Traditional vapor-compression refrigeration relies on hydrofluorocarbons (HFCs) as refrigerant fluids — a class of compounds with global-warming potentials (GWP) thousands of times higher than that of CO2. A new approach from scientists at Lawrence Berkeley National Laboratory (LBL; Berkeley, Calif.;…
Separating recyclables from our trash has become commonplace for many of us. What can be recycled and how it is collected, however, varies quite a bit by location. My town, for example, accepts plastics #1 (polyethylene terephthalate; PET), #2 (high-density…
Discovering new catalysts and materials for specific applications can be a tedious and time-consuming process involving labor-intensive tests and expensive samples. Technology developed by Mattiq (Skokie, Ill.; www.mattiq.com) enables the “printing” of tens of thousands of tiny material samples onto…
With global temperatures likely to rise beyond the 1.5°C target set by climate experts, negative emissions technologies — most notably direct air capture (DAC) — become increasingly important for addressing CO2 already in the atmosphere. A new DAC approach is…
Modern solutions help processors achieve water-related goals in a more proactive, cost-effective way Although water reuse and recycling began as a necessity in regions where water scarcity was a significant challenge, the increasing cost of water coupled with aggressive sustainability…
This year’s Weftec technical exhibition and conference (www.weftec.org) is taking place Sept. 30–Oct. 4 in Chicago, Ill. The event will highlight the newest technologies to address water- and wastewater-treatment challenges. This preview highlights a small selection of Weftec exhibitors.
Facilities can reduce emissions without major capital projects. Here are some practical ideas showing where to start People working in the air-pollution control industry used to boast that you can remove everything from fluegas except carbon dioxide, and it remains…
The products of the chlor-alkali process continue to be essential for many purposes across the global value chain. Modern chlor-alkali technologies can vastly improve upon the safety and environmental performance of legacy systems The chlor-alkali production process is one of…
From September 26–28, the bulk solids and conveying technology industry will gather at the Nuremberg, Germany exhibition halls. Powtech 2023 is a leading trade fair for processing and bulk-solids technology, with exhibitors from a number of sectors of the chemical…
On-point configuration for all requirements With the new Flender One platform, this company’s engineers have developed the world’s narrowest gear-ratio range, with 103 stages between 1 and 7.1 per size for applications that require particularly precise speed, such as pumps…
