Capital Cost

← Previous | Next →

This is a standard capital cost result screen.

Each process area direct capital cost is a reduced-form model based on regression analysis of data collected from several reports and analyses of SO2 control technology units. They are described in general below. The primary factors in the model that affect the capital costs of the scrubbers are the flue gas flow rate through the scrubber, the composition of the flue gas, the Reagent Stoichiometry , and the reagent flow rate.

The Wet FGD contains the following process areas:

•Reagent Feed System: This area includes all equipment for storage, handling and preparation of raw materials, reagents, and additives used.

•SO2 Removal System: This area deals with the cost of equipment for SO2 scrubbing, such as absorption tower, recirculation pumps, and other equipment.

•Flue Gas System: This area treats the cost of the duct work and fans required for flue gas distribution to SO2 system, plus gas reheat equipment.

•Solids Handling System: This area includes the cost of the equipment for fixation, treatment, and transportation of all sludge/dry solids materials produced by scrubbing.

•General Support Area: The cost associated with the equipment required to support FGD system operation such as makeup water and instrument air are treated here.

•Miscellaneous Equipment: Any miscellaneous equipment is treated in this process area.
