Claim 21:
22. Process for producing ethylene from a hydrocarbon feed, comprising:
cracking the hydrocarbon in a cracking furnace of an ethylene plant to produce a cracked hydrocarbon-containing gas, comprising ethylene, hydrogen and methane;
separating at least part of the cracked hydrocarbon-containing gas at least into an ethylene-enriched product, a hydrogen-enriched fuel and a methane-enriched fuel;
feeding at least part of the hydrogen-enriched fuel from a separation section to a burner of the cracking furnace and/or feeding at least part of the hydrogen-enriched fuel from the separation section to a burner of a waste heat recovery boiler of a combined cycle gas turbine power plant (CCGT);
feeding at least part of the methane-enriched fuel, obtained directly from the separation section as a liquid or after liquefying a gaseous methane-enriched fuel stream from the separation section, to a methane storage;
feeding at least part of the methane-enriched fuel from the storage to the combustor of the CCGT wherein said methane-enriched fuel from the storage is vaporized before it is fed into the combustor; and
subjecting the vaporized methane-enriched fuel fed to a combustor of the CCGT, to combustion in the CCGT, thereby generating electric power and/or thereby generating high pressure steam for driving a steam turbine forming part of a steam generation circuit of the ethylene plant,, wherein at least a part of the power is electric power produced from a renewable source.
