In spite of significant advancements in the synthesis of lab-scale polymeric membranes for CO separation, only a limited number of studies have transitioned to pilot-scale studies. Fabricating membrane modules is a critical step in realizing the commercialization of gas separation membranes for post-combustion carbon capture, yet specific details regarding this process are rarely demonstrated. In this study, a commercial-size ⌀8ʺ prototype of countercurrent sweep spiral-wound (SW) membrane module with an amine-containing facilitated transport membrane was successfully fabricated. The module comprised 41 membrane leaves, each with a width of 20ʺ and a length of 36ʺ, resulting in a total effective membrane area of 35 m. To ensure an even distribution of sweep flow on the permeate side to minimize pressure drop, a new epoxy glue dot line pattern was strategically designed to create a countercurrent flow configuration. The SW membrane module exhibited consistent transport performance aligning with the results of the flat-sheet membrane. The successful fabrication of the commercial-size prototype highlights the exceptional potential and effectiveness of the developed full-scale membrane module in effectively tackling the challenges associated with CO capture from flue gas.

用于烟气二氧化碳捕集的商业规模逆流螺旋卷式膜组件原型

尽管用于 CO 分离的实验室规模聚合物膜的合成取得了重大进展，但只有有限数量的研究转变为中试规模研究。制造膜组件是实现燃烧后碳捕获气体分离膜商业化的关键步骤，但有关该过程的具体细节很少得到证实。在这项研究中，成功​​制造了带有含胺促进传输膜的商业尺寸⌀8ʺ逆流扫式螺旋缠绕（SW）膜组件原型。该组件由 41 个膜叶组成，每个膜叶宽度为 20ʺ，长度为 36ʺ，总有效膜面积为 35 m。为了确保渗透侧的吹扫流量均匀分布，从而最大限度地减少压降，我们战略性地设计了一种新的环氧树脂胶点线图案，以创建逆流流动配置。SW 膜组件表现出一致的传输性能，与平板膜的结果一致。商业尺寸原型的成功制造凸显了所开发的全尺寸膜组件在有效应对烟气中二氧化碳捕集相关挑战方面的非凡潜力和有效性。
