  • ABSORPTION MEDIUM AND METHOD FOR ABSORPTION OF AN ACID GAS FROM A GAS MIXTURE
    Publication number: 20140090558
    Abstract: An absorption medium which comprises water, an amine (A) of formula (I) in which R is an n-alkyl radical having 1 to 4 carbon atoms, and an alkanolamine (B) which is a tertiary amine or a sterically hindered primary or secondary amine has a high absorption capacity for CO2 with a high absorption rate. In the absorption of acid gases from a gas mixture a separation of the absorption medium into two liquid phases or the precipitation of a solid upon absorption of CO2 and regeneration of the absorption medium can be avoided with the absorption medium, even without addition of a solvent.

  • Rotary atomizer for particulate paints
    Patent number: 8590813
    Abstract: A rotary atomizer applies particulate paints with good color matching by reducing paint droplet size deviation and then optimizing the other paint spraying parameters. Paint droplet size parameters are reduced by using a bell cup having reduced flow deviations, including an overflow surface having a generally constant angle between a deflector and an atomizing edge.
