NGSG SMART System Highlights:

  • Reduce shutdowns by as much as 25% over industry standard compressors*
    • 100% turn down of flow - 24/7/365
    • Elimination of pressure, horsepower, and rod-load related shutdowns
    • Rock-solid pressure control over the widest range of process needs & upsets
    • Robust freeze avoidance for uninterrupted operation in cold weather
    • Run through fluctuating BTU fuel gas upsets rather than shutting down
  • Maximum power and flow optimized over the entire range of process conditions – done automatically
  • When N+1 units are installed, compressor flow reliability approaches 100% as the multiple machines automatically increase flow to fill gap when unit goes down
  • Dewpoint control – temperature process control to within 2-4°F of setpoint
  • Telemetry via cellular or satellite of package data (includes ALL engine panel information too):
    • Remote setpoint allowable
    • Monthly sorting and tally of alarms/shutdowns for continuous improvement
    • Both customer connection at panel and web-based access to real time and historical data

Package Build Features:

  • All vessels compliant with ASME Section VIII standards with 1/8" corrosion allowance
  • All vessels compliant with API 11P Class C standard
  • All piping systems meet ASME B31.3 standard
  • API 618 Design Approach 2 pulsation and mechanical analysis performed for smooth operations
  • Standard design to maximize parts availability and minimize downtime
  • Suction control and recycle valves - Murphy CS controller. Recycle valve is mounted on skid
  • Inlet strainer with break out valves - DP pressure monitoring through controller for alarm/clean
  • DP pressure and temperature monitoring across exhaust catalyst
  • Rigid four beam skid with 1.5 times capacity environmental containment designed to mount on packed earthen pad

Driver:

  • NGSG custom knock out fuel gas scrubber for maximum engine protection
  • Electrical rating service of Class 1, Group D, Division II areas*
  • NGSG custom designed, Murphy CS controlled inner and outer louvers, separate for each process gas section – These louver sections do not require frequent adjustments and repairs like industry standard louvers
  • No hot gas bypass required
  • NGSG custom flooded skirt heat tracing to avoid package liquid line freeze ups
  • Critical grade engine exhaust silencer
  • Murphy CS controller–fully integrated with engine messages and alarms
  • Cold weather starting capability - Kim hot start for oil and jacket water (option)
