A Gas Expander-Generator is used to represent a gas expansion turbine coupled to an electric generator. The equipment resource hosts a Power Generation in a Gas Expander-Generator Procedure with a main objective to expand high pressure gas to low pressure gas and convert delivered shaft power into electrical power.

Sizing: Design Mode

In design mode, the software will size the unit based on the demand on power by the gas expansion operation executed in the unit. If the power exceeds the specification for the maximum power then the software will assume multiple number of identical units (each with power equally distributed) that are operated in parallel.

Sizing: Rating Mode

In rating mode, the power and the number of units are provided by the user.
