Device for conducting a chemical reaction in a process fluid in a production facility

An apparatus for carrying out a chemical reaction in a process fluid in a production system having at least one ground connection connected to ground for grounding production system components, comprising:

• a reactor, comprising one or more reaction tubes which are guided into the reactor and out of the reactor via at least one feed section and at least one discharge section, each reaction tube comprising at least one electrically heatable tube segments which is/are connected to one another in a current output area by an electrically conductive star bridge;
• and
• at least one power source configured to provide a multiphase alternating current with N phases to N phase lines at a predetermined voltage, wherein Nis an integer greater than or equal to 2, and wherein for each two phases, a phase shift between the two phases is 2π·k/N, where k is in each case an integer in the range of 1 to N−1;
• wherein;
• for each of the at least one power source, a number N of power connections is provided, each of which is connected to a respective tube segment in a current input area, wherein each of the power connections is connected to one of the phase lines of the power source;
• in the at least one power source, a star point is formed at which the phase lines of the power source are connected;
• and
• the star point is not connected to a ground connection.
