链烷烃烷基化方法
摘要：
公开了一种链烷烃烷基化方法，其中异丁烷供应给两个单独的烷基化系统。第一烷基化系统的流出物供应给中间脱丁烷塔，此处从烷基化产物中分离出C4组分。然后将塔顶C4产物供应给第二烷基化系统以提供异丁烷。第二烷基化系统的流出物供应给传统的脱异丁烷塔以防止正丁烷在系统内的任何累积。
摘要（英）：

A process for the alkylation of isobutane is disclosed wherein isobutane is fed to two separate alkylation systems. The effluent from the first alkylation system is fed to an interim debutanizer where the C4's are separated from the alkylate product. The overhead C4 product is then fed to the second alkylation system to provide the isobutane. The effluent from the second alkylation system is fed to a traditional deisobutanizer to prevent any build up of normal butanes in the system.
