JT Skids

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.

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 assembly
  • JT Units 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 SKIDS

  • 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

FEATURES

  • Exchanger
  • JT Valve
  • Separator
  • Methanol injection
  • Control system

HOW IT WORKS

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.
