Facts At Your Fingertips: Determining RTD in Non-ideal CSTR Reactors

In continuous processes, the properties and quality of the products depend on the residence time of different feed substances, and feed materials may not spend the same amount of time in a reactor. When designing equipment for continuous processes, it…

Dispersing Powders into Liquids: The Role of Vacuum in Wetting

Effectively dispersing powders into liquids can be a challenge. Utilizing vacuum in the correct ways can help with wetting and dispersion When introducing powdered materials into liquids, the goal is always to achieve an air-free dispersion of solids in the…

The Effects of Particle Size on Bulk-Solids Flow Properties

Understanding how particle size affects flow properties helps ensure reliable flow of materials between process steps Many industries utilize dry solid materials and powders (collectively referred to as bulk solids in this article) for producing and manufacturing products. It is…

The Critical Role of Cost Estimation in Successful Project Execution

The ability to forecast costs, align budgets and maintain control throughout the lifecycle of a project can mean the difference between delivering value and facing costly overruns In asset-intensive industries, such as energy, chemicals, power and infrastructure, the balance between…

Taking stock; looking ahead

Year’s end is, of course, the default juncture at which current situations are assessed and forecasts for the future are posited. As this year nears its end, indications are that 2026 will likely be a tough year for much of…

Niobium-based anodes create high-speed lithium ‘highways’

By replacing traditional silicon or graphite anode materials with specially crystallized niobium, manufacturers can overcome some of the safety and power limitations of traditional lithium-ion batteries (LIBs). Echion Technologies Ltd. (Cambridge, U.K.; www.echiontech.com) has developed a proprietary mixed niobium-oxide active…

Method for breakdown and removal of siloxanes from fluids garners patent

Siloxanes — synthetic chains of alternating silicon and oxygen atoms — are widely used in personal care products, soaps, pharmaceutical formulations and other products, but are notoriously difficult to manage in production- and waste-fluid streams. Current approaches, including flaring and…

Measurement and modeling point the way toward optimization of mechanochemical recycling

The widely used plastic polyethylene terephthalate (PET) can be depolymerized by reacting it with sodium hydroxide (NaOH) under strong mechanical impact from metal spheres in a ball mill. This type of mechanochemical route to recycling could alleviate some of the…
