  • Patent number: 12441886
    Abstract: A system for and method of regenerating a siloxane treatment vessel. At least one heat exchanger receives a flow of fluid from the siloxane treatment vessel, and discharges a cooled flow. A knockout tank receives the cooled flow, separates a condensed portion for disposal, and discharges the remainder. A heater raises a temperature of the remainder flow of fluid, and delivers a heated flow to the siloxane treatment vessel.

  • Patent number: 12311314
    Abstract: Systems for and methods of treating a fluid containing siloxanes, silanes and/or other silicon compounds. A hot box is configured to receive an initial flow of the fluid, react the flow with water at a temperature and pressure suitable for hydrolysis to generate a first treated flow, in which at least a portion is hydrolyzed to produce silicon dioxide and methane, and discharge the first treated flow. A solid removal mechanism can be configured to receive the first treated flow, separate at least a portion of the silicon dioxide as solid material, and discharge the remaining components as a second treated flow. Techniques of the present disclosure can lead to very low siloxane levels.

  • Publication number: 20240109053
    Abstract: Disclosed herein are systems and methods for regenerating media in a siloxane removal system. In particular, the present disclosure relates to a method for regenerating an adsorption medium, comprising receiving a source gas stream comprising at least one hydrocarbon and carbon dioxide; separating the source gas stream into a carbon dioxide-rich gas stream, and a substantially carbon dioxide-free gas stream; directing the carbon dioxide-rich gas stream into a regeneration vessel containing an adsorption medium having one or more adsorbed impurities on the adsorption medium; desorbing impurities from the adsorption medium by contacting the adsorption medium with the carbon dioxide-rich gas stream to generate a carbon dioxide-rich gas containing desorbed impurities and a regenerated adsorption medium; and directing the carbon dioxide-rich gas stream containing desorbed impurities out of the regeneration vessel.

  • Patent number: 10843118
    Abstract: A filtration apparatus for filtering a fluid stream includes a vessel housing. At least one cartridge assembly is arranged within the vessel housing. The cartridge assembly includes filtration material arranged between at least one inlet and at least one outlet. The filtration material treats the fluid stream to form a filtered fluid stream. In use, the fluid stream is received a feed port of the vessel housing, flows through the filtration material in the cartridge assembly between the inlet and the outlet, and the filtered fluid stream is discharged from a discharge port of the vessel housing. The filtration apparatus can be used to remove siloxanes from the fluid stream.
