  • Process for reducing 3,3,3-trifluoropropyne in 2,3,3,3-tetrafluoropropene
    Patent number: 10913697
    Abstract: The invention relates to a process for reducing the concentration of a fluorinated alkyne impurity, such as 3,3,3-trifluoropropyne (TFPY), in 2,3,3,3-tetrafluoropropene (HFO-1234yf) which comprises contacting such a mixture with a caustic material, such as sodium hydroxide (NaOH), under conditions effective to reduce the concentration of the fluorinated alkyne impurity, including in some practices reducing the concentration by at least about 50%.
    Type: Grant
    Filed: November 2, 2017
    Date of Patent: February 9, 2021
    Assignee: Honeywell International Inc.

  • PRESSURE MONITORING SYSTEM
    Publication number: 20080221807
    Abstract: Monitoring pressurized fluid containers through use of a container site subsystem and a system hub. The container site subsystem including sensor(s) to sense a characteristic associated with a pressurized fluid container; and a container site hub to receive, from each sensor, raw data corresponding to the sensed characteristic. The system hub receives the aggregated raw data from the container site hub, and converts the raw data to process values.
