    摘要: With a method for operating a tube bundle reactor for exothermic gas phase reactions having a tube bundle with catalyst-filled reaction tubes (2), wherein the one ends of the reaction tubes are spanned by a gas inlet hood and the other ends are spanned by a gas outlet hood and wherein around the outside of the reaction tubes a heat transfer medium flows to carry off reaction heat. An explosive gas mixture (G) is introduced into the reaction tubes (2) via the gas inlet hood and after reaction the gas mixture (G), that may still be explosive, it is led off from the reaction tubes via the gas outlet hood. A limit temperature in the reaction tubes (2) is specified that lies above the normal operating temperatures in the reaction tubes (2) but at most equals the ignition temperature of the explosive gas mixture (G) Each non-operating high temperature region (7) forming in the reaction tubes (2) whose temperature is at least equal to the limit temperature and which migrates in the respective reaction tube (2) in the longitudinal direction thereof is stopped while still in the reaction tube (2) so that the high temperature region (7) is prevented from advancing into the gas inlet hood or the gas outlet hood.

    摘要: A tube bundle reactor for carrying out catalytic gas phase reactions, particularly methanation reactions, has a bundle of catalyst-filled reaction tubes through which reaction gas flows and around which heat carrier flows during operation. In the region of the catalyst filling, the reaction tubes run through at least two heat carrier zones which are separated from one another, the first of which heat carrier zones extends over the starting region of the catalyst filling. The reaction tubes each have a first reaction tube portion with a first hydraulic diameter of the catalyst filling and, downstream thereof in flow direction of the reaction gas, at least a second reaction tube portion with a second hydraulic diameter of the catalyst filling that is greater than the first hydraulic diameter of the catalyst filling.

    摘要: A cooling system for use in a shell-type reactor includes vertically extending double tubes with an inner tube and an outer tube closed at its lower end. The system also includes a distributor for supplying a fluid cooling medium into the upper end of the inner tubes and a horizontally extending plate, which on its upper surface includes at least two upwardly open, parallel grooves. Two adjacent grooves are separated by a common inner wall. At least one outer tube, having an upper end, is disposed in each groove, through the plate. Each outer tube is tightly welded to the plate on the groove base. The upper, open side of each groove is closed with a lid, so that each groove forms a collector for discharging the cooling medium from the outer tubes. Each inner tube opens through the lid into a distributor and is tightly attached to the lid.

    摘要: A set of prefabricated tube bundle reactor subassemblies is proposed which are adapted to be assembled at a construction site to provide a tube bundle reactor for carrying out catalytic gas and/or liquid phase reactions. In accordance with the invention, the reactor shell and the reactor heads, on the one hand, and the tube bundle and the tube sheets, on the other hand, form separate subassemblies, more specifically at least one shell/head subassembly, at least one head subassembly, and at least one tube bundle subassembly. The subassemblies comprise means for vertically supporting the tube bundle subassembly and for pressure tightly connecting the shell/head subassembly to the tube sheets without requiring heat treatment during assembly of the subassemblies. Likewise proposed are a tube bundle reactor for carrying out catalytic gas and/or liquid phase reactions and an arrangement of the kind of tube bundle reactors mentioned.
