  • Patent number: 9255646
    Abstract: Excess flow shutoff valve comprising a valve body, a valve plug, a partition, and an activation component where the valve plug, the partition, and activation component are disposed within the valve body. A suitable flow restriction is provided to create a pressure difference between the upstream end of the valve plug and the downstream end of the valve plug when fluid flows through the valve body. The pressure difference exceeds a target pressure difference needed to activate the activation component when fluid flow through the valve body is higher than a desired rate, and thereby closes the valve.

  • Patent number: 8178075
    Abstract: A tubular reactor and method for producing a product mixture in a tubular reactor where the tubular reactor comprises an internal catalytic insert having orifices for forming fluid jets for impinging the fluid on the tube wall. Jet impingement is used to improve heat transfer between the fluid in the tube and the tube wall in a non-adiabatic reactor. The tubular reactor and method may be used for endothermic reactions such as steam methane reforming and for exothermic reactions such as methanation.

  • Patent number: 7871579
    Abstract: A tubular reactor having an insert for improving heat transfer characteristics of the tubular reactor. The insert comprises a catalyst and metal structures consecutively arranged in a lengthwise direction of the tube. The metal structures have radially expandable side walls and orifices for squeezing fluid between the metal structures and the tube wall. The radially expandable side walls form hollows between the radially expandable side walls and the tube wall of the tubular reactor. The radially expandable side walls deform responsive to the fluid pressure difference between the inside of the metal structure and the outer space between the metal structure and the tube wall thereby maintaining the gap between the orifice opening and the tube wall to adjust for tube creep.

  • Patent number: 5814129
    Abstract: Apparatus and method to improve flow of fluid through an annular bed in a radial flow treatment vessel. An elongated annular baffle is disposed in the reactor adjacent the bed to impart generally U-shaped flow to the fluid either prior to entering or after it exits the bed thus achieving an overall serpentine or reverse U-shaped flow pattern as the fluid proceeds from an entry port to an exit port in the reactor. Means are provided in the baffle to permit minor amounts of fluid to bypass the generally U-shaped flow path in order to correct fluid flow maldistribution through the bed that is attributed to frictional pressure drop in the flow channels adjacent to the bed. A vessel according to the invention can be operated with fluid flow through the vessel in either direction.
