The industrial production of aluminum involves electrolysis of alumina (Al2O3) in molten cryolite, a mineral used as a solvent for the aluminum oxide raw material. Over time, the cryolite accumulates impurities, such as sodium, lithium and potassium ions, which degrade…
KSE 3.0 safety valves (photo) replace their predecessor’s polytetrafluoroethylene (PTFE) housing lining with PFA copolymer, which is thermoplastic processable and transparent, facilitating visual quality inspection of the lining. For a seamless replacement, the leg dimensions of the new PFA-lined safety…
Effective measurement of corrosion on process equipment and plant structures offers several benefits to plant operators. These include providing early warnings about damaging process conditions that could lead to corrosion-induced failures, establishing correlations between changes in process parameters and their…
Plant Watch Saint-Gobain Ceramics to construct catalyst carriers plant in New York March 11, 2025 — Saint-Gobain S.A. (Courbevoie, France; www.saint-gobain.com), through its subsidiary Saint-Gobain NorPro, intends to build a new manufacturing facility in Wheatfield, N.Y. With an investment of…
Aluminum smelting operations require molten cryolite, also commonly called bath, to serve as the electrolyte and dissolve alumina. A typical smelter produces excess bath over time, and there are few markets for reuse or recycle of this material, especially as…
The 8271 CMP miniature pressure transmitter (photo) is designed with small and rugged construction that enables integration into processes where space is limited. It withstands harsh environments, vibrations and potential physical impacts, ensuring longevity. An optional five-fold overpressure resistance enhances…
Coveralls for chemical and fire protection This company’s recently launched Tychem® 6000 SFR is a lightweight, hooded garment (photo) designed to help protect people working in challenging environments against multiple chemical and flash-fire hazards. Tychem garments may be suitable for…
The new CablePro tubular drag conveyor (photo) is designed with components that offer chemical compatibility, including corrosion-resistant coatings and polished stainless-steel tubing. It is equipped with self-lubricating disks, which are injection-molded directly onto a pre-stretched, oil-lubricated stainless-steel braided cable with…
Enhanced measurement capabilities offer more reliable control to boost quality, reduce waste and ensure safety As optimization, sustainability and safety initiatives continue to be a driving force in the chemical process industries (CPI), accurate, responsive and reliable temperature measurements are…
