O&M Cost

← Previous | Next →

The O&M Cost parameter screen combines the variable O&M unit costs from all the model components and places them in one spot. These values will also appear in the technology input screens where they are actually used. Values changed on this screen will reflect exactly the same change everywhere else they appear. O&M costs are typically expressed on an average annual basis and are provided in either constant or current dollars for a specified year, as shown in the Status Bar.

The following costs may be specified:

•Activated Carbon Cost: This is the cost of activated carbon.

•Ammonia Cost: This is the cost of ammonia.

•Beavon-Stretford Catalyst Cost: This is the cost of the catalyst used for the Beavon-Stretford sulfur recovery system.

•Caustic (NaOH) Cost: This is the cost of caustic (NaOH) gas.

•Claus Plant Catalyst Cost: This is the cost of the catalyst used by the Claus sulfur recovery system.

•Glycol Cost: This is the cost of glycol used by the Selexol CO2 capture system.

•Shift Reactor Catalyst (Hi-T): This is the cost of the high temperature catalyst used for first Water Gas Shift Reactor (WGSR) stage.

•Shift Reactor Catalyst (Low-T): This is the cost of the low temperature catalyst used for the second WGSR stage.

•Urea Cost: This is the cost of urea.

•Ionic Liquid Cost: This is the cost of the solvent used by the Ionic Liquid CO2 capture system.

•Water Cost: This is the cost of water in dollars per thousand gallons.

•Taxes & Insurance: This is the cost of taxes and insurance. This parameter is included as fixed O&M costs and is estimated empirically as a percent of the TPC.

•Operating Labor Rate: This is the hourly cost of labor. This same value is used throughout the individual technologies. (See O&M Cost Inputs .)

•Sulfur Byproduct Credit: This is the credit for sulfur sold on the market as collected by the Claus and Beavon-Stretford plants.

•Real Escalation Rate (for all above) (%/yr): This is the annual rate of increase of an expenditure due to factors such as resource depletion, increased demand, and improvements in design, manufacturing or construction techniques (negative rate). The real escalation rate does not include inflation.
