Facts At Your Fingertips: Flexible Intermediate Bulk Containers
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…
Modular, low-cost ammonia-production system is designed for intermittent energy
Ammonia is a critical input for agricultural fertilizers, but NH3 production is plagued by volatile prices, difficult global logistics and high CO2 emissions. A new NH3-production system from the startup TalusAg (Austin, Texas; www.talusag.com) addresses these challenges with a modular…
Waterless technology uses supercritical CO2 to recycle textile waste
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…
Refiners Pursue Flexibility Amid Economic Headwinds
Petroleum refiners are taking steps to support and increase operational flexibility and business agility as logistical challenges and economic headwinds build, and policy certainty is difficult to find Amid the current economic climate, business agility and operational flexibility have emerged…
Rotating bioreactor scheme accelerates production of high-value products
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…
PVC polymer chlorination with LEDs enhances resin stability
Lubrizol (Cleveland, Ohio; www.lubrizol.com) recently began producing chlorinated polyvinyl chloride (CPVC) resin in commercial reactors equipped with light-emitting diodes (LEDs) as the light source, instead of the conventional mercury lamps. The company’s LED reactor technology enhances the thermal stability of…

Recent Updates to Non-Metallic Piping Standards
As applications, risks and materials continue to evolve, it is vital that engineers stay abreast of revisions to the standards that govern non-metallic piping systems Recent advancements in standards developed by the American Society of Mechanical Engineers (ASME; New York,…
Focus On: Pressure Measurement
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…
Molten-salt nuclear reactors take the next step toward industrial deployment
Over decades of experimentation, molten-salt nuclear reactors have been shown to deliver high-temperature heat and extremely efficient electricity at reduced pressures. However, these reactors have yet to make the leap into widespread industrial adoption. Terrestrial Energy Inc. (Charlotte, N.C.; www.terrestrialenergy.com)…
