  • Publication number: 20090094894
    Abstract: A process and apparatus for producing a hydrogen-containing gas in a reformer where a furnace, which is independent of the reformer, heats the effluent from a prereformer prior to reacting the prereformer effluent in the reformer. The prereformer effluent may be heated in a heat exchange tube in the furnace where the heat exchange tube is positioned in the furnace to preclude direct radiation from any flames in the furnace thereby preventing local overheating of the heat exchange tube and preventing carbon formation in the heat exchange tube. Fuel and oxidant gas may be introduced into the furnace with significant excess oxidant gas, having a stoichiometric ratio of 1.8 to 2.8 for controlling the temperature of the heat exchange tube.

  • Patent number: 7456374
    Abstract: A heater for fluid flow components. The heater has heat transfer surfaces that engage the component. The transfer surfaces are mounted on jaws that are movable to engage the component. The jaws have massive portions that act as heat reservoirs to maintain a constant temperature in spite of rapid cooling when gas is allowed to expand freely from the component. The jaws are heated by electrical resistive heating elements that are sealingly mounted within the massive portions. The sealing engagement allows the heater to be used in hazardous environments.

  • Patent number: 7201018
    Abstract: The invention relates to a process and apparatus for delivering an ultra high purity fluid comprising at least one component to a point of use at a required pressure without mechanical pumping. In one embodiment, a high purity feed comprising at least one component in gaseous or liquid form is charged into a vessel and at least partially converted to a solid phase source. As the feed is converted to a solid phase source, additional feed may be added until the vessel is at least substantially filled with a solid phase source or slush. Once filled, the solid phase source or slush may be isochorically heated whereby the solid phase source is converted to a product at an elevated pressure.

  • Patent number: 7069742
    Abstract: This invention relates to an improvement in a process and apparatus for delivering ultra high purity liquid carbon dioxide to a point of use at pressures above ambient without pumping. In the process a high purity carbon dioxide feed is charged to a vessel and at least partially solidified. Once filled, the slush or solid is isochorically heated, i.e., heated at constant vessel volume whereby the solid phase carbon dioxide is converted to a liquid. Liquid, then, is withdrawn from the vessel at a desired pressure at a rate at which the solid phase carbon dioxide is converted to a liquid. The improvement resides in effecting partial solidification and recycle of carbon dioxide.

  • Patent number: 6901941
    Abstract: A vessel for the storage and transportation of bulk volumes of a fluid is described herein and a method for using same. The vessel contains a plurality of dividers that apportion the internal volume into a number of sections. The dividers within the vessel aid in minimizing sloshing of the fluid contained therein during transport. In addition, the dividers optimize the fluid flow pattern thereby allowing for the continuous purge of the vessel without the need for the application of a partial or full vacuum.

  • Patent number: 6814092
    Abstract: A process and system for conditioning a bulk container for ultra-high purity liquefied gas. Vapor is generated in the container from a conditioning quantity of the ultra-high purity liquefied gas by imposing a temperature difference on the container so that the vapor condenses when a temperature difference is achieved. The resulting liquid reflux, e.g., the condensed liquid drips or flows back to the conditioning quantity of the liquified gas, washes or removes contaminants, e.g., particles, metal and moisture, from the interior surface of the container. A portion of the vapor is vented from the container for reclamation. The used conditioning liquid may also be reclaimed.
