  • Exchanger-reactor with bayonet tubes and chimneys suspended from the upper dome of the reactor
    Patent number: 8673231
    Abstract: The present invention describes a vertical cylindrical exchanger-reactor for carrying out endothermic reactions, comprising a shell enclosing a plurality of tubes inside which the reactive fluid moves, said tubes being of the bayonet type, and the heat transfer fluid, in this case hot gases, being channeled inside chimneys surrounding said bayonet tubes. The bayonet tubes and the chimneys are suspended from the upper dome of the reactor. This reactor may operate with a pressure difference between the tube side and the shell of up to 100 bars. The hot gases are admitted into the reactor at temperatures of up to 1300° C.

  • EXCHANGER-REACTOR WITH BAYONET TUBES AND CHIMNEYS SUSPENDED FROM THE UPPER DOME OF THE REACTOR
    Publication number: 20120006516
    Abstract: The present invention describes a vertical cylindrical exchanger-reactor for carrying out endothermic reactions, comprising a shell enclosing a plurality of tubes inside which the reactive fluid moves, said tubes being of the bayonet type, and the heat transfer fluid, in this case hot gases, being channelled inside chimneys surrounding said bayonet tubes. The bayonet tubes and the chimneys are suspended from the upper dome of the reactor. This reactor may operate with a pressure difference between the tube side and the shell of up to 100 bars. The hot gases are admitted into the reactor at temperatures of up to 1300° C.
