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.

Development of a Mechanically Regenerating Desublimator for Freeze‐Drying Systems in the Food Industry

Chemie Ingenieur Technik, EarlyView.
Thermal defrosting limits desublimator efficiency in freeze‐drying. This review and case study compares thermal versus mechanical regeneration, links frost properties and external heat transfer to energy demand, and summarizes pilot‐scale scraping results enabling single‐unit, continuous lyophilization.

Matching Heat Pump Configurations and Process Parameters for Cost‐Minimal Heat‐Integrated CO2 Capturing Process

Chemie Ingenieur Technik, EarlyView.
In a CO2 absorption process, it is investigated whether the adjustment of operating parameters facilitates the integration of different closed heat pump cycles considering various refrigerants. The influence of different integration concepts and electricity prices are investigated by means of resulting total annual costs.

Valorization of Yacon (Smallanthus sonchifolius) peel for peroxidase production and its immobilization on alginate beads for 2,4‐dichlorophenol bioconversion

The Canadian Journal of Chemical Engineering, EarlyView.
Sodium alginate was modified with EDC/NHS for the immobilization of Yacon peel peroxidase, resulting in a novel biocatalyst for the oxidation of 2,4‐dichlorophenol. Abstract Yacon (Smallanthus sonchifolius) roots are emerging as an alternative source of peroxidase. This study aimed to extract, immobilize, and characterize the peroxidase from Yacon peel,

Performance comparison of pressure swing adsorption and amine‐based absorption for synthesis gas purification

The Canadian Journal of Chemical Engineering, EarlyView.
Comparison of PSA and amine‐based absorption for syngas purification shows that PSA offers lower energy intensity, global warming potential, and minimum selling price, making it a more sustainable option. However, absorption achieves higher syngas purity. A GREENSCOPE‐based multi‐criteria assessment guides optimal process selection.
