2-Step w/ Air Sweep

The following diagram is shown for the 2-Step w/ Air Sweep and NETL 2-Step w/ Sweep configurations:

PC: GET RESULTS: CO2 Capture, Transport & Storage: 1. Membrane System: Membrane System Diagram (2-Step w/ Air Sweep)

The following results are shown:

•Area 1:

•Temperature In: This is the temperature of flue gas entering the membrane system.

•Flue Gas In: This is the flow rate of flue gas entering the membrane system.

•Area 2:

•Water: (Only shown for 2-Step w/ Air Sweep) This is the amount of water condensed out from the permeate stream.

•Total Membrane Area: This is the total membrane surface area.

•Area 3:

•Air + CO2 to Boiler: This is the flow rate of combustion air + permeated CO2 recycled to the boiler.

•Area 4:

•Air: This is the flow rate of combustion air used as a sweep gas.

•Area 5:

•Temperature Out: This is the temperature of flue gas exiting the membrane system.

•Flue Gas Out: This is the flow rate of flue gas exiting the membrane system.

•Area 6:

•CO2 Product: This is the amount of CO2 captured.

•Area 7:

•Water: This is the amount of water removed by the CPU.

•Vented Gas: This is the amount of CO2 vented at the CPU.
