    • A solution polymerization process that consumes less energy comprising: injecting feeds into one or more reactors to form a polyethylene in a single liquid phase, or optionally two liquid phases; deactivating the single or dual liquid phase; a first V/L separator separates the deactivated phase into a first bottom stream and a first overhead stream; the first overhead stream passes to a distillation column and the first bottom stream enters a second V/L separator, forming a second overhead stream and a second bottom stream; the second bottom stream enters a third V/L separator, forming a third overhead stream and a third bottom stream; the third bottom stream passes to polymer recovery; the second and third overhead stream are combined, condensed and purified, forming a purified solvent that is recycled to said reactors.
    • 消耗更少能量的溶液聚合方法包括:将进料注入一个或多个反应器以在单个液相或任选两个液相中形成聚乙烯; 停用单液或双液相; 第一V / L分离器将去活化相分离成第一底部流和第一塔顶流; 第一塔顶流通入蒸馏塔,第一塔底物流进入第二V / L分离器,形成第二塔顶流和第二塔底料流; 第二底部流进入第三V / L分离器,形成第三塔顶流和第三底部流; 第三个底部流进入聚合物回收; 将第二和第三塔顶流合并,浓缩和纯化,形成再循环到所述反应器的纯化溶剂。

    • Disclosed are a device and a method for continuously polymerizing polybutene by removing halogen acid, which is included in a reaction raw material, by adsorbing the halogen acid using an adsorbent and then re-supplying the reaction raw material into a reactor. The device for re-circulating the raw material when manufacturing polybutene comprises a reactor, into which a catalyst and a reaction raw material (diluted with an inactive organic solvent) are supplied and polymerized to produce a reaction product; a neutralizing/washing tank for removing the catalyst from the reaction product and neutralizing the reaction product; a separation tank for separating the reaction product into organic compounds and water; a C4 distillation column for distilling an unreacted raw material and the inactive organic solvent from the organic compounds; and an impurity adsorption column for removing halogen acid from the distilled unreacted raw material and the inactive organic solvent using an adsorbent.
    • 公开了通过使用吸附剂吸附卤酸,然后将反应原料再供给到反应器中,通过除去反应原料中所含的卤素酸来连续聚合聚丁烯的装置和方法。 当制备聚丁烯时,用于再循环原料的装置包括反应器,其中供应催化剂和反应原料(用惰性有机溶剂稀释)并聚合以产生反应产物; 用于从反应产物中除去催化剂并中和反应产物的中和/洗涤槽; 用于将反应产物分离成有机化合物和水的分离罐; 用于从有机化合物中蒸馏未反应的原料和无活性有机溶剂的C4蒸馏塔; 以及使用吸附剂从蒸馏的未反应原料和无活性有机溶剂中除去卤素酸的杂质吸附塔。
