Mining and Clustering Textual Requirements to Measure Functional Size of Software with COSMIC.

An air separation plant includes a product nitrogen compressor, a gas turbine and a steam turbine. The gas turbine and the steam turbine are operatively associated with the product nitrogen compressor so as to be able to drive the product nitrogen compressor. The steam turbine has an inlet communicating with a steam generator adapted to recover heat from the gas turbine. The air separation plant also includes an air compressor which is typically similarly operatively associated with a gas turbine and a steam turbine. The steam turbine has an inlet communicating with a steam generator adapted to recover heat from the gas turbine.
