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.

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.

Experimental methods in chemical engineering: Atomic absorption spectrometry—AAS

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Elements absorb electromagnetic radiation (light) of a specific wavelength in proportion to the number of atoms in its path. As the atoms absorb this light energy, electrons rise from the ground state to an excited state. In atomic absorption spectrometry (AAS), high temperatures produce clouds of atoms from the sample (atomization) and ...
