摘要

本文介绍了一种新的非稳态膜气体分离方法的实验研究，该方法用于回收膜模块中具有周期性滞留物提取的慢渗透组分。案例研究包括使用径向逆流膜组件分离基于快速渗透的主要成分(氮气，c2h2)和慢渗透的杂质(1%体积的氮气)的二元测试混合物。新的半批提取技术被证明可以强化分离过程，与相同生产率的稳态操作相比，分离效率提高了40%。

Membrane gas separation module with pulsed retentate for low-permeable component recovery

The paper presents the experimentalstudy of a novel unsteady-statemembrane gas separation approach for recovery of a slow-permeant component in the membrane module with periodical retentate withdrawals. The case study consisted in the separation of binary test mixtures based on the fast-permeant main component (N 2 O, C 2 H 2 ) and the slow-permeant impurity (1% vol. of N 2 ) using a radial countercurrent membrane module. The novel semi-batch withdrawal technique was shown to intensify the separation process and provide up to 40% increase in separation eﬃciency compared to a steady-state operation of the same productivity.

期刊介绍： The content, aim and scope of the proposals should comply with the main subject of the journal, i.e. they should deal with mathematical modelling and/or experimental investigations on momentum, heat and mass transfer, unit processes and operations, integrated processes, biochemical engineering, statics and kinetics of chemical reactions. The experiments and modelling may cover different scales and processes ranging from the molecular phenomena up to production systems. The journal language is grammatically correct British English. Chemical and Process Engineering publishes: i) full text research articles, ii) invited reviews, iii) letters to the editor and iv) short communications, aiming at important new results and/or applications. Each of the publication form is peer-reviewed by at least two independent referees.
