    • A process for liquid-liquid extraction of an oil-blend of non-uniform oligomeric and polymeric components, wherein "non-uniform" means that the components may have a varying size, shape and mass distribution, the process comprising a separation step wherein heavy components and light components in the oil-blend having similar chemical functionalities are separated to produce a heavy components fraction and a light components fraction, wherein the process comprises the steps (a) to (e): (a) preselecting a desired molecular weight (Mw) boundary between heavy and light components; (b) selecting an extractive solvent or an extractive mixture of solvents, which form essentially a single phase with the light components, such that at least 80% of the light components are dissolved, at elevated temperature, being the fractionation temperature, and in which the heavy components are essentially immiscible at the fractionation temperature, such that at most 10% of the heavy components are dissolved at said temperature in an amount of the extractive solvent / mixture of solvents in which the light components are fully dissolved at that temperature; (c) mixing the oil-blend and the extractive solvent or extractive mixture of solvents selected in step (b) at elevated temperature, which is at least at or above said fractionation temperature, and wherein the extractive solvent / mixture of solvents to oil-blend ratio is from 1:2 to 100:1; (d) allowing a phase split to form between the heavy components fraction and the light components/extractive solvent fraction at the fractionation temperature or at most 10 °C below the fractionation temperature; (e) followed by separation of said fractions.

    • An adsorptive separation process and system are used for separation of multi- component fluid mixtures. The separation process and system may include establishing, in a fluid flow within the system, a concentration distribution of the fluid mixture components based upon the components' relative affinities to the adsorbent. The concentration distribution could be establishing using a simulated moving bed system, wherein it is possible to maintain separately-identifiable portions of the fluid flow, respectively rich in strongly- adsorbing, intermediately-adsorbing, and weakly-adsorbing compounds of the fluid mixture. An intermediate raffinate of high purity in the intermediately-adsorbing compound is directly withdrawn from the portion of the fluid flow rich in intermediately-adsorbing compound(s), providing a single-stage adsorptive separation of a compound having intermediate affinity to the adsorbent. The portion of the fluid flow rich in intermediately-adsorbing compound(s) may be established directly upstream from the point of fluid mixture feed injection into the fluid flow.
    • 吸附分离过程和系统用于分离多组分流体混合物。 分离过程和系统可以包括基于组分对吸附剂的相对亲和力在系统内的流体流中建立流体混合物组分的浓度分布。 可以使用模拟移动床系统建立浓度分布,其中可以保持流体流动的可分离识别的部分,分别富含强吸附,中间吸附和弱吸附的流体混合物的化合物。 在中间吸附化合物中的高纯度中间残液直接从富含中间吸附化合物的流体流的部分排出,从而提供对吸附剂具有中等亲和性的化合物的单阶段吸附分离。 富含中间吸附化合物的流体流的部分可以直接从流体混合物进料注入到流体流中的上游建立。
