This article made available to you by: This article provides an overview of the engineering, design and operational considerations associated with reactors and vessels, bridging the gap between theoretical design codes and applied process engineering Pressure vessels and reactors are…
This pressure transmitter works without a PLC The 4051S pressure transmitter (photo) provides local real-time control, eliminating the need for a separate device, such as a programmable logic controller. This functionality is provided by two relay switches, each of which…
A team of researchers at Iowa State University (ISU; Ames; www.iastate.edu) have developed a new bioreactor concept that streamlines production of value-added bioproducts at smaller scales by integrating three process steps (fermentation, product extraction and separation) into a single, compact…
Direct battery-recycling methods, such as re-lithiation — where depleted lithium is replenished directly onto cathodes via a solid-state reaction — hold many benefits over indirect methods, such as those relying on hydrometallurgy or pyrometallurgy, where cathodic structures are destroyed in…
Textile waste is one of the fastest-growing waste streams globally, and there are limited options available to efficiently recycle end-of-life textiles into useful materials. A new recycling approach developed by Renasens (Stockholm, Sweden; www.renasens.com) utilizes supercritical CO2 to recover intact…
A process for making pigments from cellulose for use in cosmetics, food and coatings applications has scaled up from a 1-ton/yr pilot unit to a process capable of generating multiple-hundreds of tons per year in a toll-manufacturing setting. The cellulose-derived…
The continued and expanding use of digitalization technologies in the process industries have pushed facility operations from “automated” — featuring distributed control systems, programmable logic controllers, safety instrumented systems and others — toward “autonomous” operations, where technologies like machine-learning, open-software-defined…
By applying concentrated mechanical force, high-impact tank-cleaning systems can overcome the limitations of traditional cleaning methods in certain applications Tank cleaning in specialty chemical manufacturing isn’t just routine maintenance. It directly affects product quality, production schedules, worker safety and the…
Flexible intermediate bulk containers (fIBCs) are large, collapsible woven containers designed for transporting and storing of dry, flowable materials, such as powders, grains and granules, in industrial settings. This one-page reference summarizes the available options for flexible IBCs. Normally made…
Synthesis of methanol from carbon dioxide is among the key goals for net-zero-CO2 production of chemicals and fuels. Previous investigation has suggested that indium oxide could serve as an effective catalyst for this reaction, but the structural details of the…
