O&M Cost

← Previous | Next →

This is a standard O&M cost result screen. The solid sorbents TSA system has the following variable cost components:

•Solid Sorbent: This is the annual cost of the solid sorbent used in the system. It is a function of the concentration of CO2 in the flue gas and the flue gas flow rate.

•Auxiliary Gas: If the user has added an auxiliary natural gas boiler, the cost of the natural gas used to fuel the boiler is added here.

•Caustic (NaOH): This is the cost of NaOH caustic used by the SO2 polisher.

•Reclaimer Waste Disposal: This is the reclaimer waste disposal cost per year.

•Electricity: The cost of electricity consumed by the solid sorbents TSA system.

•Auxiliary Power Credit: An auxiliary natural gas boiler can be added by the user to provide steam and power for the Solid Sorbents TSA System. If it is added by the user then the additional power it provides is subtracted from the overall operating and maintenance cost.

•Water: This is the annual cost for water to the solid sorbents TSA system; it is mainly required for cooling and also as process makeup.

•CO2 Transport: The CO2 captured at the power plant site has to be carried to the appropriate stor- age/disposal site. Transport of CO2 to a storage site is assumed to be via pipeline. This is the annual cost of maintaining those pipelines.

•CO2 Storage: Once the CO2 is captured, it needs to be securely stored (sequestered). This cost is based on the option chosen on theT&S Config parameter screen .

•Auxiliary CCS Cooling System: (Only shown when an Air Cooled Condenser is configured.) This is the cost of the auxiliary cooling system needed when an Air Cooled Condenser is used as the plant cooling system.
