Summary: This study evaluated the recovery of caustic from textile mercerization wastewaters using evaporation and membrane filtration processes and compared their environmental and economic performance. The results showed that membrane filtration had better environmental performance than evaporation. However, combining membrane filtration with evaporation reduced the environmental benefits of membrane filtration alone. In terms of cost-effectiveness, evaporation was found to be more cost-effective than membrane filtration. Therefore, evaporation may be preferred when concentrated caustic solution is required, while membrane filtration can be preferred when dilute caustic solution is sufficient or when the recovered dilute caustic needs to be mixed with new concentrated solution for further use in production processes.

Summary: In the past decade, there has been a growing interest in studying energy systems for the combined management of power vectors. Most of the published works focus on finding the optimal design and operations of Multi Energy Systems (MES). However, for newcomers to this field, understanding how to achieve the desired optimization details while controlling computational expenses can be challenging and time-consuming. This paper presents a novel approach to analyzing the existing literature on MES, with the aim of guiding practical development of MES optimization. Through the discussion of six case studies, the authors provide a mathematical formulation as a reference for building the model and emphasize the impact of different aspects on the problem nature and solver selection. In addition, the paper also discusses the different approaches used in the literature for incorporating thermal networks and storage in the optimization of multi-energy systems.
