ABSTRACT:
An air separation plant operates at elevated pressures and with reflux to produce an oxygen product and a nitrogen product which is indirectly heat exchanged with the compressed main air feed therefor to produce a hot nitrogen product.
The air separation plant is interlinked with a steam generator by indirectly exchanging high-grade heat from the flue gases to the hot nitrogen product to form a very hot nitrogen product, by work-expanding the very hot nitrogen product, and by indirectly exchanging lower-grade heat from the work-expanded nitrogen product to the heated fluids of the steam generator so that compression heat is recovered as mechanical energy, the temperature distribution in the steam generator is improved to diminish irreversibility of heat exchange within the steam generator and increase total efficiency of the interlinked plants, and the nitrogen product is uncontaminated and recoverable.
