High temp. heat exchanger esp. for methane synthesis - has vessel shell and pressure components located in cooler regions

A heat exchanger for two fluids comprises a closed, cylindrical vessel in which tubes for the first fluid pass through the vessel, while the second fluid flows through the spaced around the tubes inside the vessel. All feed and returns pass through the top closure (2) of the vessel. The first fluid tubes lead from the top closure (2) near the outer perimeter down inside the vessel near to the outer wall, turn around in a loop (7,8) and pass back up again into the central region; both ends of the tubes connect to headers (9,9', 10) passing out through the top closure. The outer and inner branches of the looped tubes are separated by an open-bottomed cylindrical shell (3), the top end of which is connected to a concentric second tube (11) around the inner header (10). The second fluid passes through this tube (11) to flow down through the top closure into the vessel. Further concentric tubes (12,12', 13) surround the outer headers (9,9') for the first fluid and also the second tube (11) for the second fluid; these last tubes (12,12', 13) communicate with the annular space outside the open-bottom shell (3) and inside the vessel wall; those concentric tubes (12,12') of this last group which surround the inlet headers for the first fluid constitute the outlet headers for the second fluid. Preferably, the last tube (13) of this last group is equipped with a cooling coil (18).

Der Wärmeübertrager weist ein vertikal angeordnetes Zentralrohr (1) auf, an dem sich in Radial-Axialrichtung bis an ein das Zentralrohr koaxial umgebendes Mantelrohr (30) erstreckende Tragplatten (10) befestigt sind. Die Tragplatten (10) tragen ein Bündel von um das Zentralrohr (1) sich schraubenlinienförmig herumwindenden Wärmeübertragerrohren (16). Im Bereich des oberen und des unteren Endes des Mantelrohres (30) sind Verbindungsöffnungen für ein wärmeabgebendes Medium vorgesehen, das die Wärmeübertragerrohre (16) umströmt. In der Flucht der Tragplatten (10) schließen sich an diese Trennplatten (60) an, die den sich oberhalb der Tragplatten um das Zentralrohr (1) herum erstreckenden Ringraum (54) unterteilen. Hierdurch wird vermieden, daß nach einem Abstellen der Zufuhr des heißen Mediums in den ringsektorförmigen Räumen zwischen den Tragplatten Steig- und Fallströmungen entstehen. The heat exchanger has a vertically arranged central tube (1) on which support plates (10) extending in the radial-axial direction are attached to a jacket tube (30) coaxially surrounding the central tube. The support plates (10) carry a bundle of heat exchanger tubes (16) winding helically around the central tube (1). In the area of the upper and lower end of the jacket tube (30), connection openings are provided for a heat-emitting medium which flows around the heat exchanger tubes (16). In the alignment of the support plates (10), these partition plates (60) are connected, which subdivide the annular space (54) extending above the support plates around the central tube (1). This prevents rising and falling currents from occurring in the annular sector-shaped spaces between the support plates after the supply of the hot medium has been switched off.

System for steam-cracking hydrocarbons and transfer-line exchanger therefor

A system to produce ethylene includes, in one embodiment, separately cracking a heavy hydrocarbon feed and a lighter feed, cooling the latter product in a transfer-line exchanger before admixture with the former product and cooling the mixed product in a transfer-line exchanger. Both exchangers are preferably a novel transfer-line exchanger that has a construction including a vertical tank, with a cylindrical intermediate portion and conical bottom entrance and top exit end portions, tube sheets at the top and bottom ends of the intermediate portion of the tank, vertical tubes extending between the tube sheets and in alignment with openings in the tube sheets. The tubes extend downwardly through the lower tube sheet with their ends at openings in a conical shield that is supported in the entrance conical portion of the tank by the tubes or by the conical entrance portion of the tank. The lower tube sheet has an opening to pass steam into the chamber between that sheet and the shield or steam is introduced into that chamber through the wall of the conical entrance portion of the tank and through the shield. The construction provides egress of steam from this chamber to the entrance end of the tubes below the conical shield for mixture with product to be cooled. When using the novel transfer-line exchanger, the system can provide the cooling of the product from the steam-cracking of the heavier feed without prior admixture with cooled product from the steam-cracking of lighter feed.

Radiation boiler

ABSTRACT OF THE DISCLOSURE An improvement in a radiation boiler for cooling a gas stream con-taining solid and molten particles of the type comprising an inlet for introducing the gas vertically at the top of said radiation boiler, a water bath disposed at the bottom of the radiation boiler for removing the particles after they have been solidified and cooled is disclosed. The improvement resides in the fact that there is disposed between the gas inlet and the water bath, at least two concentrically arranged heat exchange elements, the through passage of the inner heat exchange element being in a fluid flow registry with the feed means. A conical deflector is disposed in registry with the flow of gas passing through annular passage which deflector is disposed at the bottom on the radiation boiler above the water bath, but is at least partially below the lower edge of the vertical wall of the inner heat exchange element. This causes gas which strikes the conical deflector to pass upwardly both in the through passage and in the annular passage between the inner and outer heat exchange elements.
