    • PURPOSE: Provided is a method for recovering two kinds of paraffin products by using two separation zones connected in parallel, which reduces the manufacturing and operation costs. CONSTITUTION: The method of adsorptive separation for recovering both a n-paraffin and a monomethyl paraffin from a charge stream comprises the steps of: (a) sending the charge stream to a first adsorptive separation zone to maintain a first paraffin hydrocarbon in the first phase of the selective absorbent, and to recover a branched and a cyclic hydrocarbons, a first raffinate stream and a first extract stream from the zone; (b) sending the paraffin hydrocarbon recovered from the first extract stream or the first raffinate stream to a second adsorptive separation zone to maintain a second paraffin hydrocarbon in the second phase of the selective absorbent, and to recover a second raffinate stream and a second extract stream from the zone; (c) fractionating the first and second extract streams and the first and second raffinate streams to recover the desorbing agent and to produce the first and second extract streams; and (d) sending the recovered desorbing agent to the first and second adsorptive separation zones to produce the first and second extract streams.
    • 目的:提供通过使用两个并联连接的分离区来回收两种石蜡产品的方法,这降低了制造和操作成本。 构成:从电荷流中回收正链烷烃和单甲基石蜡的吸附分离方法包括以下步骤:(a)将电荷流送至第一吸附分离区以保持第一相中的第一链烷烃 的选择性吸收剂,并从所述区域回收支链和环状烃,第一萃余液流和第一萃取物流; (b)将从第一提取物料流或第一萃余物料流回收的链烷烃送至第二吸附分离区,以在选择性吸收剂的第二相中维持第二链烷烃,并回收第二提取物流和第二提取物 从该区流出; (c)分级分离第一和第二提取物流和第一和第二残液物流以回收解吸剂并产生第一和第二提取物物流; 和(d)将回收的解吸剂送到第一和第二吸附分离区以产生第一和第二提取物流。
