Ethylene decarbonization projects and technologies

Technip Energies is a world leader in the ethylene industry with 40-50 percent of the licensing market share. With 65 years of experiences in the design, construction and modernization of the largest ethylene plants using proprietary technologies, our clients benefit from our unrivaled expertise.

We conduct conceptual studies for our clients that evaluate the technological robustness, CAPEX and environmental constraints of possible solutions leveraging our extensive FEED and EPC experience.

Our track record includes handling 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 off-gas cracker in India

Major ethane crackers such as CPChem in the USA and Etileno XXI in Mexico.

Powering the energy transition with ethylene decarbonization for a cleaner climate

We have worked continuously to improve the energy efficiency of ethylene plants, lowering total installation costs per ton of ethylene and reducing hydrocarbon consumption per ton by 5-10 percent.

Our innovative low-emission ethylene cracker can reduce CO₂ emissions by 30 percent. Other ways to decarbonize include adding post-combustion carbon capture to achieve up to 99 percent capture efficiencies and replacing the methane fuel from the process with alternative lower-carbon fuels such as hydrogen. We also are piloting a proprietary electric furnace and other advanced technologies.

Whether you need a new plant or an existing unit update, we can help you improve your energy efficiency and increase feed utilization and flexibility while lowering emissions.
