Stirred tanks are common throughout the chemical process industries (CPI), used as batch reactors and continuous-flow reactors, as well as for physical processing of product formulations in which no chemical reaction is occurring. In all cases, fluid mixing — in…
Understanding both the limitations of process simulations and the assessments that can be performed to verify modeling results are important in the design and development of technical processes in many industries Chemical engineers routinely use process simulation software for design,…
An advanced membrane-chamber filter press improved material recovery and operating efficiency while lowering operating costs at a facility for the recycling of construction materials In today’s world, where resource conservation and sustainable practices are more important than ever, the RCO…
As connected devices and systems have become more advanced, engineers in turn have become savvier about the realities of a digitally connected enterprise, especially with regard to securing their operational technology (OT) systems. Even with globally increasing cybersecurity awareness, however,…
Combining microscopy and machine-learning techniques leads to faster, more precise analyses of critical coating materials When the SR-71 Blackbird aircraft was designed to soar at three times the speed of sound, engineers faced an extreme challenge: managing the heat generated…
A novel crystallizer has shown promise in lowering costs for direct-air capture (DAC) of CO2 emissions. In recent work published in Nature Chemical Engineering, a research team from the University of Toronto; www.utoronto.ca), led by mechanical and industrial engineering professor…
Black mass is the powdered material resulting from shredding end-of-life lithium-ion vehicle batteries. For effective recycling, lithium must be efficiently separated from this material, but conventional methods, such as smelting at high temperatures or dissolving in strong acids, require large…
Several situations, including when takeaway capacity is limited at remote oil-well sites, result in methane flaring. To avoid wasting that resource, several strategies have been explored to convert methane onsite into commercially useful liquid chemicals. One of the approaches is…
A first-of-its-kind demonstration unit is showcasing hydrogen liquefaction using magnetocaloric cooling, a process that demands much lower energy consumption than conventional methods used in industry. A joint venture between Magnotherm Solutions GmbH (Darmstadt, Germany; www.magnotherm.com) and Helmholtz-Zentrum Dresden-Rossendorf (HZDR; Dresden,…
A unique class of chlorine-resistant membranes is set to enhance the performance of processes requiring zero liquid discharge. NALA Membranes (Morrisville, N.C.; www.nalmembranes.com) has developed highly stable and durable membranes based on sulfonated polysulfone materials that overcome many of the…
