(110a) Ethylene Production and Decarbonization Strategy Using Oxidative Coupling of Methane

Oxidative Coupling of Methane (OCM) upgrades low-value methane-rich feedstock into high value petrochemicals. Latest improvements in Lummus’ Gemini® OCM technology bring it closer to commercial deployment on a cost-competitive basis. It also offers an avenue for reduction in CO₂ emissions. OCM can be deployed in a stand-alone mode using natural gas and gas liquids as feedstock; integrated with a Gas Plant; integrated with a steam cracker; or utilize CO₂ as a feedstock. Different process schemes can be employed for OCM when external H₂ source, particularly from a green source such as electrolysis is available, CO₂ itself can be used as a feedstock to produce green ethylene using OCM. Some of the salient features of this technology and the different flow schemes will be discussed in this paper.
