Abstract

La presente invencion proporciona un procedimiento en lecho fluidizado por gas continuo para la polimerizacion de monomeros de olefina seleccionados entre (a) etileno, (b) propileno, (c) mezclas de etileno y propileno, y (d) una o más alfa-olefinas distintas mezcladas con (a), (b) o (c), para producir un polímero en un reactor de lecho fluidizado, comprendiendo el procedimiento, (0) extraccion continua del reactor de una corriente gaseosa compuesta por monomero de olefina sin reaccionar y que arrastra catalizador y/o partículas de polímero; (i) recirculacion continua de dicha corriente gaseosa compuesta por monomero de olefina sin reaccionar a través de un lecho fluidizado en dicho reactor, en presencia de un catalizador de polimerizacion en condiciones de reaccion; (2) enfriamiento por medio de intercambiador(es) de calor de al menos parte de dicha corriente gaseosa extraída de dicho reactor hasta una temperatura a la que el líquido condense; (3) separacion de al menos parte del líquido condensado de la corriente gaseosa, o (4) introduccion de al menos parte del líquido separado directamente en el lecho fluidizado, caracterizado porque, al menos parte del líquido separado se reintroduce en la corriente gaseosa de recirculacion antes de dicho(s) intercambiador(es) de calor.
