Definitions
- the present invention relates to an improved method for cooling a reactor in which an exothermic reaction takes place, wherein within the reactor a heat exchanger dissipates heat produced by means of evaporative cooling.
- the reaction media present in this case within the reactor can be, for example, gaseous, liquid, gaseous and liquid, liquid with suspended solids or gaseous and liquid with suspended solids.
- the reactions can be carried out continuously or batchwise.
- the invention relates to a device for carrying out the method.
- reactors are used to maintain the desired temperature ranges when carrying out exothermic reactions, which allow an internal or external heat dissipation.
- reactors with internal heat removal are tube-bundle reactors or reactors with built-in cooling coils, tube registers or plate heat exchangers.
- the heat of reaction can be dissipated by circulation and recycling of the reaction medium, the cooling can be done by externally mounted heat exchangers of different types. From a reaction engineering point of view, preference is given to reactor designs with internal cooling, since they allow a more precise maintenance of the desired reaction temperatures.
- Another measure to reduce the investment costs is the replacement of the tube bundles against heat exchanger plates. This design allows lower investment costs. Also for the design with heat exchanger plates is the technically and economically possible maximum pressure level for the generated steam at about 100 bar.
- the effectiveness of the method according to the invention and the enlargement of the temperature difference made possible here are predetermined by the prevailing general conditions, such as the design of the heat exchanger, type of porous structuring, heat of reaction to be dissipated, and safety-related maximum wall temperatures to be observed, and can be clarified experimentally by a person skilled in the art.
