The presence of per- and polyfluoroalkyl substances (PFAS) in wastewater and groundwater has garnered increased attention as a health and environmental issue because of their recalcitrance and bioaccumulation. To complement existing PFAS separation technologies, the Battelle Memorial Institute (Columbus, Ohio;…
This company has introduced a range of ultra-low profile bolt-load washers that is ideal for bolt-load and tensioner tool calibration. Called TensionDisc (photo), the washers are specially designed load sensors that monitor bolt loads in bolted joint assemblies. A simple…
When a pump operates inefficiently, or fails all together, the challenge is to make the most economical decision on how to remedy the situation. Some guidance is provided here Centrifugal pumps are widely used throughout the chemical process industries (CPI).…
Converting propane to propylene by oxidative dehydrogenation with CO2 is an alternative route to conventional propane dehydrogenation, but existing catalysts for this conversion are not very efficient. Now, in a study described in a recent issue of Nature Catalysis, researchers…
Evaporation and crystallization technologies have the ability to create advantages for pulping facilities by improving operational efficiency and reducing waste, while simultaneously producing high-value product streams The emergence of new products and markets is driving a global renaissance of the…
Condition monitoring for predictive maintenance (photo) is a drive solution that focuses on status-oriented maintenance rather than traditional time-based maintenance. Status and drive data are recorded periodically or continuously via the programmable logic controller (PLC) output parameters and can be…
A new class of electrolyte aims to bridge the performance gaps between the electrolytes used in conventional lithium-ion batteries and solid-state batteries. The new rubber electrolytes, developed by a team of researchers from Georgia Institute of Technology (Georgia Tech; Atlanta;…
The custom designed three-stage heat exchanger (photo) will be used to increase temperature of a 25,000 std. ft3/min airflow from 50°F to 330°F using 145 psig steam. Each stage is nearly 7 ft tall and 8 ft wide. Heated air…
Many factors impact the performance of synthetic filtration media, from thread and weave styles to drainage and coverage considerations Under the broad umbrella of filter media, there are many synthetic media materials, including woven filter cloths, woven and non-woven fabric…
The Fisher WhisperTube Modal Attenuator (photo) was introduced recently for noisy gas or vapor applications. The modal attenuator is a full-bore device offering 15-dB sound suppression to reduce noise inside pipes produced by sources upstream, such as control valves, pressure-relief…
