Definitions
- Mud phase reactions are reactions in which at least one finely divided solid and one liquid phase are involved.
- Mud phase reactors therefore have complex heat exchanger designs in the interior of the reaction vessel, see e.g. US Pat. No. 3,243,268 or EP-A 263 935.
- the heat exchange takes place in that the reaction mass is carried out on so-called "field" heat exchanger tubes or on boilers which are closed on one side and in which the heat transfer medium and the steam formed are conducted in countercurrent , is pumped around.
- the disadvantage is the different flow velocity of the reaction mass in relation to the reactor space and the resulting poor efficiency of the heat exchanger.
- the different flow rate of the reaction mass causes flow-calming zones in which the solid component involved in the reaction can settle.
- the reaction mass is accordingly carried out “inversely” in comparison with conventional evaporative heat exchangers in the heat exchanger.
- the present invention relates to a sludge phase reactor for exothermic sludge phase reactions, which contains the following elements:
- the annular space has a plurality of vertical through-channels with a round cross-section for the reaction mass and the coolant flows through the annular space between the through-channels for the reaction mass.
- the heat exchanger annulus of reaction mass is preferably un
- the passage channels for the reaction mass are flowed vertically upward through the annular space.
- the stirrer is preferably arranged at the lower outlet of the central free flow space and at least one of the reaction components is supplied in the immediate vicinity of the stirrer, so that, on the one hand, the reaction component is rapidly distributed in the reaction mass and, on the other hand, the reaction component supplied with the reaction mass is very high is quickly introduced into the heat exchanger.
- an overflow is provided above the liquid level in the reaction vessel, from which the reacted reaction mass is continuously removable.
- ve vaporizing agent As a heat transfer medium is preferably used ve vaporizing agent, which is supplied in liquid form at the bottom of the heat exchanger annulus and at the top of the heat exchanger Annulus is withdrawn in gaseous form. Water is particularly preferably used as the heat transfer medium and the heat exchange is carried out with the generation of steam.
- the coolant temperature is preferably set by maintaining the pressure of the generated steam.
- the stirrer is designed as a gassing stirrer or has an additional gassing element.
- the sludge phase reactor according to the invention with a gassing stirrer is particularly suitable for carrying out sludge phase hydrogenations of aromatic
- Nitro compounds particularly preferably for the hydrogenation of dinitrotoluenes to produce the corresponding diamines.
- FIGS. 1 and 2 The invention is explained in more detail with reference to the accompanying FIGS. 1 and 2:
- FIG. 1 shows a cross section through the sludge phase reactor according to the invention.
- FIG. 2 shows a cross section AA through the reactor according to FIG. 1.
- reaction vessel 1 consists of a reaction vessel 1 which is constructed from three parts which are flanged together by means of flanges 11 and 12.
- the middle part of the reaction container 1 contains the annular heat exchanger 2, which consists of an annular space which is closed on all sides and one
- the circulating flow of the reaction mass is brought about by the stirrer 4 with a central stirrer shaft 41 and stirrer blade 42 driven outside the reactor.
- the stirring blade 42 is arranged at the level of the exit from the central flow space 3 downwards.
- the stirrer axis 41 is designed as a hollow axis and points below the stirring blade
- the fresh hydrogen supply can advantageously be made directly in the reaction mass.
- the aromatic nitro compound is introduced via feed line 5 in the immediate vicinity of the stirring blade 42.
- the hydrogenation catalyst for example noble metals or nickel on carrier particles such as coal, SiO 2 , Al 2 O 3 etc. or
- Raney nickel catalysts dispersed in the reaction mass.
- the product is continuously drawn off at the overflow 7, so that a constant liquid level is maintained.
- the heat exchanger annulus is also fed from a heat exchange medium circuit 6.
- the heat exchange medium preferably water just below the boiling point, is at 61 in the
- Heat exchanger initiated below Water vapor exits the heat exchanger at the top at 62 and is fed to the steam separator 63.
- Arrow 64 indicates the derivation of the steam for energy recovery.
- the inflow valve for cooling water 65 is controlled by means of a level control 66 for the water level in the steam separator 63.
- the coolant pressure 64 is controlled so that a temperature of 120 to 250 ° C is maintained in the reactor.
- FIG. 2 denote the same elements as in FIG. 1.
- the passage tubes 21 are only partially shown.
- the heat exchanger 2 can
- 100 to 3000 passage pipes 21 have, depending on the nominal size of the pipes (25-10 mm) and diameter of the heat exchanger (up to 3 m).
