Definitions
- the invention relates to a reactor system with a tubular reactor according to the preamble of independent claim 1.
- Reactor systems with tubular reactors are used, for example, for homogeneous reactions in liquids as they occur in a preliminary stage of vitamin synthesis.
- the reactants have a defined residence time in the reactor and that they are mixed as ideally as possible.
- the reaction conditions are kept constant in a certain range, which e.g. means that heat must be removed in exothermic reactions and heat must be added in endothermic reactions.
- reactor systems with double-wall tubular reactors which comprise a first tube which is arranged coaxially in a second tube.
- the reactants flow through the first (inner) tube at a constant flow rate, so that, with a quasi-ideal mixing, they have a uniform reaction time until they exit the reactor.
- jacketed tubes can be connected in series in a reactor system, so that at a given flow rate of the reactants the residence time required for the reaction in the tube reactor is reached.
- the individual jacketed tubes can be connected to a tube package, for example, by means of tube bends, as a result of which a large reactor tube length can be achieved with a relatively small space requirement.

- the frame can comprise a tripod, the legs of which are arranged in one plane and in such a way that two adjacent legs each enclose an angle of approximately 120 °.
- the tripod can have on each leg from the intersection of the three legs at a distance from the winding radius of the respective coil section, a support arranged at right angles to the tripod, to which the pipe is fastened in the respective coil section.
- a downpipe projecting into the interior of the reactor vessel can be arranged, through which the heat exchange medium supplied to the side of the downpipe and rinsing the tube reactor, e.g. Cooling water can be removed from the reactor boiler.
- the heat exchange medium supplied to the side of the downpipe and rinsing the tube reactor e.g. Cooling water can be removed from the reactor boiler.
- the reactor boiler can be connected to a condenser be so that evaporated liquid heat exchange medium can be removed from the reactor vessel, can be conducted through the condenser and the condensate can be returned to the reactor vessel as a liquid heat exchange medium.

- the frame supports and supports the tubular reactor, which protects it from mechanical stress and damage (vibrations) during operation.
- the tube can be mounted on the frame as a separate unit before being inserted into the reactor vessel, which simplifies the installation and removal of the tube reactor in the reactor vessel.
- the frame can comprise a tripod, the legs of which are arranged in one plane and in such a way that two adjacent legs each enclose an angle of approximately 120 °.
- the tripod can have on each leg, from the intersection of the three legs, at a distance from the winding radius of the respective coil section, a support arranged at right angles to the tripod, to which the pipe is fastened in the respective coil section.

- the four coil sections 201 are arranged one inside the other coaxially around the winding axis 2010 and are connected to the adjacent coil sections 201 via a connecting pipe section 200 , Connections 21 are arranged on the tube 20 at different heights.
- a reaction medium is fed to the tube 20 via a first of the connections 21 and flows through the tube coil regions 201 from bottom to top. Via the vertically arranged connecting pipes 200, the reaction medium is led directly from the upper end of the one pipe coil area 201 to the lower end of the adjacent pipe coil area 201, which in turn flows through it from bottom to top.
