We’re an industry leader in two large capital project areas: Ethane recovery for ethylene manufacture and lean natural gas conditioning before liquefaction. We leverage both and associate them with CRYOMAX® to best serve our clients.

Philip Hagyard, VP LNG Product Line, Technip Energies

Technip Energies is a leader in designing and delivering LNG and other large capacity gas plants equipped with NGL recovery. Our gas fractionation process designs provide solutions for a wide range of gas processing needs. Our experience dates back to affiliate Fish Engineering’s work with turbo-expander plants in the 1960s. We later pioneered their use in propane recovery. Our CRYOMAX® family of gas fractionation processes enable high-yield recovery of C2+ and C3+ hydrocarbons from natural gas and refinery offgases with low energy consumption.

From simple dew pointing units upstream of pipelines to market-leading design and delivery of large capacity plants, we’re proud of our rich history in the NGL recovery industry.

These large capacity plants are commonly associated with steam crackers for ethylene production. Our high-performance LNG trains include deep NGL recovery through cryogenic fractionation to facilitate startup and stabilize LNG product quality while widening the product slate to provide petrochemical feedstock such as ethane and LPG. The flexibility that a CRYOMAX® unit brings to an LNG train is one of the hallmarks of our company.

Extensive experience and expertise in NGL recovery

  • Energy-efficient and cost-optimized cryogenic processes
  • Solutions for a wide range of gas processing requirements
  • Processes for gas fractionation that allow the recovery of C2+ and C3+ hydrocarbons from natural gas and refinery offgasses or liquefaction feed gas preparation.

CRYOMAX® family of gas fractionation processes

CRYOMAX® processes achieve a high NGL recovery rate and reduce the investment cost per ton of produced ethane or propane as compared to conventional expander plants while minimizing operating costs. They also enable lowered energy consumption and when required, features such as flexible ethane production to match downstream user requirements with consistently high propane recovery.

We also offer tailor-made schemes for optimized aromatics and C5+ removal in LNG plants.

Additionally, CRYOMAX® provides the possibility to perfectly cut feed gas upfront of a liquefaction unit into a light stream suitable for liquefaction as LNG (C4-) and recoverable condensates (C5+).

CRYOMAX® is now available under a stand-alone license to achieve clients’ demand for independent selection of the best NGL recovery technology at an early stage of project development. Equipped with an expert commercial team for the CRYOMAX® suite of technologies, we can help our clients use this valuable technology from a project’s launch.
