High-Pressure Operation

Gas turbines require fuel at pressures matching combustor conditions typically 300-600 psig for industrial turbines and up to 1500 psig for aero-derivative units. HP scrubbers operate at supply pressure removing contaminants before final pressure regulation preventing fouling of expensive fuel control valves, nozzles, and combustion hardware.

Vessel Design

Vertical pressure vessel with multi-stage filtration including coarse strainer removing large debris, cartridge filters capturing particles above 5 microns, coalescing elements separating liquid droplets and oil mist, and optional chemical media for H₂S removal. Heavy-wall construction handles high operating pressures. ERGIL sizes scrubbers based on turbine fuel demand and pressure conditions.

Filtration Performance

Removes iron oxide scale, weld slag, pipe debris from transmission lines, compressor lubricant carryover, condensed hydrocarbons, and water protecting turbine fuel systems. Achieves outlet cleanliness meeting turbine manufacturer specifications typically 5-10 micron particle size. Coalescing stages reduce liquid content preventing fuel system icing and combustion issues.

Material Selection

Carbon steel or stainless steel construction with heavy wall thickness for high-pressure service. Materials per ASME Section VIII Division 1 or Division 2 for extreme pressures. Filter housings accommodate element replacement under pressure isolation. Design includes proper corrosion allowances and impact testing where required.

Applications

Gas turbine fuel conditioning for power generation and mechanical drive, high-pressure industrial burner fuel treatment, pipeline compressor station fuel supply, and any high-pressure combustion requiring clean fuel gas. Serves facilities with fuel demands 5,000-500,000 SCFH at elevated pressures.

Control Features

Differential pressure monitoring across filter stages indicates element loading. Automatic liquid drains remove coalesced condensate. High differential pressure alarms signal maintenance requirements. Integration with turbine fuel systems enables coordinated operation and monitoring.

Performance Benefits

Protects expensive turbine hardware from erosion, corrosion, and fouling. Maintains fuel system reliability reducing unplanned outages. Extends filter element life through staged filtration. Heavy-duty construction ensures safe high-pressure operation. Proven technology in critical power generation applications.

Construction Standards

Design per ASME Section VIII with appropriate division for operating pressure. Materials rated for high-pressure fuel gas service. Electrical systems for hazardous classification. Relief valve protection sized per API 520. Complete documentation with design calculations and material certifications.

ERGIL HP fuel gas scrubbers deliver dependable high-pressure contaminant removal ensuring clean fuel supply protecting gas turbine investments and maintaining reliable power generation.
