Claim 10:
11. Ethylene plant according to claim 1, having an ethylene plant steam generation circuit and a power plant circuit, the ethylene plant steam generation circuit comprising:
said cracking furnace, wherein the cracking furnace is configured to generate high pressure steam from boiler feed water;
a steam turbine configured to be driven by said high pressure steam;
a process compressor configured to be driven by the steam turbine;
a condenser configured to condense at least part of the high pressure steam;
a pump configured to pump the condensed steam to the cracking furnace as boiler feed water;, the power plant circuit comprising the waste heat recovery boiler configured to recover heat as high pressure steam,, wherein the system further comprises a first connection between the ethylene plant steam generation circuit and the power plant circuit configured to lead at least part of the high pressure steam from the waste heat recovery boiler to the at least one steam turbine of the ethylene plant steam generation circuit to drive said at least one steam turbine.
