What is a turbo expander

Expert assessments show that in the current century the role of natural gas in the energy sector of most countries will increase. At the beginning of the thirties of the XXI. In the 19th century, gas consumption could easily double. In order to solve the problem of energy saving in transportation systems, energy recovery systems are increasingly being used, one of which is a turboexpander.

How does the turbo expander work

Utilizing energy resulting from the surpluspressure in the gas transmission system is one of the important tasks that are solved in the gas industry. For this purpose, special expansion turbines are used that are mechanically coupled to a power consumer - a compressor or an electrical generator. One such energy consuming device that does not consume fuel is called a turboexpander. The turboexpander is a gas turbine designed to operate with gas pressure drops. Generators, compressors and pumps are connected to the widest turbine. In this complex system, the turbo expander performs the central function and is its "heart".
One of the technical tasks that Turboexpander's designers are working on is to get rid of the vibration that is destroying the device.
The basis of the turbine is the principle of gas expansion in the working device. The gas flows its energy through the impeller. This significantly lowers the temperature. The energy released can be used to compress the gas in the compressor or to run the power generator. In the latter case, the turboexpander not only provides comparatively cheap electrical energy, but also generates cold.

Use of turbo expanders

Turbo extruders are used in cryogenic installations. They are also used successfully in air separation equipment and in the liquefaction of pressurized nitrogen. Without an expansion turbine, it is difficult to imagine a modern natural gas processing company today.
The turboexpander is actually a source of cheap and clean energy.
The main application of the turboexpander is in the gas industry, where the role of the equipment plays for the expansion of gas. In the turbine there is a process of energy conversion, the amount of which is directly related to the power capacity of the gas flow. Using turbo expanders can take advantage of the excess energy generated when pumping gas through manifold stations. Turbodetanders are actively used in the commissioning of gas turbine systems and turn the rotors of machines in order to cool them. A decrease in gas temperature is also required in plants where it is liquefied and also when the gas product is provisionally prepared for transport and excess moisture is removed by freezing.
