An integrated gas turbine/air separation system is operated at or below full system load by feeding the air separation unit with air from a dedicated air feed compressor and optionally with extracted air from the gas turbine air compressor. When the gas turbine air compressor discharge drops below a selected pressure at part load conditions, the flow of extracted air to the air separation unit is discontinued and the air separation unit operates at constant pressure supplied only by the air feed compressor. This mode of operation is particularly useful i...
[ We claim:] [1.] A method of operating an integrated gas turbine/air separation system at part load which comprises compressing a first stream of air in a gas turbine air compressor, combusting at least a portion of the resulting compressed air with a fuel in a gas turbine combustor to form hot combustion products, expanding the hot combustion products in a gas turbine expander which drives the compressor, separating air into nitrogen-rich and oxygen-rich products in a cryogenic air separation unit wherein feed air to the air separation unit is provided...
