Claim 0:
1. A process comprising:
cracking a hydrocarbon in a hydrocarbon cracking system to produce a first cracking product stream;
separating the first cracking product stream into a second cracking product stream and a hydrogen-rich methane stream;
introducing the hydrogen-rich methane stream or a methane product stream to a methane pyrolysis unit;
converting, in the methane pyrolysis unit, methane received from the hydrogen-rich methane stream or from the methane product stream to hydrogen and solid carbon;
flowing hydrogen from the methane pyrolysis unit in a first hydrogen product stream; and
introducing at least a portion of the first hydrogen product stream into a furnace of the hydrocarbon cracking system;
wherein the hydrocarbon is cracked in the hydrocarbon cracking system by combusting the at least a portion of the first hydrogen product stream in the furnace of the hydrocarbon cracking system.
