Pipe heat-tracing with electric impedance heating

As the world's reserves of oil and natural gas dwindle and the sources of supply become less dependable, industry must find alternative sources of energy for its survival. One solution is electricity, in particular impedance heating, which provides a simple, efficient, reliable, and accurately controllable method of heating fluids in a pipe. The principles of impedance heating are discussed as are its advantages. The complicated engineering of installing an impedance heating system into a plant is explained.
