SGER: Enhanced Scalability of Chemical Processes through Narrow-Gap Architectures

摘要：与管道相连的容器和储罐是目前化学过程工业的建筑范例。对于许多应用程序，类似的处理可以通过使用库和模块来扩展窄间隙架构来实现。PI计划研究窄间隙方法，这是一种大规模并行和模块化的化学过程构建方法。对于这种方法，单元操作，包括反应器、分离过程、混合和电化学过程，都设计在由板和面对面固定的垫圈组成的架构中。单位操作或单位操作之间的质量传递均匀地分布在各板块中，通常沿垂直于板块表面的方向进行。多个设计自由度由板和垫片的结构设置-解决流动模式，停留时间分布，传热过程和脱离过程。这个探索性研究项目的小额资助的目标是：(1)构建一个工作模块来展示这个概念，并说明窄间隙方法优于传统的工艺体系结构；(2)评估和开发该体系结构特有的工艺，如基于多孔介质的塞流反应器、膜集成和流体流动网络。为了验证该方法，将窄间隙模块结构应用于水煤气移位反应。

Abstract - Suppes - 0001518Vessels and tanks interconnected with pipes are the current construction paradigm in the chemical process industries. For many applications, similar processing can be achieved by narrow-gap architecture scaled up through the use of banks and modules. The PI plans to look at the narrow-gap approach, which is a massively parallel and modular approach to chemical process construction. For this method, unit operations, including reactors, separation processes, mixing, and electrochemical processes are designed in architectures comprised of plates and gaskets fastened face-to-face. Mass transport for a unit operation or between unit operations is distributed evenly through the plates and generally in a direction normal to the faces of the plates. Multiple design degrees of freedom are set by the architecture of the plates and gaskets - resolving flow patterns, residence time distributions, heat transfer processes, and disengaging processes.The goals of this Small Grant for Exploratory Research program are to: (1) construct a working module demonstrating the concept and illustrating the narrow-gap approach as superior to traditional process architecture, and (2) evaluate and develop processes unique to the architecture such as porous-media based plug flow reactors, membrane integration, and fluid flow networking. To demonstrate the method, the narrow-gap module architecture will be applied to the water-gas shift reaction.
