Problems solved by technology

However, the device proposed here has the disadvantage of being inconvenient to use, and said device is also operated by means of compressed air, which additionally makes installation difficult
First and foremost, however, the transport of heavy filled replaceable pods presents no small safety risk, as the pods may fall through the manhole and injure the filling personnel

Embodiment Construction

[0014] A key aspect of the invention is that the filling material 3 is conveyed by means of at least one hose 5a or at least one pipe 5b into the interior space 8 of the shell and tube reactor 2 in order to fill the reactants present therein by means of the filling device 4 Tube 12. The charging system 1 required for this therefore consists at least of a charging device 4, a hose 5a or at least one pipe 5b, the hose 5a or the pipe 5b having an outer end outside the shell-and-tube reactor 2 6 and the inner end 7 in the inner space 8 , wherein the at least one hose 5 a or the at least one tube 5 b is suitable for conveying the filling material 3 into the inner space 8 . To this end, the filling material 3 is introduced into the at least one hose 5a or the at least one tube 5b at the outer end 6 located outside the shell and tube reactor 2, so that the filling material 3 is then The at least one hose 5 a or the at least one tube 5 b exits through the inner end 7 in the interior ...

Abstract

The invention relates to a loading system for introducing a filling material such as an annular catalyst body into a tubular reactor, wherein the loading system comprises a filling device. The invention is characterized in that the loading system comprises at least a host or at least a tube which has an outer end part outside the tubular reactor and an inner end part in the inner space of the tubular reactor and is suitable for conveying the filling material to the inner space through an opening in the tubular reactor. The invention also relates to a method for filling the tubular reactor by using the loading system. The method includes the steps of: a) filling an external front room of which a box can be exchanged with a defined amount of the filling material; and b) introducing the filling material into the at least one host or at least tube which introduces the filling material to the inner space through the opening.

Description

technical field [0001] The invention relates to a charging system for introducing packing material, such as annular catalyst bodies, into a shell-and-tube reactor, wherein the charging system has a filling device and is characterized in that the charging system comprises at least one flexible tube or at least one tube, said at least one hose or at least one tube has an outer end outside said shell-and-tube reactor and an inner space in said shell-and-tube reactor The inner end is adapted to deliver packing material into the inner space through an opening in the shell and tube reactor. Background technique [0002] Shell-and-tube reactors are reactors used in the industrial catalytic oxidation of hydrocarbons, for example, in the production of phthalic anhydride by catalytic gas-phase oxidation of o-xylene and / or naphthalene or in the production of phthalic anhydride by catalytic gas-phase Reactor used in oxidation of butane to maleic anhydride. To this end, a catalyst suit...
