Embodiment Construction

[0054] Figure 1a and Figure 1b Shown is a tube bundle reactor 1 with a reactor main part 2 , an external heat carrier pump 3 , an external main heat exchanger 4 and an external secondary heat exchanger 5 .

[0055] The reactor body part 2 has a cylindrical reactor cover 6, which surrounds ( Figure 1b Not shown in ) a bundle of vertical reaction tubes 7. The reaction tube 7 is hermetically fixed in the upper tube base 8 or the lower tube base 9 at both ends thereof. The reactor housing 6 and the tube bases 8 , 9 together form a housing chamber 10 in which the reaction tubes 7 are circulated by the heating medium 11 . In the illustrated embodiment, the reaction gas 12 flows through the reactor tube 7 from top to bottom.

[0056] Reactor caps 13 , 14 extend on the two tube bases 8 , 9 , in the exemplary embodiment shown, on the upper tube base 8 as gas inlet cap 13 and on the lower tube base 9 as gas outlet cap 14 . The reaction tube 7 is open at the end and is in flow con...

Abstract

The present invention relates to a tube bundle reactor which is used for catalytic gas phase reaction. The tube bundle reactor is provided with the following components: a bundle of reaction tubes surrounded by a cylindrical reactor shell, which forms a shell space, in which the reaction tubes are immersed by a heat carrier, where the reaction tubes are traversed by a reaction gas; a heat carrier-annular flow channel and a heat carrier-annular return channel, which encloses the reactor shell in a respective end region of the cylinder and which is in flow communication with the shell space via many casing openings, where at least the annular return channel is free of sub-channels; an external pump whose inlet is connected to the heat carrier-annular return channel and the outlet is connected to the heat carrier-annular flow channel, where the heat carrier circulates in a circuit through the annular flow channel, shell space and the annular return channel. The tube bundle reaction can improve efficiency of the external pump through optimization of the pump which supports flow through of the heat carrier.

Description

technical field [0001] The invention relates to a tube bundle reactor (Rohrbuendelreaktor) for catalytic gas phase reactions, which has: bundled reaction tubes, which are surrounded by a cylindrical reactor cover, the reactor cover forming a cover cavity (Mantelraum), in In this case, the reaction tube is circulated by the heating medium, wherein the reaction tube is flowed through by the reaction gas; in addition, there is a heating medium-forward annular channel (Vorlaufringkanal) and a heating medium-returning annular channel (Ruecklaufringkanal), which are corresponding in The column surrounds the reactor housing in its end region and is in flow connection with the housing chamber via a large number of housing openings, wherein at least the return annular channel has no sub-channels (Unterkanal); and has an external pump whose inlet is connected To the heating medium-return annular channel and its outlet is connected to the heating medium-forward annular channel and it cir...
