3D‐Printed Coil Immobilized Enzyme Reactors for Laccase Biocatalysis in Single‐ and Two‐Phase Flow

Chemie Ingenieur Technik, EarlyView.
Development of 3D‐printed immobilized enzyme reactors functionalized with laccase for continuous‐flow biocatalysis. Surface coupling and reactor design enhanced stability and mass transfer, enabling efficient and reusable biocatalytic processes.

Process Modeling for Propylene Polymerization to Transfer Reaction Kinetics From Lab to Plant

Chemie Ingenieur Technik, EarlyView.
The modeling approach combines an industrial model for a fourth‐generation Ziegler–Natta catalyst with lab‐scale derived kinetics of a novel fifth‐generation catalyst. By transferring intrinsic kinetics across scales, polypropylene production can be predicted. Accurate melt flow rate prediction is only obtained with an additional adjustment.

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.

Waste activated sludge high‐rate treatment of septage: Biodegradability studies and contact phase trials towards a cleaner environment

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The waste activated sludge high‐rate (WASHR) process, developed in our previous study, is used for septic wastewater treatment. This high‐rate contact stabilization pre‐treatment uses typical waste streams found in wastewater treatment plants to reduce a portion of the loadings on the main treatment trains.

Application of influence diagrams to multi‐objective allocation of firefighting resources in process plants

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.
