Elements of Fuel Gas Treatment

Pressure Reduction

• Sliding Stem Valves with Positioners

• Reduces the pressure of the gas from 700-1000 psi to 400-450 psi

• Protects Turbine• Improves Turbine

Efficiency

Performance Heater• Shell and Tube Heat

Exchanger– 100% of Gas Flow– Heats Gas to ~350 °

• Boiler Feed Water• Controlled by Throttling

Water Discharge

Start-Up Heater

• Electric Heater– ~25% of Gas Flow– 50 F Temperature Rise

• 50 F Above Dew Point• SCR or Step Control

Water Bath Heater• Gas Fired Heater

– 100% of Gas Flow– Heats Gas to ~180 °

• U-Bend• Controlled by Throttling

Gas Flow/Bypass

Flow Measurement

• Individual Turbine Flow Measurement– Orifice Meter

• Custody Transfer– Not Clark-Reliance
