摘要： Hydrogen purification devices and their components are disclosed. In some embodiments, the devices may include at least one foil-microscreen assembly disposed between and secured to first and second end frames. The at least one foil-microscreen assembly may include at least one hydrogen-selective membrane and at least one microscreen structure including a non-porous planar sheet having a plurality of apertures forming a plurality of fluid passages. The planar sheet may include generally opposed planar surfaces configured to provide support to the permeate side. The plurality of fluid passages may extend between the opposed surfaces. The at least one hydrogen-selective membrane may be metallurgically bonded to the at least one microscreen structure.

摘要： Hydrogen generation assemblies, hydrogen purification devices, and their components are disclosed. In some embodiments, the devices may include a permeate frame with a membrane support structure having first and second membrane support plates that are free from perforations and that include a plurality of microgrooves configured to provide flow channels for at least part of the permeate stream. In some embodiments, the assemblies may include a return conduit fluidly connecting a buffer tank and a reformate conduit, a return valve assembly configured to manage flow in the return conduit, and a control assembly configured to operate a fuel processing assembly between run and standby modes based, at least in part, on detected pressure in the buffer tank and configured to direct the return valve assembly to allow product hydrogen stream to flow from the buffer tank to the reformate conduit when the fuel processing assembly is in the standby mode.

摘要： Hydrogen generation assemblies and methods of generating hydrogen are disclosed. In some embodiments, the method may include receiving a feed stream in a fuel processing assembly of the hydrogen generation assembly; and generating a product hydrogen stream in the fuel processing assembly from the received feed stream. Generating a product hydrogen stream may, in some embodiments, include generating an output stream in a hydrogen generating region from the received feed stream, and generating the product hydrogen stream in a purification region from the output stream. The method may additionally include receiving the generated product hydrogen stream in a buffer tank of the hydrogen generation assembly; and detecting pressure in the buffer tank via a tank sensor assembly. The method may further include stopping generation of the product hydrogen stream in the fuel processing assembly when the detected pressure in the buffer tank is above a predetermined maximum pressure.

摘要： Refining assemblies and methods for refining rich natural gas containing a first methane gas and other hydrocarbons that are heavier than methane gas are disclosed. In some embodiments, the assemblies may include a methane-producing assembly configured to receive at least one liquid-containing feed stream that includes water and rich natural gas and to produce an output stream therefrom by (a) converting at least a substantial portion of the other hydrocarbons of the rich natural gas with the water to a second methane gas, a lesser portion of the water, and other gases, and (b) allowing at least a substantial portion of the first methane gas from the rich natural gas to pass through the methane-producing assembly unconverted. The assemblies may additionally include a purification assembly configured to receive the output stream and to produce a methane-rich stream therefrom having a greater methane concentration than the output stream.
