  • Alkylene oxide purification processes and systems
    Patent number: 8845863
    Abstract: Processes and systems for purifying ethylene oxide, including introducing a feed stream including ethylene oxide to a heat exchanger to heat the feed stream, feeding the heated feed stream to a distillation apparatus base below a first stage, removing from the distillation apparatus an impurity fraction as a top exit stream from the distillation apparatus located at a top take-off on the distillation apparatus, removing from the distillation apparatus an ethylene oxide stream of 99.7 weight percent purity, based on the total weight of the ethylene oxide stream, from the distillation apparatus, and removing from the distillation apparatus an aldehyde enriched fraction as a bottom stream from the distillation apparatus, where the aldehyde enriched fraction is fed directly to a glycol reactor.
    Type: Grant

    Date of Patent: September 30, 2014
    Assignee: Dow Technology Investments LLC
    Inventors: Clarence P. Stadlwieser, Bernie B. Osborne, John P. Dever, Harvey E. Andresen, Michael L. Hutchison, Steven R. Osborne, Liping L. Zhang, Michael Habenschuss, Andrew Addie, Donald R. Culp
  • THERMAL ENERGY STORAGE APPARATUS
    Publication number: 20100287933
    Abstract: A thermal energy storage apparatus capable of storing large quantities of heat uses a plurality of energy storage zones having essentially the same thermal energy storage capacity per zone. The flow of a fluid into each zone is separately and independently controlled thereby creating a modular system that is capable of responding to rapid changes in the supply of and/or demand for thermal energy.
