Despite its benefits, solvent regeneration comes with several challenges: - Energy Consumption: Processes like distillation require significant amounts of energy, making them costly and less environmentally friendly. - Complexity of Impurities: Some impurities are chemically similar to the solvent, making them difficult to remove. - Degradation of Solvent: Over time, solvents can degrade, losing their effectiveness. Regeneration processes must ensure that the solvent retains its original properties.
