Process for producing by-product oxygen from turbine power generation

摘要

A method is set forth for the generation of net power and the recovery of by-product oxygen-enriched gas at low power requirements. Air is compressed to elevated temperature and pressure, at least a portion of the air is combusted and a portion of the oxygen is removed from the air or combustion effluent through a membrane or adsorbent before the oxygen lean combustion effluent is expanded through a turbine to recover power for the process and net power.
