Turbo expanders TFC was developed with a cold (cryogenic) compressor on the same shaft as well as an additional oil brake to extract energy from the process.
Turbo expander TFC allow a very flexible operation as the turbine power can be dissipated via an oil brake and an optional variable diffuser allows a wide range of compressor flows.
Typical Application:
Industrial gas industry (air separation units) to provide refrigeration when a process cryogenic booster compressor is required with adjustable cold power provided by the oil brake.
Usual Gases Handled: air, nitrogen, waste gas from air with high oxygen content.
Pressure | up to 70 bar |
Flow | up to 150 000 Nm³/h (50 kg/s) |
Expander temperature | - 196 °C for expander and compressor |
Power generated by the expander | up to 2000 kW; up to about 300 kW of refrigeration through its oil brake |
