  • Publication number: 20210402346
    Abstract: A radial flow adsorption vessel comprising a cylindrical outer shell having a top end and a bottom end, the top end is enclosed by a vessel head that provides a centrical opening usable as a port to introduce or remove adsorbent particles into or from the vessel; at least one annular adsorption space disposed inside the shell, the at least one annular adsorption space defined by an outer and inner cylindrical porous wall, both co-axially disposed inside the shell; and a loading device for the adsorbent particles positioned above the at least one annular adsorption space at the top end of the vessel, the loading device comprises at least one conical element that extends radially to the outer cylindrical porous wall, the at least one conical element provides a plurality of orifices arranged at least in a region sitting above the at least one annular adsorption space.

  • Patent number: 10994238
    Abstract: The present invention pertains to a radial flow adsorption vessel comprising a cylindrical outer shell and at least one cylindrical porous wall disposed co-axially inside the shell, wherein inside the shell one or more fluid permeable screens are rigidly connected to the at least one cylindrical porous wall, by a multitude of separate standoff elements so that the screen has a cylindrical shape co-axial to the shell, and to an adsorption process using the radial flow adsorption vessel.

  • 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.
