FG Recycle & Purification Diagram

 

The FG Recycle & Purification Diagram result screen shows the major flows into and out of the flue gas recycle system:

PC: GET RESULTS: CO2 Control: 2. FG Recycle & Purification: FG Recycle & Purification Diagram

The following values are shown:

•Area 1: Primary Recycle: The primary split occurs after the direct contact cooler. The following results refer to the primary flue gas recycle stream:

•Temperature: This is the temperature of the flue gas.

•Flue Gas Flow: This is the volumetric flow rate of the flue gas.

•Area 2: Secondary Recycle: The secondary split occurs before the spray dryer. The following results refer to the secondary flue gas recycle stream:

•Temperature: This is the temperature of the flue gas.

•Flue Gas Flow: This is the volumetric flow rate of the flue gas.

•Area 3: Combined Recycle Flue Gas:

•Temperature: This is the temperature of the flue gas.

•Flue Gas Flow: This is the volumetric flow rate of the flue gas.

•Fly Ash Flow: This is the flow rate of fly ash in the flue gas.

•Water Fraction: This is the fraction of water in the flue gas.

•Area 4: Direct Contact Cooler:

•4a: In:

•Temperature In: The temperature of the flue gas, to be recycled, entering the direct contact cooler.

•Flue Gas In: The volumetric flow rate of the flue gas, to be recycled, entering the direct contact cooler.

•Fly Ash In: The mass flow rate of fly ash in to the direct contact cooler.

•4b: Out:

•Condensed H2O: The mass flow rate of condensed water leaving the direct contact cooler.

•Sulfur Removed: This is the amount of sulfur removed on the direct contact cooler.

•Area 5: Released to Atmosphere:

•Temperature Out: The temperature of the flue gas being released to the atmosphere.

•Flue Gas Out: The volumetric flow rate of the flue gas being released to the atmosphere.

•Fly Ash Out: The mass flow rate of the fly ash being released to the atmosphere.

•Area 6: Other:

•Condensed H2O: The mass flow rate of condensed water.

•CO2 Product Pressure: This is the target pressure of product CO2 being sent to storage.

•CO2 to Storage: The mass flow rate of CO2 being sent to storage.
