  • System and method of recovering carbon dioxide from an exhaust gas stream
    Patent number: 10765994
    Abstract: A carbon dioxide capture system includes a first heat exchanger that exchanges heat between an exhaust stream and a lean carbon dioxide effluent stream. The carbon dioxide capture system also includes a second heat exchanger in flow communication with the first heat exchanger. The second heat exchanger is configured to cool the exhaust stream such that a condensate is formed, and the second heat exchanger is configured to channel a condensate stream for injection into the lean carbon dioxide effluent stream. A first turboexpander including a first compressor is driven by a first turbine. The first compressor is coupled in flow communication with the first heat exchanger. The first turbine is coupled in flow communication with the first heat exchanger and configured to expand the lean carbon dioxide effluent stream. The carbon dioxide capture system further includes a carbon dioxide membrane unit coupled in flow communication with the first compressor.

  • SYSTEM AND METHOD OF REDUCING OXYGEN CONCENTRATION IN AN EXHAUST GAS STREAM
    Publication number: 20170348638
    Abstract: An oxygen scavenging system that includes a first catalytic converter unit configured to receive an exhaust stream from a power production unit. The exhaust stream includes oxygen. The system also includes a hydrocarbon injection unit configured to channel a hydrocarbon stream for injection into the exhaust stream upstream from the first catalytic converter unit such that hydrocarbons from the hydrocarbon stream react with the oxygen from the exhaust stream within the first catalytic converter unit.
