A reaction chamber for a chemical reactor comprises a casing () of the reaction chamber, a floor () of the reaction chamber having an opening () located in the floor, an agitator shaft () located in the chamber and having at least one agitator element (), connected thereto, wherein the agitator shaft (), seen in the longitudinal direction, has a beginning () and an end (). In the opening () of the floor () a removable sleeve () is provided, which projects out of the reaction chamber. The sleeve () is arranged in alignment with the axis of rotation of the agitator shaft (). The internal diameter of the sleeve () is greater than the diameter of the agitator shaft () and the agitator shaft (), at the beginning () thereof and/or at the end () thereof, is adapted to absorb reversibly a torque provided by means of a further shaft and/or to transmit a torque to a further shaft. Using such a reaction chamber, it is possible to build up modular chemical reactors having decreased backmixing.

Reaction chamber for a chemical reactor, and chemical reactor constructed therefrom

The present invention relates to a multistage stirred reactor, comprising a multiplicity of mutually adjacent reaction chambers and stirring elements for mixing the contents of at least one of the reaction chambers, wherein, between adjacent reaction chambers, there is in each case provided at least one opening that can be closed by means of closure means, such that in the open state there is a fluidic connection between the adjacent reaction chambers and in the closed state the adjacent reaction chambers are separated from one another. At least one of the closure means () is connected to an actuation rod () that is guided out of the stirred reactor. The actuation rod () can be moved back and forth between at least one first position and a second position, by rotation and/or displacement, wherein in the first position closure means () that are connected to the actuation rod () effect an open state of the opening assigned to them and in the second position closure means () that are connected to the actuation rod () effect a closed state of the opening assigned to them.

Multi-stage stirred reactor having reduced back mixing

The present invention provides a nozzle plate and the use of the nozzle plate for producing filaments, preferably silica gel fibers.

Method of producing a filament comprising a silica gel-fiber

A production arrangement for performing a chemical reaction with a standard transport container in accordance with DIN ISO 668 for accommodating a plurality of processing units disposed inside the standard transport container for assisting and/or performing a processing basic operation, and a supply network, disposed inside the standard transport container, for supplying the processing units with material and/or power and/or information. Owing to the supply network disposed inside the standard transport container, the availability of material and/or power and/or information can be ensured over a large area of the standard transport container, such that the same standard transport container with the same supply network can be re-used for different configurations of processing units and, in the event of a modification for performing a different chemical reaction, the processing units can simply be interchanged such that different chemical reactions can be performed with little outlay.
