Turboexpanders coupled to generators can be used to generate clean electricity in many different applications. Producing up to 15MW of clean electricity, they can also provide the necessary temperature or pressure drop required in certain processes. The ability to operate efficiently with over 40% liquid by mass at the expander outlet make them viable in applications where the superheated steam conventional turbines require is not available. They are also highly efficient, with isentropic efficiencies over 90% and extremely reliable, with availability factors approaching 99%.
Geothermal energy is a rapidly growing industry as environmental concerns about other power generation techniques capture the attention of governments and the public. Unlike other renewable energy sources, such as wind and solar, geothermal energy has the advantage of stable operation independent of the time of day or the weather, making it an important part of a well balanced renewable energy portfolio. The exploration phase for high temperature applications requires much more capital investment and risk, and millions of dollars can be spent investigating a site only to find that it is not hot enough to produce dry steam needed to drive normal axial multi stage turbines. Low temperature (under 175 degrees Celsius) geothermal sites are much more common than high temperature sites that can produce sufficient quantities of dry steam to drive a conventional turbine or hot brine fluid for the ORC energy recovery. It is predicted that use of low temperature sites using Binary cycles will increase as demand for geothermal energy increases.
Binary cycles use the hot water from the geothermal well to heat a working fluid such as isobutane via a heat exchanger. The working fluid is then expanded through a turbine that drives a generator, producing electricity. A condenser and pump complete the cycle. Because of the smaller temperature ratios that Binary cycles are used for, little energy is available for expansion before condensation begins. Thus, radial expansion turbines, which can operate at lower vapor qualities than conventional turbines, are the ideal prime mover in Binary cycle applications.

CGT series turbine gas meters are flow meters designed to measure quantity of gases. The meters are mainly used for gas flow ranges from 6.5 up to 6500 m3/h. The CGT series gas meters are applied in measurement systems where high accuracy is required:
transportation of natural gas
primary and secondary measurements
control metering of the natural gas and non aggressive technical gases in industry
flow measurement for technical purposes
The meters may be applied for measurements of aggressive gases. Any application of that kind should be individually proved and agreed between the client and COMMON S.A.
The turbine gas meter measures the quantity of gas basing on the flow principle. The gas flows through an integrated flow conditioner, which distributes the flow proportionally in the annular slot and guides it to the turbine wheel. The wheel is driven by the gas flow, and the angular velocity of the rotation is proportional to the gas flow rate. The energy consumption, perceived as pressure loss, is reduced to absolute feasible minimum due to the application of the flow conditioner, highest precision ball barings, most accurate tolerances of all measuring parts and their proper alignement. The rotary motion of the turbine wheel is transferred mechanically by gear wheels, and the incorporated gas tight and hermetic magnetic coupling, to the index unit, which is mounted on the top of the body, and shows the operating volume on the totalizer.
The basic components of the COMMON CGT series turbine gas meter are as follows:
pressure resistant meter body
inlet flow conditioner
measuring cartridge with the turbine wheel
magnetic coupling as the transferring element between measuring cartridge and the index
lubricating system (some meters are provided with self lubricating bearings)
