Disclosed is a method for supplying current to a reactor, wherein electrode(s) of an electrical energy network (EEN), which is DC-isolated from ground potential, is/are fed through a reactor wall and connected to an electrically conductive element (ECE) so that an operating voltage is applied to the ECE and electrical current flows through it. A seal of electrically insulating material is provided between the wall and the electrode. The EEN is monitored for insulation faults. A fall below a particular insulation resistance triggers shutdown of the electrical energy supply. The switching threshold is determined by taking into account at least one of the following parameters: seal geometry, seal material, supply voltage and maximum possible electrical energy input into the seal immediately before shutdown, triggered by the maximum theoretically possible leakage current through the seal. A device and an electrode having respective seals are also disclosed.

A device for thermal treatment of corrosive gases includes a chamber for heating gases in which there are at least four heating elements or four groups of heating elements including an electrically conductive material, wherein each heating element or group is connected to a separately regulatable and/or controllable subsystem of an electrical energy network and can thereby be heated by direct current flow, wherein each heating element or group can be controlled or regulated with respect to at least one either identical or different value of a parameter selected from the group consisting of temperature, heating power, current, voltage and resistance, or with respect to another heating element process variable, which can be influenced by the device, and wherein at least four regulatable and/or controllable subsystems are DC-isolated from ground potential. The invention also relates to a corresponding method for the thermal treatment of corrosive gases.

Mixtures containing high boiling and low boiling components, at least one component being dissociatable into ions, are separated effectively by heating by passing an alternating electrical current through the mixture. The process is particularly effective in the workup of crude alkylchlorosilanes from the direct synthesis.
