  • Patent number: 10465565
    Abstract: A CO2 energy storage system includes a storage tank that stores a CO2 slurry, including dry ice and liquid CO2, at CO2 triple point temperature and pressure conditions. The storage system also includes a first pump coupled in flow communication with the storage tank. The first pump is configured to receive the CO2 slurry from the storage tank and to increase a pressure of the CO2 slurry to a pressure above the CO2 triple point pressure. The energy storage system further includes a contactor coupled in flow communication with the first pump. The contactor is configured to receive the high pressure CO2 slurry from the pump and to receive a first flow of gaseous CO2 at a pressure above the CO2 triple point pressure. The gaseous CO2 is contacted and then condensed by the melting dry ice in the slurry to generate liquid CO2.

  • Publication number: 20110021824
    Abstract: This invention relates generally to non-ionic X-ray contrast agents. It further relates to a method of using solid adsorbents to reduce backpeaks content in the purification of iodixanol. In particular, it relates to the use of non-polar organic adsorbents with the average pore diameter smaller than about 30 nm. Specific examples of adsorbents of the instant invention include non-polar acrylic ester, di-vinyl benzene resins, poly-styrene di-vinyl benzene resins, and carbon adsorbents. In certain embodiments, upwards of 30% of the backpeak levels and 60% N-acetyl cyclic iodixanol levels are reduced for a 5% loss of iodixanol.

  • Patent number: 7863463
    Abstract: Disclosed herein is a method for purification of dianhydrides comprising a substantial amount (10000 ppm or more) of at least one metal salt. In one aspect the method is useful for the purification of dianhydrides prepared by the reaction of a halophthalic anhydride with a metal carbonate and may be optionally catalyzed by a phase transfer catalyst. The purification of the dianhydrides may be accomplished by hydrolyzing the dianhydride metal salt mixture directly to a tetraacid with an inorganic acid, followed by separating the impurities from an aqueous phase, and subsequently heating the tetraacid to effect ring closure to form a purified dianhydride having less than 50 parts per million metal halide and lower levels of other residual impurities. In one aspect the method is highly effective in removing phase transfer catalyst impurities such as hexalkylguanidinium halides initially present in the dianhydride undergoing purification.
