  • Publication number: 20120130026
    Abstract: Method of reducing fouling in an elastomer polymerization process that includes providing a reactor capable of housing an industrial-scale elastomer polymerization reaction, and applying a mechanical force to the reactor so as to create a vibration in at least one wall of the reactor, in which fouling is reduced in the reactor. In one embodiment the reaction is an industrial scale butyl polymerization reaction and the reactor is a butyl polymerization reactor.

  • Patent number: 7721605
    Abstract: The present invention is a mechanical oscillator for detection and measurement of corrosive foreign materials. The elements include a mechanical oscillator that is mechanically excited, wherein the mechanical oscillator has a resonant frequency, f, and a quality factor, Q. A fuse fixed to the oscillator to change oscillator amplitude to and from essentially zero to resonance amplitude. In a preferred embodiment, the mechanical oscillator has the shape of a tuning fork where one region is compatible with the service fluid and the other region is incompatible with the service fluid or other contaminant. The sensor alarms when a measured amount of the incompatible material has been removed or the physical strength of the material has been compromised.
