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.

Impact of Distillation Column Design on Potential for the Integration of Mechanical Vapor Recompression

Chemie Ingenieur Technik, EarlyView.
Mechanical vapor recompression integration in distillation is analyzed, focusing on feed preheating and column pressure drop. Binary methanol–water and benzene–toluene separations are studied to identify optimal designs, which are further assessed in a bioethanol vacuum distillation sequence regarding energetic, ecological, and economic performance ...

Preliminary Numerical Evaluation of Directly Heated Structured Packings to be Used for Separation Processes

Chemie Ingenieur Technik, EarlyView.
In terms of electrification, directly heated structured packings are a viable option. They offer the advantage of providing energy where it is required, thereby positively impacting the separation process and helping to minimize heat loss. Using CO2 desorption from aqueous MEA solution as an exemplary process, different heating strategies are compared.
