摘要： The present disclosure is directed to systems and methods for direct electrical heating of process heaters tubes (e.g., reactor tubes) using galvanic isolation techniques. The disclosure is also directed to systems and methods for direct electrical heating of process heaters tubes wherein the tubes are galvanically isolated in such a manner as to avoid the use of electrical insulation of the tube from the rest of the system, such as the other tubes, the tube inlet header and/or the tube outlet header, and the reactor shell.

摘要： Methods of heating a reactor system by providing electrical energy are described. A reactor system comprising at least one reactor tube having a catalyst disposed therein and comprises at least one electrically conductive surface is heated by providing electrical energy to the at least one electrically conductive surface on the reactor tube and adjusting a current level of the electrical energy provided to the at least one electrically conductive surface to control the temperature of the reactor tube and the catalyst disposed therein. The reactor tube may be electrically isolated from other electrically conductive components of the reactor system.

摘要： The present disclosure is directed to systems and methods for direct electrical heating of a fluid conduit, also referred to in one form as a tube. A fluid heating system includes a tube defining a fluid passage. The tube includes a material having a conductivity greater than 1.0 Siemens per meter (S/m) at 20° Celsius. The material is distributed along the tube and the fluid passage defines an inlet configured to receive fluid and an outlet configured to release the fluid. The system includes a first power supply, which includes a first circuit. The first circuit is configured to conduct first electric current across a first portion of the tube and the first circuit includes a first galvanic isolator between a source of the first power supply and the first portion of the tube. The first power supply is configured to heat the tube based on the first electric current.
