- 요약This dissertation addresses the need for improved industrial membrane process modeling and simulation by developing a general framework that considers complex mixture coupling. As our society shifts from everyday products stemming from distillation-based fossil-fuel refineries, to those same products made by means of bio-refineries; utilizing novel separation technologies such as membranes and complex mixtures will be ever more prevalent. A complex mixture refers to either a liquid or gas stream with no single majority component and usually gives rise to mixture interactions (thermodynamic or diffusional coupling) between species. Membranes are used for complex mixture separations in many applications, including water purification, carbon capture, hydrogen separation, olefin/paraffin separation, benzene derivative concentration, and membrane reactor systems. Currently, overall membrane process modeling is heavily reliant on simple models that do not consider complex mixture interactions. In addition, numerical algorithms for simulating membrane performance using a rigorous modeling framework are inefficient and unreliable for systems with many permeants or strong thermodynamic/diffusional coupling. Moreover, membrane thermodynamic and diffusional modeling capabilities are still lacking for transport predictions based on parameters fit from minimal experimental data. Consequently, a general-purpose membrane simulation method with sufficient accuracy, robustness, and efficiency to be included in process flowsheet simulation environments is non-existent. Therefore, there is a critical need for improved numerical algorithms and modeling capabilities for industrial membrane processes involving complex mixtures.To address this need, the overall objective of this work is to develop new theory and algorithms for modeling and simulating industrial membrane modules. Such theory and algorithms must be applicable to any complex mixture, membrane material, and module geometry for integration into overall process flowsheet simulation. This dissertation will start by working with the most logical aspect that is microscopic (local) membrane transport. For the detailed contribution, chapter 2 presents improved numerical methods to solve complex mixture local membrane transport using a Maxwell-Stefan model. For membrane modeling, the most significant challenges have to do with accurate thermodynamic and diffusional predictions that require no multicomponent mixture parameterization (i.e. models with parameters that are fit based solely on pure component data to minimize the number of experiments required). To find the contributions that work towards this goal, chapter 3 presents novel sorption and diffusion models. Additionally, a more compact version of the Flory-Huggins sorption model is presented to enable simulation of complex mixtures with hundreds of components. Then, chapter 4 presents a software package of our contributions for pressure-based industrial membrane processes for use by practicing chemical engineers within process simulation environments. Finally, chapter 5 provides a base case nutrient recovery scenario, simulation framework, preliminary control strategies, preliminary process designs, and a working unit operation code of electrified industrial membranes for nutrient recovery from wastewater treatment plant and concentrated animal farming operation streams. Overall, this work has resulted in novel algorithms, modeling capabilities, and a software package for industrial membrane process simulation. In addition to that, contributions towards electrified industrial membrane processes are presented. Moving forward, the membrane design process involving complex mixtures can compete with the seamless design process of traditional energy or chemically intensive separations such as distillation, extraction, air stripping, or crystallization. Overall, this will enable deployment of complex mixture membrane processes (i.e. more energy efficient and smaller chemical processes). This will benefit society by reducing our environmental footprint, and allow for design of intensified chemical systems.
