Fuel gas package is the gas conditioning process to deliver fuel gas to some level of cleanness and pressure and temperature to meet with operating and design criteria of the main Gas user (Gas Turbine/GT).

The Fuel Gas Package is divided into 5 sections: emergency shutdown valve, Knock Out drum, gas filter separator, fuel gas heater, pressure reduction system for the Fuel Gas Package at 50 Mw Qeshm Power Plant.
