Calcium-sulfonate complex greases are widely used in applications in the pulp-and-paper, marine and steel-manufacturing sectors. Within an ever-volatile lithium market, calcium-sulfonate greases are increasingly seen as a reliable alternative to lithium-based greases. However, typical methods for preparing high-performance calcium-sulfonate grease…
A research team led by Kenneth C. Neyerlin at the National Renewable Energy Laboratory (NREL; Golden, Colo.; www.nrel.gov), with members from Argonne National Laboratory (Lemont, Ill; www.anl.gov) and Oak Ridge National Laboratory (Tenn.; www.ornl.gov) has developed a membrane electrode assembly…
The V-Cone Blenders utilize diffusion as the main mechanism for mixing. As the V-shaped vessel rotates on its horizontal axis, batch materials cascade down, distributing particles over a freshly exposed surface. With operating speeds of 5 to 25 rpm, this…

The recycling plant…
An Oak Ridge National Laboratory (ORNL) team created and tested two different formulations for stationary batteries that could utilize CO2 from industrial sources while storing energy from wind turbines and solar panels. Consisting of two electrodes in a saltwater solution,…
Current hydrogen demand is dominated by petroleum refining and fertilizer production, and is supplied largely by fossil-fuel-based steam-methane reforming (SMR). Increasingly, however, demand for hydrogen will come from the energy transition, and will be supplied by a more diverse range…
This company has introduced new 6- and 8-in. valve sizes for its Model CV valve product line (photo). The new valves are available in actuated and manual versions with both featuring a Class 150 pressure rating. Additionally, the company is…
Traditionally, many polymerization reactions are carried out batchwise in reactor vessels, with the reaction taking place in solution, emulsion or in a melt. This procedure reaches its limits if, for example, the reaction is very exothermic or the viscosity increases…
The FIT in-plant and Foresight overland conveyors reliably transport material in the mining industry. The standardized conveyor modules and premium components offer high capacity and layout flexibility, as well as substantial savings in time and resources. The high-capacity Foresight overland…
A new 1-ft 3 (28-L) capacity Vee Cone Blender model VB-1-SSIS (photo) is suitable for laboratory and pilot applications. Constructed and finished to sanitary standards, it is equipped with an internal spray line with intensifier bar for rapid dispersion of…
