Claim 0:
1. Ethylene plant, comprising:
a cracking furnace for converting a hydrocarbon feedstock into a cracked gas stream;
a separation section configured to provide at least an ethylene-enriched product stream, a hydrogen-enriched fuel stream and a methane-enriched fuel stream from the cracked gas stream;
a passage way for feeding at least part of the hydrogen-enriched fuel from the separation section to a burner of the cracking furnace and/or a passage way for 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);
a methane storage configured for storing the methane-enriched fuel and a passage way for feeding at least part of the methane-enriched fuel from the separation section to the storage;
the CCGT, comprising a gas turbine—the gas turbine comprising a combustor—and a passage way for feeding at least part of the methane-enriched fuel from the storage to the combustor of the gas turbine of the CCGT, which CCGT is configured to generate electric power and/or to generate high pressure steam to drive a steam turbine forming part of a steam generation circuit of the ethylene plant; and
an electric power connection configured to provide part of the power for operating the plant, which is a connection to an electric power system to produce electric power from a renewable source.
