Joule-Thomson (JT) Plants

  • Control hydrocarbon dew point to comply with pipeline specifications
  • Extract valuable natural gas liquids (NGLs), significantly increasing revenue
  • Simple and less expensive alternative to standard refrigeration plant
  • No electricity required and contains no moving parts
  • Includes methanol injection pump, multiple injection ports and spray distributors
  • Standard and custom packaged JT plants available
  • Skid-mounted for simple installation at any remote location

Our Joule-Thomson (JT) plants prepare gas for pipeline transmission by removing hydrocarbon liquids that provide an additional revenue stream. Employing the Joule-Thomson effect, named for the men who discovered it in 1854, the JT plant is a self-refrigeration system that uses a drop in gas pressure, which allows the gas to expand, to create a cooling effect. The unit condenses heavy hydrocarbons out of the gas to meet required gas pipeline specifications. Excess liquids that may condense and cause problems in transmission are recovered and stored for fractionation into sellable hydrocarbon components. The heavier the hydrocarbons contained in the gas, the higher the GPM value.

To ensure faster delivery, Joule strives to keep our standard packaged JT plants in stock. Our standard JT plants are skid-mounted and designed to be loaded and off-loaded from a flatbed truck. Each model is designed with three flanged customer connections (gas inlet, gas outlet, liquid outlet), pre-piped to the edge of the skid. All units include optional methanol injection port with distributor for low temp refrigeration.

Joule determines which of our four standard sizes will best fit each client’s needs, based on the client’s flow rate, pressure, temperature and composition.

Standard Plant Offerings

Joule offers the following standard JT Plants for quick delivery:

  • 50 MMSCFD
  • 100 MMSCFD
  • 200 MMSCFD

Joule utilizes an 80/20 standardization design philosophy. Based on years of experience, many projects, and hundreds of simulations, we have developed on-skid modules for each design case that are now 80% of the standard. The remaining 20% allows us to customize up to 20% of the design based on each client’s economic drivers, such as instrumentation, column size and exchanger sizing. The 80/20 approach provides “standard” price and delivery, yet custom fit for each application.
