Alloys for Ethylene Production Furnaces

Stage: Development
Ethylene production is one of the most energy intensive processes in the chemical industry, due to the decoking necessary to maintain ethylene furnace tubes.

Oak Ridge National Laboratory and its industrial partners are developing and testing new intermetallic and metallic alloys that are resistant to coke build-up and carburization, along with the tube fabrication and welding methods necessary to implement the new alloys.

Applications and Industries




The new materials will reduce the frequency of decoking and help save energy, boost productivity, and increase the structural life of the tubes.
