PROBLEM TO BE SOLVED: To optimize inspection and maintenance stages while simplifying handling operation. SOLUTION: A pipe group of a heat exchanger contained in a three-phase fluidized bed reactor comprising a jacket, which has an introduction means of reaction fluid, an introduction means of cooling fluid, and a discharge means of the partially evaporated cooling fluid includes at least two stages of the same modules, each module including a group of the same pins distributed around a central pipe common to a considered module and a module group disposed vertically to the module in the pipe group of each stage. The central pipe supplies the cooling fluid to the pins of the modules and also plays the role of recovering the partially evaporated cooling fluid leaving the pins. COPYRIGHT: (C)2008,JPO&INPIT |
