Granular activated carbon (GAC) can be used to remove polyfluoroalkyl substances (PFAS) from groundwater and drinking water, but current methods to regenerate spent GAC are costly and require high temperatures of greater than 1,000°C. A team of scientists at Battelle…
The NT3100sc and the NT3200sc ultraviolet (UV) nitrate and nitrite sensors (photo) are designed with enhanced accuracy and a lower limit of detection at 0.02 mg/L. Leveraging reagent-free UV absorbance technology, NT3 Series sensors are equipped to meet a wide…
This year marks Chemical Engineering’s 120th anniversary. At this extraordinary milestone, I paused to look into the history of the publication and its evolution to where we are now. The magazine evolved, changing its name to reflect changes and combinations…
When scaling up new processes involving complex feedstocks, such as biomass, well-defined mixing is key. Guidelines presented here will help to efficiently move biomass hydrogenation reactions from the laboratory to commercial-scale operations One of the most promising pathways to biomass-based,…
Liberty Steel UK (LSUK; London; www.libertysteelgroup.com) has completed trials of ecoke — a sustainable new raw material that can replace anthracite, the main source of charge carbon used in the electric-arc furnace (EAF) of steelmaking, and reduce steel’s carbon footprint…
As dust collection becomes an integral part of chemical processes, monitoring and other technologies promote efficiency and performance Dust control has always been important in the chemical process industries (CPI) due to the often toxic and combustible nature of the…
In late October, Metso Outotec Corp. (Helsinki, Finland; www.mogroup.com) introduced the DRI (direct reduced iron) Smelting Furnace to substitute blast furnaces used in iron- and steelmaking. The furnace was developed to tolerate high-slag volumes, which are problematic for a conventional…
Flow analysis can aid in simultaneously sizing pumps and associated piping systems. The concurrent sizing can reduce wasted energy and improve pump reliability In the chemical process industries (CPI), a variety of incredible process-simulation tools are available to provide greater…
Liquid-liquid extraction (LLE) is a separation technique that exploits differences in the relative solubility of compounds of interest (the solute) in two immiscible liquids — most often an aqueous phase and an organic solvent. This one-page reference reviews basic information…
A new level detector for multiphase applications Multiphase level measurements exist throughout chemical process industries (CPI). They are especially significant in the oil-and-gas and petrochemical sectors due to the value derived from effectively separating water and hydrocarbons. While level instrumentation…
