A fuel conditioning system for conditioning natural gas fuel provided by a pipeline for use with at least one natural gas fuel powered turbine, the fuel conditioning system comprising:
- an inlet metering station having an inlet flow meter to measure natural gas fuel flow from the pipeline;
- an inlet pressure control station having an inlet pressure monitoring instrument and an inlet pressure regulator, the inlet pressure regulator controlling the pressure of the natural gas fuel provided by the pipeline;
- an inlet scrubber station having an inlet vertical centrifugal scrubber and an inlet scrubber level control valve, the vertical centrifugal scrubber removing liquids from the natural gas fuel provided by the pressurized pipeline and the inlet scrubber level control valve releasing the removed liquids from the scrubber;
- an inlet filter station having an inlet filter and an inlet filter level control valve, the inlet flow filter removing aerosols and particulates from the natural gas fuel provided by the pressurized pipeline and the inlet filter level control valve releasing the removed aerosols and particulates from the inlet filter;
- a turbine distribution system for receiving natural gas fuel which has passed though the inlet pressure control station, the inlet scrubber station and the inlet filter station;
- at least one turbine pressure control station receiving natural gas fuel from the turbine distribution system, the turbine pressure control station having a turbine pressure monitoring instrument and a turbine pressure regulator, the turbine pressure regulator controlling the pressure of the natural gas fuel received and controlling pressure changes in the natural gas fuel received;
- at least one turbine super-heater station receiving natural fuel gas from the turbine distribution system, the turbine super-heater station having turbine super-heater monitoring instruments to determine the dew point of the natural gas fuel and the dew point of hydrocarbons in the natural gas fuel, the super-heater station further having a heater to heat the natural gas fuel gas above the dew point of both moisture and hydrocarbons found in the natural gas fuel, and at least one heater control valve to limit changes in the temperature of the natural gas fuel;
- at least one turbine filter station having a turbine filter and a turbine filter level control valve, the turbine filter removing aerosols and particulates from the natural gas fuel and the turbine filter level control valve releasing the removed aerosols and particulates from the turbine filter;
- at least one trip transient mitigation system having a surge vent valve;
- at least one turbine fuel accessory unit having fuel accessory unit monitoring instrument to measure the pressure, the temperature, or the volume of the fuel gas and a speed ratio valve, the fuel accessory unit monitoring instrument communicating with the speed ratio valve to close the speed ratio valve when the fuel accessory monitoring instrument measures a pressure, a temperature, or a volume outside of an acceptable range;
- and
- a programmable logic controller associated with and receiving data from the inlet flow meter, the inlet pressure monitoring instrument, the inlet scrubber level control valve, the inlet filter level control valve, the turbine pressure monitoring instrument, the turbine super-heater monitoring instrument, the turbine filter level control valve, and the fuel accessory monitoring instrument, the programmable logic controller also associated with, and providing control commands to, the inlet pressure regulator, the turbine pressure regulator, the heater, the heater control valve, and the surge vent, the control commands based upon the data received and control algorithms.
