The Ammonia System Diagram result screen shows the major flows into and out of the ammonia CO2 control system in PC and NGCC plants:

PC: GET RESULTS: CO2 Control: 1. Ammonia System: Ammonia System Diagram

The following values are shown:

•Area 1: Reagent:

•Lean Solv. Flow: This is the lean solvent circulation flow rate.

•Ammonia: This is the makeup solvent.

•Water: This is the water used to dilute the makeup solvent.

•Area 2: DCC:

•Makeup Water: This is the amount of makeup water required.

•Reclaimer Waste: Total solids mass flow rate of solids removed from the ammonia scrubber.

•Cooling Water: This is the total cooling water required for the ammonia system.

•Chilled Water: This is the amount of chilled water required for all of the chillers in the ammonia system.

•Bleed Water: This is the amount of bleed water.

•Refrig. Req.: This is the amount of refrigeration required for all of the chillers in the ammonia system.

•Area 3: Flue Gas Entering Ammonia System:

•Temperature In: Temperature of the flue gas entering the ammonia system.

•Flue Gas In: Volumetric flow rate of flue gas entering the ammonia system.

•Fly Ash In: Total solids mass flow rate in the flue gas entering the ammonia system. This is determined by the solids exiting from the module upstream.

•Mercury In: Total mass of mercury entering the ammonia system. The value is a sum of all the forms of mercury (elemental, oxidized, and particulate).

•Area 4: Flue Gas Exiting Ammonia System:

•Temperature Out: Temperature of the flue gas exiting the ammonia system.

•Flue Gas Out: Volumetric flow rate of the flue gas exiting the ammonia system.

•Fly Ash Out: Total solids mass flow rate in the flue gas exiting the ammonia system.

•Mercury Out: Total mass of mercury exiting the ammonia system. The value is a sum of all the forms of mercury (elemental, oxidized, and particulate).

•Area 5: Ammonia System Performance:

•CO2 Product: Actual amount of CO2 produced.

•CO2 Pressure: Compressed CO2 product pressure. The product stream is compressed for transport to a sequestration site.

•CO2 Removal: Actual removal efficiency of CO2.

•Rich Stream Solids: This is the percentage by weight of solids in the rich solution.
