A Methodology to Integrate Closed‐Cycle Heat Pumps into Batch Distillation Columns
Chemie Ingenieur Technik, EarlyView.Batch distillation often cannot use vapor recompression due to contamination risks in food and pharma. This study proposes a design for integrating closed‐loop heat pumps using natural fluids. Results show significant energy savings, offering a sustainable alternative to traditional setups.
