Learn how Enhanced Coriolis Control (ECC) helps you avoid common measuring errors
Enhanced Coriolis Control (ECC) mitigates the negative impact of high gas content in your measurement of liquids One of the most common reasons for measuring errors in Coriolis mass flowmeters is the measurement of liquids with significant gas…
INEOS Enterprises to sell sulfur dioxide business to Ecovyst
INEOS Enterprises has agreed to sell its shares in INEOS Calabrian, its ultra-pure sulfur dioxide and derivatives business, to Ecovyst Inc. (Malvern, Pa.). INEOS Calabrian operates manufacturing sites in Port Neches, Texas, USA and Timmins, Ontario, Canada. Completion is expected…
GEA launches meVap® family to electrify industrial heat and accelerate decarbonization
In industrial plants, the biggest climate gains are often hidden in plain sight. Behind every evaporation step, every distillation column and every crystallization line lies a constant demand for heat — and with it, a major opportunity to cut emissions.…
Waterless technology uses supercritical CO2 to recycle textile waste
Textile waste is one of the fastest-growing waste streams globally, and there are limited options available to efficiently recycle end-of-life textiles into useful materials. A new recycling approach developed by Renasens (Stockholm, Sweden; www.renasens.com) utilizes supercritical CO2 to recover intact…
Modular, low-cost ammonia-production system is designed for intermittent energy
Ammonia is a critical input for agricultural fertilizers, but NH3 production is plagued by volatile prices, difficult global logistics and high CO2 emissions. A new NH3-production system from the startup TalusAg (Austin, Texas; www.talusag.com) addresses these challenges with a modular…
Molten-salt nuclear reactors take the next step toward industrial deployment
Over decades of experimentation, molten-salt nuclear reactors have been shown to deliver high-temperature heat and extremely efficient electricity at reduced pressures. However, these reactors have yet to make the leap into widespread industrial adoption. Terrestrial Energy Inc. (Charlotte, N.C.; www.terrestrialenergy.com)…
Process for cellulose-derived pigments scales up to hundreds of tons/yr
A process for making pigments from cellulose for use in cosmetics, food and coatings applications has scaled up from a 1-ton/yr pilot unit to a process capable of generating multiple-hundreds of tons per year in a toll-manufacturing setting. The cellulose-derived…
PVC polymer chlorination with LEDs enhances resin stability
Lubrizol (Cleveland, Ohio; www.lubrizol.com) recently began producing chlorinated polyvinyl chloride (CPVC) resin in commercial reactors equipped with light-emitting diodes (LEDs) as the light source, instead of the conventional mercury lamps. The company’s LED reactor technology enhances the thermal stability of…
Low-temperature plasma process supports direct recycling of battery cathodes
Direct battery-recycling methods, such as re-lithiation — where depleted lithium is replenished directly onto cathodes via a solid-state reaction — hold many benefits over indirect methods, such as those relying on hydrometallurgy or pyrometallurgy, where cathodic structures are destroyed in…
Electrochemical-redox process expands recycling potential for LFP batteries
Lithium-iron-phosphate (LFP) batteries offer a compelling combination of performance characteristics for stationary energy storage, including improved safety and longevity, when compared to other lithium battery chemistries, such as nickel- and cobalt-based formulations. However, there are limited recycling pathways dedicated to…
