Researchers at the Dept. of Chemical Engineering, University of Texas at Austin (edlinks.chemengonline.com/5827-547) have developed a rubbery membrane that can be used purify hydrogen. The membrane, based on ethylene oxide polymers, is 40 times more permeable to CO2 than H2,…
A gas-liquid nozzle that reduces the size of the gas bubbles blown into a liquid — thus increasing the rate at which the gas is absorbed into the liquid — has been developed by a research team led by Jie…
Cyclones are among the simplest and most easily fabricated pieces of processing equipment. They are used extensively in the chemical process industries (CPI) for gas-solids separation. In petroleum refineries, for example, cyclones are used in the reactors and regenerators of…
