  • Splash guard for vented containers
    Patent number: 12060205
    Abstract: The present disclosure provides a splash guard to minimize potential contact between the chemical product and a vent membrane during transport and/or transfer of containers, thereby resulting in preservation of the integrity of a vent membrane during transport and/or transfer of a chemical product. The splash guard is affixed to the fitment and so can be removed from the interior of the container prior to transfer of the chemical product out of the container. The splash guard may be used with fitments of varied shapes, sizes and/or structures, and with containers of varied shapes, sizes and/or structures. The splash guard is easy and inexpensive to manufacture and easy to install, e.g., by snapping onto a ring (lower perimeter) of a fitment. For example, the splash guard covers the entire circumference of the neck of a container, and is formed of a moldable material that provides rigidity.

  • Combined cycle power plant utilizing organic water additives
    Patent number: 12049419
    Abstract: Organic water conditioning agents may be added to an aqueous stream that is supplied to a steam generator, such as a heat recovery steam generator within a combined cycle power plant. These organic water conditioning agents may degrade to electrically-charged decomposition products that can interfere with cation conductivity measurements made on the aqueous stream. To allow deployment of the organic water conditioning agents, a sampling device can process aqueous samples to destroy interfering organic molecules, such as through heat or irradiation. Cation conductivity measurements can then be made on the aqueous sample after destroying and removing interfering organic species from the sample stream.
