Scrubbing Function

Pipeline gas contains iron oxide scale, pipe debris, compressor oil carryover, condensed hydrocarbons, and trace H₂S affecting combustion quality and equipment reliability. Scrubbers remove solids through filtration, separate liquids via coalescence, and absorb acid gases using chemical media ensuring fuel meets turbine manufacturer specifications and emissions limits.

Vessel Design

Vertical configuration with inlet distributor, filtration stages removing particles above 5-10 microns, coalescing section separating liquid droplets, optional chemical media bed absorbing H₂S, and outlet section with mist eliminator. ERGIL sizes scrubbers based on gas flow rate, contaminant loading, and required outlet quality.

Filtration Technology

Cartridge filters capture rust, scale, and solid particles protecting turbine fuel nozzles from erosion and plugging. Coalescing elements remove oil mist and hydrocarbon droplets. Chemical adsorbent beds reduce H₂S to below 0.5 ppm meeting turbine fuel specifications. Replaceable elements enable maintenance without vessel removal.

Applications

Gas turbine fuel conditioning for power generation, industrial boiler fuel cleaning, reciprocating engine fuel treatment, process heater fuel gas, and any combustion application requiring contaminant removal. Serves power plants, refineries, chemical facilities, and manufacturing operations with flow rates 1,000-100,000 SCFH.

Control Features

Differential pressure monitoring across filter elements indicates loading requiring replacement. Liquid level switches activate automatic drains. Temperature monitoring ensures proper operating conditions. Integration with fuel gas systems enables automated operation with minimal supervision.
