Particle size and shape, as well as particle size distribution (PSD) are key determinants of bulk solids behavior [1–4]. A particle can be defined as a single unit of material having discrete physical boundaries that define its size. Particle science…
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…
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…
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…
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…
RO Membranes Toray Industries, Inc. (Tokyo, Japan; www.toray.com) has developed a highly durable reverse osmosis (RO) membrane that is said to offer double the resistance to cleaning chemicals of conventional counterparts. This reduces performance degradation from membrane wear and simplifies…
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…
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,…
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,…
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…
