Despite its advantages, solvent recovery presents several challenges:
- Purity Requirements: High-purity solvents are often required for reuse, necessitating efficient separation techniques. - Energy Consumption: Methods like distillation can be energy-intensive, impacting the overall process economics. - Complex Mixtures: The presence of multiple solvents and reaction by-products can complicate the recovery process. - Degradation Products: Over time, solvents can degrade, forming impurities that must be removed to maintain solvent efficacy.
