    • The present invention relates to a process for treating polyolefin granules in a treatment vessel comprising the steps of: —Providing a bed of granules in liquid in said treatment vessel —Withdrawing a first stream of liquid from said treatment vessel, wherein said first stream of liquid contains hydrocarboneous compounds —introducing a first stream of vapor into said treatment vessel —Withdrawing a second stream of vapor from said treatment vessel wherein said second stream of vapor contains volatile hydrocarboneous compounds —Recovering the granules from said treatment vessel wherein said first stream of vapor has a temperature from Tb to Tb+10° C., wherein Tb is the boiling point of the liquid at the applied pressure, and said first stream of vapor produces an upwards rising vapor stream in said treatment vessel, the superficial vapor velocity of which is no more than 0.2 m/s, and a plant suitable for conducting said process.
    • 本发明涉及一种在处理容器中处理聚烯烃颗粒的方法,包括以下步骤: - 在所述处理容器中提供液体中的颗粒床 - 从所述处理容器中抽出第一液体流,其中所述第一液体流 包含烃类化合物 - 将第一蒸汽流引入所述处理容器中 - 从所述处理容器中抽出第二蒸气流,其中所述第二蒸气流含有挥发性烃类化合物 - 从所述处理容器中除去所述颗粒,其中所述第一蒸汽流具有 Tb到Tb + 10℃的温度,其中Tb是在施加压力下的液体的沸点,并且所述第一蒸气流在所述处理容器中产生向上升的蒸气流,其蒸汽速度为 不超过0.2m / s,适用于进行所述方法的植物。
