Abstract:
1. Heat exchange bundle contained in the inside of a reactor for Fischer-Tropsch synthesis comprising a casing and fitted with means of introducing reaction fluids, means of introducing a coolant and means of evacuating said partially vaporized coolant, said bundle comprising at least two stages of identical modules, each module comprising sets of identical hairpins configured as pipes arranged in series and connected to one another by U-bends, the hairpins being distributed around the central tube common to the module in question and the modules being vertically aligned with the module in question at the different stages of the bundle, in which said central tube has separations permitting at the same time supply of coolant to the hairpins of the module and the recovery of the coolant from the hairpins when the coolant is partially vaporized from the same hairpins due to heat from reaction of the reagents.
