It is installed using industry-standard flanges. Feed piping may be flanged up or down to that size. The generator is CRN (Canadian Registration Number)-certified to operate at its rated pressures, and each unit is hydro-tested at the factory. All materials used in the construction of the IPTG are NACE (National Association of Corrosion Engineers)-compliant for use in the presence of sour gas (H2S).
Magnetic flux generated by the rotation of magnets within the IPTG produces electric current in coils mounted around the exterior of the pipe. The generator outputs electric power through an umbilical cable to its control box that is conveniently mounted near the batteries and SCADA system.
The generator is designed to withstand the challenging conditions of natural gas well sites. Gas flow that includes water, sand, ice, oil, hydrogen sulfide, or various particulates will not harm the generator. The coils are completely isolated from the natural gas within the pipe and the surrounding atmosphere. The Tazman Turbinz Generator is certified for hazardous location (Class I, Division 1) applications under Canadian Standards Association (CSA) and other applicable standards.
