140TCH Pipeline Compressor

The 140TCH is a pipeline compressor configuration from Ebara Elliott Energy, designed specifically for long-distance natural gas transmission. It is a gearless, low-emissions unit driven by a direct-coupled high-speed induction motor powered by a variable frequency drive (VFD), with a standard footprint and custom aerodynamics; a standard gear-driven solution is also available. According to the manufacturer, the gearless configuration gives a smaller footprint, lower lube oil requirements and higher net efficiency, and the VFD-powered motor significantly reduces CO2 and NOx emissions compared with a gas turbine. Other features include a high-efficiency axial inlet, single or dual impellers depending on the application, a single-lift skid including auxiliaries, and easy access to the compressor internals for maintenance. The unit is offered from 10 to 35 MW, with the aerodynamic flow path customised to each application.
