Clathrate-Based Recovery of Sulfuric Acid from Spent Acid

Recently, the applications of hydrate phenomena in industrial processes have been increasing. A clathrate or is a solid, ice-like compound that forms when water/guest mixed under certain conditions. Hydrogen water molecules bond with guest to form crystal lattice. Different guests can Clathrate (e.g., gases liquids). Dilute Sulfuric acid usually generated at different plants, and these dilute acids are considered waste because they cannot be reused again. Many treatment handle this environmental problem, like electrochemistry, precipitation, adsorption, membrane filtration, ion exchange. Although such significant operational advantages, their disadvantage many high costs process products toxic pollutants. This work utilized experiments re-concentrate sulfuric acid. The selected was Cyclopentane. Each experiment s consists mixture Cyclopentane acids. volume ratios were (6:1, 4: 1, 3:1, 2:1) initial concentrations (12.5%, 10%, 7.5%, 5%, 2.5%) It found method effective maximum efficiency 94% ratio /cyclopentane (6:1) 12.5% concentration. concluded increase leads increasing removal while reducing yield percentage enriched Factor.
