The disclosed embodiments relate to a system and method that allows air to be extracted from a plurality of gas turbine engines and fed to a downstream process, even in situations in which one or more of the gas turbine engines are operating in a part load condition. For example, in an embodiment, a method includes monitoring signals representative of a header pressure of a header, or a pressure of extraction air flow from one or more gas turbine engines to the header, or both, and maintaining substantially continuous flows of extraction air from the gas turbine engines to the header. The substantially continuous flows are maintained when the gas turbine engines are under symmetric and asymmetric load conditions.

The present embodiments are directed towards the cooling of a solvent of a gas treatment system using a fluid flow from an air separation unit. In one embodiment, a system is provided that includes an air separation unit. The air separation unit has an air inlet configured to receive an air flow, an oxygen outlet configured to output an oxygen flow, a nitrogen outlet configured to output a nitrogen flow and a cooling system configured to cool the air flow to enable separation of the air flow into the oxygen flow and the nitrogen flow, wherein the cooling system is configured to cool a first solvent of a first gas treatment system.
