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,…
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…
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…
A large selection of ion-exchange resins is available today for a constantly growing variety of applications. In order to choose the appropriate resin for a specific application, it is important to carefully evaluate the range of resin and process properties…
Performance improvements in robotics technologies for manufacturing and energy operations are leading to greater productivity, cost savings and safety improvements In the chemical process industries (CPI), mobile robots, often in conjunction with artificial intelligence (AI) and machine learning (ML), are…
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…
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…
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,…
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…
