Clark Reliance Corporation Strongsville, OH

Fuel Gas Treatment

Applications From Well to End User

Gas Gathering • Multiple Wells to Production • Remove Solid and Liquid Contaminates • Robust Mechanical Separation • Minimal Maintenance • H 2 S and CO 2 is removed as well.

Gas Transmission • Gas Transmission Stations • 50 to 100 Miles along the Pipeline • Compressors Increase Pressure for Further Distribution • Inlet - Separators, Filter Separators • Outlet – Coalescing Filter

Combined Cycle Electrical Generation Process Overview • • • Generate Electricity for Power Grid Peak Power Generation Base Load Produce Steam Drive Steam Turbine for Additional Power Generation

Elements of Fuel Gas Treatment • Pressure Control • Temperature Control • Flow Measurement • Removal of Impurities – Knockout – Fine Filtration – Last Chance Filter

Pressure Reduction • Sliding Stem Valves with Positioners • Reduces the pressure of the gas from 7001000 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 • 50 F Above Dew Point – ~25% of Gas Flow • SCR or Step Control – 50 F Temperature Rise

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

Removal of Impurities Mechanical Separation Filtration

Gravity Separation • Vane Separators • KO Drums • 100% Removal of >8µ Liquids

Gravity Separation • Offset inlet with baffle • Handles slugs of liquids • Efficiency to 100% down to 5 micron liquid particles

Centrifugal Separation • Gas-Liquid Separation • HI-EF Element • 99 -100% Removal of Liquids to 8µ Solids to 5µ

Centrifugal Separation • Multi-Cyclone • Scrubber • 99 -100% Removal of Liquids to 8µ Solids to 5µ • Limited Turndown in Gas Flow

Filter Separator • Multi-Stage • Liquid and Solid Filtration • 99% Removal of Solids to 0. 5µ • 100% Liquid and Solid Removal to 3µ

Filter Separator

Coalescing Filter • Optimum Protection • 99. 98% Solid and Liquid Removal to 0. 3µ • Aerosol Removal • Multi-Stage Design • Inside-Out Filtration

Filter Arrangement • • Horizontal or Vertical? Filter or Coalescer? Footprint Access to Filter Elements

Combination Separators • Filter Elements First or Last? • Filter or Coalescer? • Purpose for Mechanical Stage? – Coalescer - Reduce Load on Filter – Filter Sep – Remove Accumulated Liquids and Solids

Filter Elements • Pleated Filter Elements • Melt Blown Filter Elements • Resin Bonded Filter Elements • Coreless Filter Elements • Fiberglass Filter Elements • Membrane Filter Elements

Filter Separator Coalescing Filter • Over 4 times the filtration area • Longer element life • Fewer element changes • More rapid liquid drainage • Lower saturated pressure drop

Filter Access Options • Blind Flange and Davit • Simple • Cheap • Slower Access • Good for Smaller Vessels

Filter Access Options • Sentry • High Pressure • Modco • Screw Type • Low-Medium Pressure
