GET RESULTS: Water System: Makeup Water Diagram

The following values are shown:

•Area 1:

•Plant Makeup Water: This is the total amount of makeup water required by the plant. This is demineralized makeup water.

•Area 2:

•Cooling Makeup Water: This is the amount of makeup water for the cooling system. For the wet cooling tower, the makeup water is required to offset the evaporation, blowdown, and drift losses.

•Area 3:

•Process Makeup Water: This is the amount of makeup water required for the three major process areas. This represents the net process makeup water consumption.

•Area 4: Makeup

•Reforming: This is the amount of water consumed for steam generation. Steam is required for natural gas reforming.

•Syngas Cleanup: This includes water associated with the wash column operation and solvent makeup requirements, which depend on the MDEA solvent makeup rate during syngas cleanup.

•Flue Gas Capture: This includes water associated with the wash column operation and solvent makeup requirements, which depend on the MEA solvent makeup rate during flue gas CO2 capture.

•Area 5: Recycle for Reforming

•Syngas Cleanup: This is the amount of water recovered and recycled during the MDEA regeneration process.

•Flue Gas Capture: This is the amount of water recovered and recycled during the MEA regeneration process.
