The production and processing of cathode active materials (CAM) are among the largest contributors to the cost of lithium-ion battery manufacturing. Typical CAM manufacture involves multiple, multi-phase steps in a co-precipitation process that requires a large amount of water and…
Hydrogen fuel cells and electrolyzers will be crucial technologies as the global energy transition progresses. However, both devices are often hampered by issues with durability and material costs — mainly associated with their membrane elements — which have slowed their…
Bipolar plates (BPPs) are a key component in electrolyzers and fuel cells. BPPs include two key components: the membrane electrode assembly (MEA), in a fuel-cell system; and the catalyst-coated membrane (CCM), in an electrolyzer. In a fuel-cell stack, for example,…
Hydrogen chloride is an important byproduct of the chemical industry, with over 9-million ton/yr generated by industrial chlorination processes, such as the production of chloromethanes and polymers (polyurethanes and polycarbonates). Although HCl can be easily recovered by gas scrubbing with…
There have been several recent announcements regarding regulatory changes that affect the chemical process industries (CPI). One of the latest is a set of final rules announced on April 9 by the U.S. Environmental Protection Agency (EPA; www.epa.gov) that significantly…
Nanocellular graphene (NCG) is a specialized form of graphene that achieves a large specific surface area by stacking multiple layers of graphene and controlling its internal structure with a nanoscale cellular morphology. Although the material has the potential to improve…
Membranes are widely used in a variety of industrial separation processes, but the polymeric materials that make up many membranes are not durable enough to handle extreme conditions, such as processes with low pH or hazardous-metal content. Membrion, Inc. (Seattle,…
Steam-heated storage tanks are critical to manufacturing processes, and prioritizing reliability in tank-system design and operations can mitigate unwanted issues Storage tanks are essential to the chemical process industries (CPI), and they require significant capital investment to ensure optimal installation…
Trends related to the energy transition are shifting global demand for refined products and affecting feedstock slates, forcing petroleum refiners to embrace adaptation and flexibility Demand for fossil fuels has remained strong in the years after the COVID-19 pandemic, but…
Plant Watch Celanese expands production capacities for acetic acid and VAE April 9, 2024 — Celanese Corp. (Dallas, Tex.; www.celanese.com) started up a new production unit for vinyl acetate ethylene (VAE) in Nanjing, China and completed several downstream debottlenecking projects…
