A platform technology for low-carbon cement makes progress
Two recent developments at Queens Carbon Inc. (Pine Brook, N.J.; www.queenscarbon.com), a spinoff company from Rutgers University (New Brunswick, N.J.; www.rutgers.edu), illustrate the potential for reducing the high carbon-dioxide emissions that result from cement and concrete production. Both are results…
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,…
Air Classification of Powdered Materials
Air classification of powdered materials offers a way to control particle size distribution in solids-handling operations. Information on key performance metrics and operating practices of size classification equipment is presented here The handling and processing of solid particulate materials are…
Micro-hydropower systems produce renewable electricity inside pipelines
A first-of-its-kind energy-recovery system harnesses the energy of water flow and pressure in pipelines to produce renewable energy. The patented HydroXS unit, developed by InPipe Energy, Inc. (Portland, Ore.; www.inpipeenergy.com) in collaboration with Grundfos Corp. (Brookshire, Tex.; www.grundfos.com/us), is a…
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…
Carbon dioxide removal combined with desalination
Most existing carbon-dioxide removal (CDR) approaches have focused on air, but the volumetric concentration of dissolved inorganic CO2 in surface water is much higher (150X) than its concentration in the atmosphere. Removing CO2 from water could prove to be a…
Show Preview: Powtech Technopharm
The Powtech Technopharm exhibition (Sept. 23–25; Nuremberg, Germany) highlights all types of technologies for processing powders, solids and liquids. This year’s event boasts an exhibit hall and technical forums, all supporting interdisciplinary dialogues and hands-on technology demonstrations. The following are…
New reactor supports organic-assisted electrolysis for green hydrogen
The production of “green” hydrogen via electrolysis is seen as a key decarbonization pathway for certain industry sectors, but its efficiency can be hampered by a number of factors, including the accumulation of gas bubbles on electrode surfaces within electrolyzers…
Process Analytical Technology and the Role of Raman Spectroscopy
Process analytical technology (PAT) approaches allow continuous monitoring and real-time control of processes. Among the key monitoring technologies is Raman spectroscopy, which offers inline measurement that can reduce personnel time and sampling complexity The chemical industry faces new challenges with…
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…
