Capital Cost

← Previous | Next →

This is a standard capital cost result screen. The following process area costs are shown:

•Boiler Modifications: In case of a pre-existing PC plant being retrofitted for CO2 capture, the boiler must be modified to suit the new oxyfuel combustion system. The cost for these modifications is estimated as a percentage of the cost of the boiler.

•Flue Gas Recycle Fan: The cost of the fan required for recycling part of the flue gas is scaled on the basis of the flow rate of the flue gas being recycled.

•Flue Gas Recycle Ducts: Additional ducting is necessary to recycle part of the flue gas in the oxyfuel combustion system. The cost of this ducting is assumed to be a function of the flow rate of recycled flue gas.

•Direct Contact Cooler: The cost of the flue gas cooler is scaled on the basis of the flow rate of the flue gas.

•CO2 Cryogenic Purification Unit: This area shows the direct capital cost of the CPU. The CPU purifies, dries, and compresses the CO2 product stream for transport over long distances.
