The Fuel Gas produced by the Steam Cracker is Hydrogen-rich (84 vol% #hydrogen , 15 vol% #Methane, <1 vol% other) separated from the Components with two Carbon Atoms is sent to the Furnaces and Steam boilers to power the Steam-Cracker. As it is a low Carbon Fuel the level of Carbon Emissions are comparatively reduced. CO2 Emissions are now captured in the Mass Balance Model.
