Abstract

Increasing demands for sustainable and distributed freshwater sources drive the exploration of water extraction from ambient air. This study presents a comprehensive computational approach for optimizing unit harvesting cost of the adsorption-based atmospheric water extraction (AWE) systems. There are three objectives (i) assessing the impact of climate variability: utilizing k-means clustering, utilizing climate data in different regions to explore the effects of ambient conditions in dry-hot (California), humid-hot (Florida), and dry-cold (Wyoming) regions, resulting in a preference for harvesting under humid-hot conditions. (ii) performing kinetic analysis: The derived kinetic model connects climate variability to operational time and regeneration temperature, critical process design variables. (iii) assessing adsorption materials: three materials (MIL-100 (Fe), MOF-303, and ZJNU-30) were assessed revealing the impact of variations in maximum capacity and isotherm shape on performance and cost. The optimization algorithm uses a two stage stochastic programming approach to account for climate variability and enables an optimization that balances the capital and operating costs across a range of temperature and humidity conditions.

用于大气水提取的金属有机框架：气候多变性下的动力学分析和随机编程

对可持续和分布式淡水资源日益增长的需求推动了对从环境空气中提取水的探索。本研究提出了一种综合计算方法，用于优化基于吸附的大气取水（AWE）系统的单位取水成本。研究有三个目标 (i) 评估气候多变性的影响：利用 k-means 聚类，利用不同地区的气候数据，探索干热（加利福尼亚州）、湿热（佛罗里达州）和干冷（怀俄明州）地区环境条件的影响，从而得出在湿热条件下采水的偏好。(ii) 进行动力学分析：推导出的动力学模型将气候变异与操作时间和再生温度这些关键的工艺设计变量联系起来。(iii) 评估吸附材料：评估了三种材料（MIL-100（铁）、MOF-303 和 ZJNU-30），揭示了最大容量和等温线形状的变化对性能和成本的影响。优化算法采用了两阶段随机编程方法，以考虑气候的可变性，并实现了在一系列温度和湿度条件下平衡资本和运营成本的优化。

期刊介绍： The Journal of Cleaner Production is an international, transdisciplinary journal that addresses and discusses theoretical and practical Cleaner Production, Environmental, and Sustainability issues. It aims to help societies become more sustainable by focusing on the concept of 'Cleaner Production', which aims at preventing waste production and increasing efficiencies in energy, water, resources, and human capital use. The journal serves as a platform for corporations, governments, education institutions, regions, and societies to engage in discussions and research related to Cleaner Production, environmental, and sustainability practices.
