Abstract
Low carbon dioxide-emitting processes and systems for steam cracking hydrocarbons to produce products such as ethylene are described. The processes and systems involve cracking the feed in a furnace that is configured to burn a hydrogen-rich fuel, which produces less carbon dioxide than methane, which is typically used as fuel for such furnaces. The hydrogen-rich stream can be isolated and recycled from the cracker tail gas.
