A world leader in the design and construction of ethylene facilities

Scroll down for more

Technip Energies is a world leader in the ethylene industry with 40-50 percent of the licensing market share. We have unique experience in the design, construction and modernization of the largest ethylene plants using proprietary technologies.

We handle steam crackers from conception to commissioning with renowned references such as:

  • DOW LHC9, the world’s largest steam cracker operating in the USA;
  • Sadara, the world’s largest mixed feed cracker in KSA;
  • Reliance, the world’s only dedicated refinery offgases cracker in India;
  • and major ethane crackers such as CPChem in the USA and Etileno XXI in Mexico.

End-to-end support for the world’s ethylene industry

During the early stages of a project, we carry out conceptual studies that evaluate the technological robustness, CAPEX and environmental constraints of possible solutions leveraging our extensive FEED and EPC experience.

Accelerating the energy transition

We have worked continuously to improve the energy efficiency of ethylene plants, reducing total installation costs per ton of ethylene and reducing hydrocarbon consumption per ton by 5-10 percent. Our innovations have also resulted in a 30-percent reduction in CO2 emissions. Whether you need a new plant or are updating an existing unit, we can help you improve your energy efficiency and increase feed utilization and flexibility while lowering emissions.
