Gas Expander is a powerful, user friendly, program for the analysis of expansion turbines. An expansion turbine (Turboexpander) is a device for converting the energy of a gas or vapor stream into mechanical work as the gas or vapor expands through the turbine.
The expansion process occurs rapidly, and heat transferred� to or from the gas is usually very small. Consequently, the exit temperature of the gas may be
quite low.� This feature allows the expander to find application as a component of refrigeration systems.
The other use of Turboexpanders is in power recovery. When a large flow of gas is reduced from a high pressure to some lower pressure, or when high-temperature process streams are available at moderate pressures, the energy can be recovered
to drive pumps, fans, etc.
