líquidos; el líquido condensado, que puede ser un monomero o un líquido inerte, se separa del gas de recirculacion en el separador y se alimenta directamente al lecho para producir el enfriamiento por el calor latente de vaporizacion. el procesamiento reduce las incrustaciones en el separador.
