Predictable plant-based production of complex biomolecules
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…
This electrolysis cell produces high-purity iron
Processing iron ore is the most carbon-intensive step in the steelmaking process, often using coal as an energy source. A new technology, called Molten Oxide Electrolysis (MOE) aims to decarbonize the iron-ore process through electrification. “In the MOE cell, an…
A new approach to refrigeration with no global-warming potential
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.;…
‘Printing’ new catalyst candidates onto a chip
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…
Direct-air capture of CO2 via a liquid-based, low-temperature, thermochemical system
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…
The Changing Face of Water Treatment
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…
Facts At Your Fingertips: Plant Cybersecurity Awareness
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…
Optimizing Fluidized-Bed Drying Processes
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…
Advances in Chlor-Alkali Technologies
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…
Rotary Drum Maintenance
Follow these nine recommendations to establish a strong program for preventive maintenance of rotary drums in drying, cooling and other treatments of bulk solids Maximizing efficiency is increasingly a critical priority for plant managers, leading many to move away from…
