Evaluation of Solvent Recovery Options for Economic Feasibility through a Superstructure-Based Optimization Framework

“…Organic solvent use can account for as much as 90% of the process by mass and often disposed of after one cycle because of purity concerns, which is not a sustainable practice. − A large quantity of solvent waste and emission can occur as a result. These events are caused by inefficient mixing, synthesis pathways, insufficient reaction time, inappropriate technologies, quality of raw materials, inaccurate measurements, and control anomalies. , As a response to the growing concern for chemical waste and environmental impacts, the global environmental initiative has given rise to legislation and policies put forth by regulatory agencies from around the world. ,− Additional work is in progress by several researchers to address environmental management, , sustainability indicators, − controllability, , and multistakeholder decision-making for the greater benefit of society, thus supporting the global environmental initiative and the United Nations Sustainable Development Goals of responsible consumption and production as well as climate action. , This study proposes an optimization framework to address the economic challenges in implementing waste recovery in chemical processes.…”
