Reliable Instrument Air for Large Facilities
Centrifugal instrument air compressors at large generating stations receive surge prevention and capacity monitoring to maintain the plant-wide pneumatic control air supply.
Context
Challenge & Approach
The Reliability Challenge
Power plant fuel gas booster compressors face surge during rapid gas turbine load changes and fuel switching transients. Pipeline fuel gas composition and pressure variations shift compressor operating points toward surge. Compressors on air separation units require sustained high availability to maintain oxygen supply for combustion systems. Flue gas compressors for carbon capture handle corrosive gas streams containing SO2, moisture, and particulate that foul impellers and corrode internals. Thrust bearing overload during surge events increases axial displacement and risks rotor contact. Anti-surge valve response must be fast enough to protect the compressor during gas turbine trip events.
Our Approach
We perform compressor performance analysis using polytropic efficiency calculations to detect fouling and internal degradation. Surge margin analysis maps operating points across the range of gas turbine loads and fuel compositions. Bearing vibration monitoring with proximity probes provides continuous condition assessment. Anti-surge valve response time testing verifies protection adequacy during transient events. Dry gas seal leakage trending identifies seal degradation. Our deliverable includes a surge prevention strategy for fuel gas boosting service, bearing condition report, anti-surge system performance verification, and a maintenance plan integrated with gas turbine outage scheduling.

Learn More →Compressor fouling deposits on airfoil surfaces reduce the mass flow and pressure ratio the compressor section delivers to the combustor. This directly limits the fuel flow and therefore the power output of the gas turbine. Fouling can reduce power output by 3 to 5 percent or more between washes. Corrected power and efficiency trending quantifies the fouling impact and determines the economic optimum wash frequency based on the cost of generation loss versus the cost of washing.
Gas turbine fuel gas specifications typically address heating value range, hydrogen sulfide content (usually below 20 ppm), moisture content, liquid hydrocarbon dew point, particulate loading, and alkali metal content. Fuel specifications vary by manufacturer and turbine model. Deviation from specifications can cause combustion instability, hot section corrosion, and emissions exceedances. Gas conditioning equipment upstream of the turbine must reliably deliver fuel meeting these specifications.
Large power plants with high instrument air demand (above 500 SCFM) often use centrifugal compressors for their oil-free compression, high capacity in compact packages, and lower specific energy at high utilization. Smaller plants and those requiring high turndown capability typically use reciprocating or rotary screw compressors. The choice depends on flow demand, load variability, air quality requirements, and the economic trade-off between capital and operating costs.
