Abstract

A reactor system ( 1 ) having a reactor 3 , at least one cooler ( 5 ) connected to the reactor ( 3 ), at least one pump ( 7 ) for circulating at least some of a liquid heat-transfer medium ( 9 ), wherein the pump ( 7 ) is connected to the reactor ( 3 ) and/or the at least one cooler ( 5 ), and a container ( 11 ) for collecting the liquid heat-transfer medium ( 9 ) is provided. The container ( 11 ) is connected to the reactor ( 3 ) and/or the at least one cooler ( 5 ) and is disposed substantially below the reactor ( 3 ) and/or the at least one cooler ( 5 ). Also provided are exothermic reactions which are conducted in the reactor system.

First claim

The invention claimed is:

1. A reactor system, comprising:
a reactor;
at least one cooler connected to the reactor;
at least one pump for circulating at least some of a liquid heat-transfer medium, wherein the pump is connected to the reactor or the at least one cooler; and
a container for collecting the liquid heat-transfer medium, wherein the container is connected to the reactor or the at least one cooler,
wherein
the container is connected via outlet lines to a lowermost point of the reactor or the at least one cooler, respectively,
the container is disposed below the reactor or the at least one cooler, and at least partly below ground level, and
a volume of the container is 10% greater than a volume of the liquid heat-transfer medium theoretically contained in the reactor and the at least one cooler.

2. The reactor system according to claim 1 , wherein the container comprises a heating apparatus for heating the liquid heat-transfer medium.

3. The reactor system according to claim 1 , wherein the container further comprises a pump.

4. The reactor system according to claim 1 , wherein the container is connected to both the reactor and the at least one cooler via at least one return line.

5. The reactor system according to claim 4 , wherein the outlet lines or the return line each comprise a heating apparatus.

6. The reactor system according to claim 1 , wherein
the reactor is a shell-and-tube reactor for carrying out exothermic reactions or
the at least one cooler is a salt-bath cooler and the liquid heat-transfer medium is a salt melt.

7. A method for an exothermic reaction, the method comprising:
carrying out the exothermic reaction in the reactor system according to claim 1 .

8. The reactor system according to claim 1 , wherein the cooler comprises an emergency relief port and a safety device.

9. The reactor system according to claim 8 , further comprising a separator arranged downstream of the safety device and a pipe.
