JT Skid Plants & Processing Services

To produce an immediate processing upgrade to your natural gas stream, TransTex has a fleet of JT Skids of various sizes that are readily available and skid-mounted for quick installation.  Our processing plants can increase your NGL recoveries by a pressure drop, condensing and removing ‘heavy’ hydrocarbons.  TransTex has a readily available fleet of 1-20 MMSCFD JT Skids rated at 1440 psig.

What are JT Skids?

JT Skids can serve multiple purposes in the mid-stream value chain:

  • Increase the recovery of valuable natural gas liquids (NGL). By removing the heavier components such as propane or butane, the producer achieves an immediate processing upgrade, increasing recoveries, and profits
    In order to meet the pipeline temperature specifications, producers often lower the British Thermal Units (BTU) with a JT Skid assembly.
  • JT Skids can also be used to meet hydrocarbon dew point pipeline specifications.
  • JT Skids are always used in conjunction with a dehydration unit to avoid freezing and hydrate formation.

Benefits of JT Skid Plants

  • Units in-stock and available
  • Skid mounted for quick and easy installation
  • Flexible leasing arrangements
  • Reliable equipment
  • Experienced engineering to assist in sizing and selection of unit
  • Professional service technicians with years of experience to maximize run-time

How JT Skid Plants Work

Following gas separation and dehydration, high-pressure gas enters the JT unit through the heat exchanger for cooling.  The natural gas stream then passes through a JT valve causing a pressure drop and undergoes a process called “adiabatic expansion.”  This means that the gas is expanding in a system where energy can neither enter nor exit.  With the energy stable, the temperature of the gas must drop to offset the pressure drop, this is called the Joule-Thompson (JT) effect.

Next, the cooled gas is routed to the separator to remove the NGL. The outlet gas from the separator is routed through the gas/gas exchanger for inlet cooling and to warm up the sales gas. The NGL from the separator is routed to a separate, optional pressurized NGL storage tank or to a NGL pipeline.
