Variable O&M Cost

← Previous | Next →

This is an O&M Cost Input Screen which contains inputs for the amine system's variable O&M costs in PC and NGCC plants. (Fixed O&M costs are on the next screen .) The following parameters are provided:

•Sorbent Cost: (Not shown for Cansolv.) This is the unit cost of the makeup MEA.

•Inhibitor Cost: (Not shown for Cansolv.) Addition of inhibitor makes it possible to use higher concentrations of MEA solvent in the system with minimal corrosion problems. Inhibitors are special compounds that come at a cost premium. The cost of inhibitor is estimated as a percent of the cost of MEA. The model default is 20%.

•Activated Carbon Cost: (Not shown for Cansolv.) This is the unit cost of the activated carbon.

•Caustic (NaOH) Cost: (Not shown for Cansolv.) This is the unit cost of the caustic (NaOH).

•Process Chemicals: (Only shown for Cansolv.) Process chemicals include Ion Exchange Resin, NaOH, Cansolv Solvent and Triethylene Glycol.

•Water Cost: Water is mainly required for cooling and also as process makeup. Cost of water may vary depending upon the location of the power plant.

•Auxiliary Gas Cost: (Only shown when an auxiliary boiler is configured.) This is the unit cost of natural gas.

•Auxiliary CCS Cooling Cost: (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.

•Reclaimer Waste Disposal Cost: (Not shown for Cansolv.) The unit cost of waste disposal for the reclaimer waste.

•Electricity Price (internal): See the description for a standard O&M cost input screen .

•CO2 Transport Cost (Levelized): Transportation of CO2 product is assumed to take place via pipelines. This is the unit cost of CO2 transport. The cost is calculated from the pipeline sub-process model.

•CO2 Storage Cost: This is the unit cost of CO2 disposal. Depending upon the method of CO2 disposal or storage, either there may be some revenue generated (Enhanced Oil Recovery) which may be treated as a "negative cost", or additional cost (all other disposal methods).
