Novel reactor addresses limitations of pyrolysis for plastics recycling

Pyrolysis has received much attention as a technology capable of breaking down waste plastics in recycling processes, but existing pyrolysis approaches often give rise to products with broad molar mass distributions and poor yields. Catalysts can improve yield and selectivity,…

Editor’s page: Welcome to Chemical Engineering

This month’s column gives a brief overview of the Chemical Engineering brand. While long-term readers need no introduction to the magazine, newer readers might be interested in the history of the magazine and what we cover. Perhaps even long-term readers…

Switchable solvent supports freshwater extraction from hypersaline brine

Extremely high-salinity water streams present difficulties for many types of processing equipment, such as membranes and filters, and most commercial treatment methods involve thermal evaporators or crystallization, which are energy-intensive and require special anti-corrosion materials. A new membrane-less, non-evaporative process…

Valves for use in Sanitary Processes and High-Purity Applications

Sanitary valves are essential for applications that demand product purity, process integrity and regulatory compliance. This article discusses valve types, working principles and components, and provides considerations for selection and specification Sanitary valves are essential components for applications in the…
