Definitions

  • the invention relates to a device for carrying out chemical reactions, in particular for carrying out exothermic and highly exothermic reactions in which a gas phase is passed over a Festgut thoroughlyung and reacted.
  • tube bundle reactors Strong exothermic reactions are usually carried out in tube bundle reactors by means of a heterogeneous catalyst.
  • Numerous examples are available in the literature: According to EP 0 188 532 (Nippon Kayaku) or JP 11080052 (Toa Gosei Chemical Industry Co.), tube bundle reactors are used to convert propene to acrolein and acrylic acid. According to DE 102 60 094 (BASF AG), tube bundle reactors are likewise used for the preparation of cyclic diisocyanates.
  • Reactors of this type are not very flexible use. So u.a. with the number of tubes of the reactor, the nominal capacity of the reactor. By suitable closing of individual tubes, this can indeed be reduced, but an increase in the nominal capacity is not possible without much effort.
  • the objects of the invention is to provide a flexible reactor. This is to be understood that z. B. a changing reaction performance over the life of the catalyst may require an adjustment of the reaction area. It could also be expedient, for example, to exchange tubes for one or more hordes or plates. Even a cleaning, repairs or catalyst change force in a conventional
  • the invention relates to a device serving as a reactor for carrying out exothermic chemical reactions, which consists of a housing and a reaction-carrying unit, with detailed technical solutions by the entire reactor meets the requirements of functionality, pressure and temperature.
  • the passages of the lines leading in or out of the reaction-leading unit are supplemented by the housing wall by force-absorbing units.
  • the reaction unit is interchangeably installed by the arrangement of a main flange connection in the upper third of the housing (reactor hood), with which it can be separated from the rest of the housing.
  • reaction-carrying unit for example in the form of an array of tubes, plates or one or more hordes (bundled tubes or plates) can be used interchangeably.
  • This unit is preferably introduced suspended or standing in the reactor jacket.
  • the reaction-filling unit filling the housing may consist of a plurality of modules arranged side by side and / or one another be attached to each other. The number n of these modules can be up to 10.
  • the reactor on which the invention is based is particularly suitable for carrying out exothermic and strongly exothermic reactions in which the educt gas is reacted by means of a heterogeneous catalyst.
  • the apparatus is suitable for the exothermic conversion of methanol with H2S to methylmercaptan.
  • the apparatus also for the implementation z. B. a C3 component at a higher temperature over a heterogeneous mixed oxide catalyst with oxygen, water vapor and / or an inert gas or preferably an exhaust gas from the reaction, from which the condensable components are separated.
  • the construction of the reactor housing is characterized in that, in contrast to conventional tube bundle reactors, the reaction space, designed as a pressure chamber, encloses the cooling space.
  • the reaction space designed as a pressure chamber
  • Part of the inventive concept is the rapid interchangeability of the reaction-bearing unit.
  • an embodiment of the invention consists of a reactor housing which is connected via a force-absorbing unit to the reaction-carrying unit.
  • the reaction-carrying units can be suspended or anchored to the reactor housing, so that, depending on the arrangement, the upper or the lower side of the reaction-carrying unit can expand or contract with thermal stresses.
  • the reactor shell is equipped with a force - absorbing unit in such a way that these are responsible for the passage of the incoming or outgoing Lines located on the inside of the reactor shell or on the outside of the reactor shell.
  • the force-absorbing unit is able to absorb the elongation or shortening of the reaction-bearing unit and thereby compensate for the stresses on the passages of the reactor shell.
  • EP 0895806 and EP 1048343 A2 describe the compensation of the stresses by the principle of convolution.
  • Another embodiment is that the incoming or outgoing lines are guided in a bent and thus in a sufficiently elastic form (see Figure 2).
  • Another object of the invention is an arrangement of the reaction-carrying unit, which is advantageously attached in a hanging position on the reactor hood. For example, by arranging a main flange connection in the upper region of the housing (reactor hood), preferably in the upper third, a rapid change of the reaction-carrying units, in whole or in part, can be carried out.
  • the device on which the invention is based is particularly suitable for carrying out exothermic and strongly exothermic reactions, in which a gas phase is passed over a solids bed and reacted.
  • This reaction can be, for example, the conversion of methanol with H 2 S to methyl mercaptan, which proceeds heterogeneously catalyzed at elevated pressure and temperature with exothermic heat generation.
  • the temperature of the reaction can be up to 600 ° C. Reaction temperatures are preferably from 250 to 600 0 C.
  • the reaction gas should usually have a specific gas velocity GHSV 500-5000 h-1 (gas flow in [l / h] / volume of catalyst [I]) have and can at a pressure up to 50 bar Section . be reacted.
  • the formulation of the catalyst is not limited.
  • the catalyst can be used for example as an extrudate, as a powder or supported active material.
