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…
Metso Corp. (Helsinki, Finland; www.metso.com) has optimized its existing rotary kiln technology and launched RotarEkiln, an electrically powered, indirectly heated rotary kiln. The electric heating system of the RotarEkiln provides a sustainable alternative to conventional fuel-powered indirect rotary kilns. The…
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…
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…
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…
Modern control technologies and industrial automation strategies can help processors use fluidized-bed dryers to drive competitiveness and profitability The ability of fluidized-bed dryers to achieve exceptional performance and deliver high-quality results in the controlled, gentle and homogeneous drying of wet…
Most plant-based bioprocesses involve growing plants in outdoor fields or greenhouses, but this is hindered by local climates and available space, and typical product yields are very low per plant, especially for natural active molecules used in pharmaceutical and healthcare…
E3 Lithium Ltd. (Calgary, Alta., Canada) announced that commissioning of its Direct Lithium Extraction (DLE) field pilot plant is complete and operations have begun. The commissioning process included connecting all major pieces of equipment to the piping and wiring systems…
