  • Patent number: 9174192
    Abstract: The invention relates to a tube bundle reactor with a flat feed hood. Alternatively, the release hood may also have a flat design. The flat design reduces the heat of reaction which arises in the hood in the case of reaction types which take place not only in the tube bundle (uncatalyzed reactions and reactions with homogeneously distributed catalyst). This greatly suppresses undesired reactions which already take place in the hood owing to accumulated heat, which achieves a higher selectivity in the case of thermally sensitive reactions. In addition, the thermal distribution within the hoods can be controlled precisely. The tube bundle reactor comprises a tube bundle which has a feed end which is connected to a feed hood of the tube bundle reactor, wherein the feed hood is configured in a flat design with a cross-sectional area at the feed end and an internal volume, and the ratio of internal volume to cross-sectional area is less than 0.35 m.

  • Patent number: 7117934
    Abstract: A heat exchange reactor including a housing, a plurality of tubes mounted in the housing and configured to carry a first fluid, and a baffle having a plurality of holes receiving the tubes. The baffle is configured to guide a second fluid provided within the housing to flow in a direction generally perpendicular to the tubes. The reactor includes various configurations for minimizing adverse effects of thermal expansion of the baffle and the tubes. The reactor is configured to minimize mechanical interference between the baffle and the tubes in both an operational state and a non-operational state, for example, by shaping the holes in the baffle to take into account thermal expansion. The reactor also includes a thermal insulator along a length of the tubes at a large temperature gradient zone within the reactor. The reactor further includes a heat transfer fin in contact with only one of the tubes.

  • Patent number: 7036562
    Abstract: A heat exchanger with a core, a support structure and a mount. The core is variable in size and has a lower temperature fluid port and a higher temperature fluid port. The mount is positioned between the core and the support structure, adjacent to the higher temperature fluid port. The mount restrains the core relative to the support structure, such that when the core varies in size it does so either away from or towards the mount. The heat exchanger can also include a deformable connector, including a bellows, a flexible hose and a braided metal hose. The deformable connector is positioned in a manner which allows it and lower temperature fluid port to remain in fluid communication as the core varies in size.

  • Patent number: 7017656
    Abstract: An exemplary heat exchanger includes increased stiffness to prevent buckling of a core. In some examples, an exemplary heat exchanger includes a core and a shaft at least partially positioned therein to increase stiffness of the core and located to limit movement of a heat exchange portion and to receive loads therefrom. In another example, an exemplary heat exchanger includes a core, a duct in fluid communication therewith, a load bearing member positioned adjacent to the core, and a mount which attaches the duct to the member. By connecting the duct to the member, the duct can transfer loads to the load bearing member. This protects the core being damaged by loads applied to the duct. The mount restrains the duct so to transfer loads, from the duct to the load bearing member. Such loads can be from external sources, such as inertia loads and vibration loads.
