Compressor Station Process Skids

compressor station process skid

S-Con, Inc. provides a modularized process skid option to consolidate ancillary compressor station equipment.

To do this S-Con has taken equipment that is typically block mounted off skid and re-designed it as a modular skid package. Below are a few examples of what is included on one of these skids.

  • Low Pressure Inlet Separation
  • Dehydration of the high pressure discharge gas
  • Coalescing of the dehydrated overhead gas
  • High Pressure Discharge Separation
  • Fuel Gas Separation
  • Inlet and Discharge ESD systems
  • Recycle Control

For fuel gas, a slip stream is taken off of the overhead from the Glycol Contactor and routed through two Big Joe regulators or one EZ-body control valve dropping the pressure down to around 150 PSIG. This pressure drop allows any of the heavier components to drop out in the downstream fuel gas scrubber. The overhead from the fuel gas scrubber is used as fuel gas to run the compressors, any onsite direct fired reboilers or heater treaters and to power any onsite generators that are being used for instrument air or starting air purposes.

A slip stream is also commonly installed off the discharge of the process skid where a client can flow to a sales pipeline and simultaneously run lift gas back to upstream facilities for improved recoveries in the formation.

The S-Con, Inc. Compressor Station Process Skid is designed with the jumper lines for one compressor coming off of the broad side of the skid. A header extension skid can be added to the end of the main process skid for each additional compressor needed at the facility.

The cost of on-site labor and materials is very high, which makes the shop fabrication of these modules very advantageous for cost conscious up stream companies.

Design Specs:

  • The foot print is approximately 14’W X 50’L
  • Weight is typically between 50,000-80,000 lbs. dry.
  • High Pressure Systems are designed to 1420 PSIG @ 130°F
  • Low Pressure Systems are designed to 150 PSIG @ 130°F
  • Fuel Gas is typically provided between 100-140 PSIG. This depends on whether or not the client is having to use starting gas on their compressors.
