👉 A swap fluid, also known as an exchangeable fluid or a transfer medium, is a substance used in various industrial and scientific processes to facilitate the exchange of components between different chemical species or phases. This fluid typically consists of a solvent or a mixture that can dissolve and transport various elements or compounds, allowing them to be interchanged without altering their chemical identities. Swap fluids are crucial in processes like gas absorption, liquid-liquid extraction, and catalytic reactions, where they help optimize efficiency, reduce waste, and enable the recovery or reuse of valuable materials.
