Chemistry – A European Journal, EarlyView.It is demonstrated that the photoinduced cycloreversion of a methoxynaphthylquadricyclane in the presence of suitable photocatalysts gives quantitatively the corresponding norbornadiene. As this photochromic norbornadiene‐quadricyclane cycle has favorable properties for light energy conversion, this method provides a useful tool for the targeted ...

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.

Potential Analysis of On‐Site Oxygen and Ozone Production for Wastewater Treatment Plants
Chemie Ingenieur Technik, EarlyView.The potential of a power‐to‐gas process focusing on the oxygen stream to cover an upcoming demand of ozone at German wastewater treatment plants is analyzed. Economic and ecological parameters are compared to the conventional production of hydrogen and oxygen. Powered by on‐site produced wind energy, the process is deemed beneficial.

The Canadian Journal of Chemical Engineering, EarlyView.Abstract Identification of firefighting strategies (i.e., which endangered units to suppress or cool first) in chemical and process plants falls under the domain of multi‐objective decision‐making (MODM), where not only the safety and integrity of the affected process plant but also the safety of on‐site and off‐site vulnerable targets matter.

The Canadian Journal of Chemical Engineering, EarlyView.The contaminant removal performance of a conventional coagulant, alum, and alternative coagulants, aluminium chlorohydrate (ACH) and ACH + pDADMC, are compared in challenging wastewater treatment conditions (pH >7.8). The interactions of each coagulant with a negatively charged surface are depicted based on quartz crystal microbalance with dissipation ...

The Canadian Journal of Chemical Engineering, EarlyView.Left: Desulphurization method application. Right: Novel desulphurization method. Abstract The presence of hydrogen sulphide (H2S) in biogas poses significant environmental and operational challenges due to its corrosive and toxic properties. Thus, this study aimed to develop a dual‐function desulphurization system using a cation exchange resin (CIER ...
