A cryogenic processing plant is a facility where natural gas flowing from wells is cooled to sub-zero temperatures in order to condense liquids or NGLs (natural gas liquids). These can include butane, ethane and propane. NGLs are shipped to market and often used in refineries and petrochemical plants for fuel or feedstock. The methane gas that remains after removing liquids is transported via pipeline to where it is needed.

Typically a plant separates NGLs from natural gas by chilling the gas stream down to around -120 degrees Fahrenheit. This allows a blended liquid hydrocarbon feedstock to be collected which then is fed into a fractionation plant that finishes processing the liquid hydrocarbon or Y Grade into high purity propane, butane and natural gasoline.

  • 90%+ ethane recovery
  • 99.9% propane and heavier recovery
  • Capable with efficient Ethane rejection mode
  • Designed with maximum turndown operation
  • Fast-track design available upon request
  • Skid-mounted for simple installation and mobility
EnerProcess custom cryogenic plants are designed to recover ethane from the natural gas stream with virtually no loss of propane and heavier components. Cryogenic plants do so by chilling the feed gas via turbo expansion to significantly lower temperatures possible with standard refrigeration plants. With a modular design that allows for faster deliverability and makes hookup and field construction easier, our plants are built to meet our clients' desired conditions. Each cryogenic plant is designed to operate in ethane rejection mode while retaining maximum propane recoveries. EnerProcess specializes in smaller to midsize cryogenic applications, yet all designs are fully scalable in size.
