This is required to prevent erosion damage to the turboexpander.

The system utilizes a compressor, a turboexpander and an electric motor.

By using a turboexpander the electricity needs for compressed storage on 200 bar amounts to 2.1% of the energy content.

Therefore, the vortex tube is a rotorless turboexpander.

The principle of operation is similar to the near isentropic Brayton cycle of a turboexpander.

Figure 5 depicts how power is recovered and utilized by routing the regenerator flue gas through a turboexpander.

Hydraulic brakes are used when the turboexpander is very small and harvesting the shaft power is not economically justifiable.

As shown in Figure 5, expansion of the flue gas through a turboexpander provides sufficient power to drive the regenerator's combustion air compressor.

The Supersonic Gas Separator can in many cases have a 10 - 20% higher efficiency than a Turboexpander.

In 1939, the Russian physicist Pyotr Kapitsa perfected the design of the centrifugal turboexpander.

Figure 3 depicts an electric power generation system that uses a heat source, a cooling medium (air, water or other), a circulating working fluid and a turboexpander.

The Supersonic Separator has a smaller footprint and a lower weight than a Turboexpander or Contactor columns.

Various refrigeration strategies exist: the most economical process presently in wide use employs a Turboexpander, and can recover over 90% of the ethane in natural gas.

The extraction of the NGL often involves a turboexpander and a low-temperature distillation column (called a demethanizer) as shown in Figure 2.

The fuel cell is supplied by FuelCell Energy Inc. of the U.S., and the turboexpander is European.

With centrifugal compressors and electrical generators the shaft power from the turboexpander is recouped either to recompress the process gas or to generate electrical energy lowering utility bills.

Technologies used to achieve these steps are adsorption, absorption, membranes and low temperature systems achieved by refrigeration or expansion through a Joule Thomson Valve or a Turboexpander.

The refrigerant liquid flows through the turboexpander where it is vaporized and the vapor undergoes an isentropic expansion which results in a low-temperature mixture of vapor and liquid.

In effect, the inlet gas provides the heat required to "reboil" the bottom of the demethanizer and the turboexpander removes the heat required to provide reflux in the top of the demethanizer.

The resulting high-pressure vapor flows to the turboexpander where it undergoes an isentropic expansion and exits as a vapor-liquid mixture which is then condensed into a liquid by heat exchange with the available cooling medium.

A turboexpander, also referred to as a turbo-expander or an expansion turbine, is a centrifugal or axial flow turbine through which a high pressure gas is expanded to produce work that is often used to drive a compressor.

Depending on the operating conditions, the turboexpander reduces the load on the electric motor by some 6 to 15% as compared to a conventional vapor-compression refrigeration system that uses a throttling expansion valve rather than a turboexpander.

While expanding, the gas has to do work as it is led through an expansion turbine.

The first phase of the project, which involves a one-megawatt expansion turbine, is under construction.

Modern expansion turbines can achieve efficiencies around 90%.

The air cycle system would directly produce cooling from the expansion turbine thereby reducing the size, weight and increasing the efficiency of combined systems.

In 1939 he developed a new method for liquefaction of air with a low-pressure cycle using a special high-efficiency expansion turbine.

This 8 acre parcel would be ideal and would allow us to close out a potential sound receptor necessary for the expansion turbine.

The fuel-cell and gas expansion turbine plant is the first of its kind in the world and will operate in Toronto.

Modern ASUs use expansion turbines for cooling; the output of the expander helps drive the air compressor, for improved efficiency.

To achieve the required TSFC, the EJ22 turbofan was designed as a three spool engine having a fan, two axial compressors and three expansion turbines.

The usual compression, cooling and expansion seen in any refrigeration cycle is accomplished in the ACM by a centrifugal compressor, two air-to-air heat exchangers and an expansion turbine.

The compressed, cooled air then travels through the expansion turbine which extracts work from the air as it expands, cooling it to below ambient temperature (down to 20 C or 30 C).

When the electricity is needed, which is often during peak hours, the air is withdrawn, heated by the exhaust from a natural gas-fired combustion turbine, and run through expansion turbines to drive an electric generator.

The Honourable Gary Lunn, Minister of Natural Resources, today announced $785,000 for Enbridge Gas Distribution to launch a project using a fuel-cell and gas expansion turbine plant in Toronto.

A turboexpander, also referred to as a turbo-expander or an expansion turbine, is a centrifugal or axial flow turbine through which a high pressure gas is expanded to produce work that is often used to drive a compressor.

The work extracted by the expansion turbine is transmitted by a shaft to spin the pack's centrifugal compressor and an inlet fan which draws in the external air for the heat exchangers during ground running; ram air is used in flight.
