摘要
CO2 may be recovered from flue gas by a hybrid system utilizing both gasseparation membranes and adsorption. Purified flue gas is separated by the gasseparation membrane into permeate and non-permeate streams. The permeatestream is compressed, partially condensed at a heat exchanger, and phase-separated to produce a vent gas and high purity liquid CO2. The vent gas isrecycledto the membrane. The non-permeate is fed to a PSA unit. The CO2 blow-down fromthe PSA unit is also compressed with the permeate stream. The adsorbent in thePSA unit is regenerated with combustion air and the CO2-containing combustionairis fed to a combustor for combustion with fuel and an oxidant to produce thefluegas.
