Abstract

Proceso para la polimerizacion de etileno o de etileno con otras 1-olefinas, en el cual el etileno se polimeriza en la presencia de un catalizador en un reactor de fase gaseosa y un gas de reaccion que comprende propano y etileno no polimerizado se hace circular para extraer el calor de polimerizacion, en donde las partículas de polímero se descargan en forma continua o discontinua desde el reactor, las partículas de polímero se separan de la parte principal del gas concomitante descargado y las partículas de polímero se desgasifican, el gas se libera de las partículas finas transportadas y se separa de una fraccion de baja ebullicion que comprende etileno o de una fraccion de alta ebullicion que contiene otras 1-olefinas o alcanos con 4 a 12 átomos de carbono en una primera etapa de separacion, una fraccion de propano se separa en una segunda etapa de separacion y esta fraccion de propano se usa para desgasificar las partículas de polímero descargadas del reactor, con la proporcion de etileno en la fraccion de propano inferior a 1% en moles y la proporcion de 1-olefinas y alcanos con 4 a 12 átomos de carbono en la fraccion de propano inferior a 4% en moles, en cada caso en base a la fraccion total de propano. Además, un aparato para llevar a cabo el proceso. De esta manera, es posible una elevada descarga de calor desde el reactor, la satisfactoria desgasificacion de las partículas de polímero descargadas y la recuperacion del gas de reaccion descargado junto con las partículas de polímero y también el gas usado para desgasificar las partículas de polímero.
