  • Process and Apparatus for Improved Recovery of Argon
    Publication number: 20240125550
    Abstract: A process and apparatus for recovering at least argon from a feed gas that can provide an improved recovery of argon as well as an improvement in operational efficiency. Some embodiments can be adapted so that the improved argon recovery can also be obtained with improved condenser operation for an argon column without requiring an increase in power for the recovery of the argon. Some embodiments can utilize a reboiler positioned near or at the bottom of argon recovery column to increase boil-up therein and/or provide added heat duty to drive a condenser of the argon recovery column to provide improved argon recovery.

  • Cinnamic acid-based oligomers and uses thereof
    Patent number: 8993620
    Abstract: Cinnamic acid-based oligomers and therapeutic uses thereof are provided. The oligomers are used as anti-inflammation agents, inhibitors of elastase and anti-oxidants, and in some cases (e.g. the treatment of lung disorders such as lung cancer) all three activities are simultaneously beneficial. Subsets of the oligomers (e.g. ?-O4 and ?-5 trimers and tetramers) are used as anticoagulants.
