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…
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…
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.;…
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 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…
The expanding use of digitalization tools at chemical process industries (CPI) facilities, coupled with the ongoing convergence of operational technology (OT) systems with traditional computer information technology (IT) systems, has increased plant cybersecurity risks. All plant personnel play a role…
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…
Bioprocessing facilities can achieve compliance, prevent downstream contamination and increase water reuse by using advanced oxidation processes Wastewater generated from bioprocessing facilities is heavily regulated in the U.S. by the Environmental Protection Agency (EPA; Washington, D.C.; www.epa.gov) and various state…
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…
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.
