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.

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.

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.

Using Financial and Sustainability Ratios to Map Sectors. An Approach With Compositional Data

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT The article aims to visualize in a single graph Spanish fish and meat processing companies with respect to solvency, energy, waste and water intensity and gender employment gap. These financial, environmental, and social indicators are ratios, which require specific statistical analysis methods.

Analysis and Characterization of Kisspeptin and Its Analogues in Serum and Urine Samples by Liquid Chromatography–High‐Resolution Mass Spectrometry for Doping Control Purposes

Drug Testing and Analysis, EarlyView.
Sensitive LC‐HRMS methods were established for the detection of kisspeptin and its analogues in serum and urine, alongside their analytical and metabolic characterization. Stability studies were conducted in serum, plasma, and urine, highlighting the importance of appropriate sample handling for reliable anti‐doping analysis.

Numerical simulation study on the evolution of the temperature field and frozen wall in fractured rock mass

Deep Underground Science and Engineering, EarlyView.
The evolution of the temperature field and frozen wall under different fracture conditions was examined by an artificial ground freezing‐based thermal‐hydraulic coupled model. It was observed that fracture inclination affects the interaction extent of freezing pipes and fracture, while phase transition extent is the dominant factor for heat transfer in
