A system includes a gas turbine. The gas turbine includes a first compressor configured to provide a first portion of a discharge air to a combustor. The gas turbine also includes the combustor configured to combust a mixture of the first portion of the discharge air and fuel to generate an exhaust gas and to provide the exhaust gas to a turbine. The gas turbine also includes an exhaust outlet coupled to the turbine and configured to enable the exhaust gas to exit the gas turbine. The system also includes a nitrogen purification system coupled to the gas turbine. The nitrogen purification system includes a membrane nitrogen generator configured to receive a second portion of the discharge air from the compressor or a portion of the exhaust gas from the exhaust outlet, wherein the membrane nitrogen generator is configured to generate nitrogen from the second portion of the discharge air or the portion of the exhaust gas.

A combined cycle power plant includes a gas turbomachine, a steam turbomachine operatively connected to the gas turbomachine, a heat recovery steam generator (HRSG) operatively connected to the gas turbomachine and the steam turbomachine, and a cooling system fluidly connected to the gas turbomachine. The cooling system is configured and disposed to pass a coolant through the gas turbomachine to absorb heat. A condensate system is fluidly connected to the steam turbine and the HRSG. The condensate system is configured and disposed to deliver a steam condensate from the steam turbine to the HRSG. A heat exchange member is fluidly connected to the cooling system and the condensate system. The heat exchange member is configured and disposed to transfer heat entrained in the coolant to the steam condensate.
