Honeywell doubles production capacity for Solstice ze in Baton Rouge
Honeywell International Inc. (Charlotte, N.C.) announced its Baton Rouge, LA., facility has doubled production capacity of Honeywell Solstice ze (HFO-1234ze), an ultra-low-global-warming-potential (GWP) and energy-efficient solution compared to other current technologies. Solstice ze is used in foam insulation, as an aerosol…
DSM begins construction of new manufacturing plant in Scotland
Royal DSM N.V. (Herleen, the Netherlands) began construction of a new manufacturing facility at its site in Dalry, Scotland. The plant will significantly increase global production of Bovaer, DSM’s unique methane-reducing feed additive for cattle. In an official groundbreaking ceremony…

Elementis plc (London) announced that it has agreed to sell its Chromium business to Yildirim Group for an enterprise value of $170 million. The transaction includes the transfer of environmental liabilities of $35 million and other liabilities of $8m, with…
Facts At Your Fingertips: Liquid-Liquid Extraction Basics
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…
Simultaneous Pump and System Sizing
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…
Iridium-free electrolysis demonstrated for stable hydrogen production
The necessity for precious metals, such as iridium, in water-splitting catalysts is a major challenge in the feasibility of large-scale production of hydrogen using electrolysis. Now, a team of researchers from Rice University (Houston; www.rice.edu) has developed a mechanism for…
Recycling halogens electrochemically
Next April, a six-year, €4-million project will begin that aims to develop an electrochemical process to recover halogens (chlorine, bromine and fluorine) from waste products. Funded as part of the CZS Breakthrough program of the Carl Zeiss Foundation (CZS; Heidenheim…
Supercritical extraction drives ‘molecular washing machine’ for plastic waste
A new recycling process has been developed for scrap polypropylene (PP), a waste stream that is currently underserved by many plastics-recycling facilities. The process, developed by PureCycle (Orlando, Fla.; www.purecycle.com), aims to “wash the plastic molecules” using a series of…
Making more from mining water with electrowinning
A new electrowinning process is being field-trialed at the Prieska copper-zinc mine operated by Orion Minerals Ltd. (Melbourne, Australia; www.orionminerals.com.au) in South Africa, which will enable the production of valuable products, including calcium, magnesium, iron and others, from contaminated mine…
Pump Troubleshooting Using Video Analysis
By allowing maintenance professionals to visualize vibration on entire pump systems, video vibration analysis and motion magnification can help to rapidly diagnose vibration issues Video vibration analysis, and motion magnification in particular, is democratizing complex system-level vibration testing by making…
