Facts At Your Fingertips: Predictive Maintenance Methods

Predictive maintenance (PdM) programs can provide advanced warning of equipment problems and potential failures. This one-page reference provides brief descriptions of six common predictive maintenance methods. Infrared thermography Continuous monitoring of equipment temperature over time has the potential to identify…

Selective separation of individual rare-earth elements using DGA-based ligands

Utilizing rare-earth elements (REEs), such as for permanent magnets in renewable energy applications, requires costly chemical separations that generate large volumes of waste. A process featuring new diglycolamide (DGA)-based ligands and liquid-liquid extraction exhibits more effective separation of individual REEs,…

An efficient cleaning system for mixers

Automatic WIP-Systems (photo) provide a reliable and repeatable process for cleaning mixing systems — such as the Ploughshare Mixers — an important task especially in life-science applications. A smart arrangement of rotating cleaning nozzles inside the mixing drum ensures a…

Recycling polyesters, polycarbonates and more — at room temperature

A new catalytic recycling method that avoids harsh processing conditions could widely expand the recyclability of a broad range of plastics, including polycarbonates, polyesters and mixed-waste feeds. Researchers from the Center for Sustainable and Circular Technologies (CSCT; www.ccst.ac.uk) at the…

A polymer pelletizer for when capacities are high

The Pearlo 350 EAC underwater pelletizing system (photo) has a liquid-heated die plate for high capacities, delivering throughputs of 18,000 kg/h of virgin polymer. The unique cutting-blade design and optimum water- and material-flow conditions within the cutting chamber provide not…

Multi-diaphragm dosing pump is virtually maintenance-free

The Chem-Feed CD1 (photo) is engineered to ensure almost no maintenance requirement for the life of the pump. CD1 is suitable for dosing with gas-forming chemicals, such as peracetic acid or sodium hypochlorite. The CD1 Dual Diaphragm Hyperlink Drive Technology…
