Meeting climate-change goals requires steep reductions in greenhouse-gas emissions from existing power plants and hard-to-abate industry operations. However, the energy required to release captured CO2 from sorbent material is a challenge for the economic viability of these efforts. Also, retrofitting…
A next-generation absorbent material with a high affinity for short- and long-chain per- and polyfluoroalkyl substances (PFAS) has recently been granted a patent in the U.S. Developed by Puraffinity Ltd. (London, U.K.; www.puraffinity.com), the material is bottom-up-designed, beginning with a…
This flowmeter is designed for demanding applications Measuring volumetric flow accurately and reliably is difficult for applications where the process liquid is highly viscous, extremely abrasive, prone to plugging, at high temperature, or a combination of these conditions. In applications…
Innovation, intelligence and automation increase precision in weighing equipment for chemical processors Accurate weighing and dosing are critical to the success of any chemical process, because they ensure product quality, safety and resource optimization. Fortunately, innovative technologies, intelligence and automation…
Dry reforming of methane (DRM), in which carbon dioxide and methane are combined to form synthesis gas (H2 and CO), is an attractive route to making syngas because it does not require consumption of water and does not produce CO2…
Electrochemically converting carbon dioxide into useful chemicals or fuels is a promising CO2-utilization strategy, but scaling up the process is a challenge. One reason is that the gas-diffusion electrodes (GDEs) used to facilitate contact between gaseous CO2, solid catalyst and…
The use of fixed gas detectors can play a crucial role in mitigating the environmental impact of hydrogen leakage and help protect workers in the hydrogen value chain Governments, industry sectors and companies seeking sustainable energy sources to reduce greenhouse…
Powerful permanent magnets Permanent magnets — materials that create their own persistent magnetic field — are frequently used in most types of electronics, turbines, engines and motors. Currently, nearly all powerful permanent magnets require rare-earth elements (REEs), such as neodymium…
Digitalization can help ethylene producers to flexibly respond to economic uncertainties and assess available options based on their existing infrastructure and priorities Post-pandemic, olefin and polyolefin producers have been faced with regional and global economic headwinds. Inflation, energy security, rising…
Weeping and flooding phenomena set the vapor velocity in industrial distillation columns. Presented here are procedures for calculating flooding and weeping velocities in a four-pass sieve-tray column In industrial distillation, the term “weeping” is primarily used when the liquid in…
