Centrifugation is the method of choice in the chemical process industries (CPI) for separating solids from liquids. It relies on the G-forces generated by high-speed rotation to recover solids or liquids from slurries, as well as clarify liquids or classify solids. Centrifuges can be categorized as either sedimentation or filtration units. Sedimentation centrifugation relies on a difference in density...

  A high-shear reactor that is said to accelerate chemical reaction rates by up to three orders of magnitude will get its first commercial tryout in the production of biodiesel fuel. Kreido Biofuels, Inc. (Camarillo, Calif.;, the reactor's developer, will shortly start up a unit for Foothills Bio-Energies (Lenoir, N.C.;, where it will add 1 million gal/yr to the...

Winemaking still involves traditional batchwise processing steps, such as batch fining with bentonite clay to prevent heat instability in protein haze formation. This is typically done by adding “rule-of-thumb” amounts of clay, allowing it to settle and decanting the wine. Now, researchers from the Deparment of Chemical Engineering, Adelaide...

A process that can enrich highly contaminated natural gas has been developed at Eindhoven University of Technology (Netherlands;, with support from the Royal Shell/Dutch Group. The device shows promise as a way to utilize the large quantities of natural gas that is currently unusable because of high concentrations of carbon dioxide and hydrogen sulfide. Existing technology, such...
