使用含水单乙醇胺（MEA）的CO2捕集过程需要显著的能量消耗。存在各种可能的结构修改，其可以被实施以减少这些能量需求并提高能量效率。然而，由于最佳配置可能包含不同修改的组合，因此有必要采用系统的方法来考虑所有可能性。在这项研究中，一个超结构，包括传统的胺为基础的CO2捕获配置和四种不同类型的结构修改构建在过程模拟器UniSim®。这种上部结构的优化揭示了提供最低能源成本的配置和操作条件，系统地同时考虑了所有可能的修改。这种方法被应用到一个CO2捕获的案例研究，以说明如何建议的建模和优化框架可以有效地调查设计方案，以提高能源效率。
CO2capture processes using aqueous monoethanolamine (MEA) require significant energy expenditure. There are various possible structural modifications which can be implemented to reduce these energy requirements and enhance energy efficiency. However, as the optimal configuration may contain a combination of different modifications a systematic approach is necessary to consider all possibilities. In this study a superstructure including the conventional amine-based CO2capture configuration and four different types of structural modifications is constructed in the process simulator UniSim®. Optimization of this superstructure reveals the configuration and operating conditions giving the minimum energy costs, systematically and simultaneously considering all of the possible modifications included. This methodology is applied to a CO2capture case study to illustrate how the proposed modeling and optimization framework can effectively investigate design options available for improving energy efficiency.
