Problems solved by technology

[0022] But this method has the disadvantage that the reaction in the heat pipe may burn out only due to the reduced flow, although the reactions in all other reaction pipes proceed normally
This reduces the practicality of
Also, there is no information on the temperature between the individual thermometers within the STM
The representativeness of the temperature curve obtained in this way is poor

Embodiment Construction

[0092] The embodiment of the tube bundle reactor 1 shown in the figure has a bundle (not shown) of reaction tubes, at least one heat pipe 2, an upper tube base 3 and a lower tube base 4, a housing 5 , a gas inlet mouth 6 and a gas outlet mouth 7 and a mechanical positioning device 8. In the exemplary embodiment shown, the gas inlet hood 6 is the upper reactor hood and the gas outlet hood 7 is the lower reactor hood; they will also be referred to as such below.

[0093] figure 1 A multi-stage thermometer (STM) 9 in the KAT heat pipe 2 a of the tube bundle reactor 1 is schematically shown together with the mechanical positioning device 8 . For clarity, the reaction tubes are not shown, only one KAT heat pipe 2a is shown enlarged. The reaction tubes and heat pipes 2 are cooled by the heat transfer medium 10 of a heat transfer medium system (not shown here), which has a circulation pump, a cooler, a heater, reversing plates and also other components.

[0094] In this example, a...

Abstract

The present invention relates to a tube bundle reactor for carrying out endothermic or exothermic gas phase reactions, comprising a tube bundle of reactor tubes filled with catalyst, having their ends fastened tightly in tube sheets, a fluid heat carrier flowing around the tubes during operation, a shell enclosing the tube bundle, a gas inlet head spanning one of the tube sheets, a gas outlet head spanning the other tube sheet, the reactor tubes being in fluid communication with the gas inlet and outlet heads, further comprising at least one stage thermometer installed in a thermometer tube disposed in the tube bundle, the at least one stage thermometer is axially movable inside the thermometer tube, and the tube bundle reactor comprises a mechanical positioning means to effect the axial movement of the stage thermometer. Moreover, a method is proposed for measuring a temperature profile in tube bundle reactors of the kind specified.

Description

technical field [0001] The invention relates to a tube bundle reactor according to the preamble of claim 1 . The invention also relates to a method for measuring the temperature profile in such a tube bundle reactor. Background technique [0002] For heterogeneously catalyzed gas phase reactions such as oxidation, hydrogenation, dehydrogenation, nitration, hydrocarbylation processes, in particular tube bundle reactors have proven to be a particularly good design for fixed bed reactors in the chemical industry. Such a tube bundle reactor is known, for example, from DE 2 207 166 A1. A tube-bundle reactor comprises a reactor main part with a vertically arranged bundle of reaction tubes, in which reaction tubes usually contain catalyst in granular form and possibly also inert materials. The reaction tubes are fastened at their ends in a sealing manner in the upper and / or lower tube base. The tube bundle is surrounded by the reactor shell. The reaction can be endothermic or e...
