  • Oxygen recovery from turbine exhaust using solid electrolyte membrane
    Patent number: 5174866
    Abstract: A process is provided for extracting high purity oxygen from a gas generator turbine exhaust stream by passing the turbine exhaust over the feed side of solid electrolyte membrane selective to the permeation of oxygen over other components of the exhaust stream to separate the oxygen from the exhaust stream, and removing the oxygen product stream from the permeate side of the membrane. The reject exhaust stream is then passed through a power generating turbine to recover net power.
