Table shows the flue gas flows at different operating conditions. "Duct Burning On" represents the design case of the Mustang FEED; "Duct Burning Off" represents the design case of the Panda FEED. The minimum operating points are 58% and 60% of the design flows, respectively, representing flue gas flow near the minimum load of each power plant. The CO 2 content of the flue gas and the capture rates at the minimum operating point are assumed to be equal to the design cases. Note that the Panda design allows the flue gas and CO 2 flow rates to remain nearly constant throughout the operating range of the NGCC plant, while the Mustang design requires greater turndown. Both process designs were developed to a similar level of detail. The engineering, procurement, and construction firms (EPCs) for each project used similar "bottom-up" methods to estimate capital expenses. Budgetary quotes were collected for major process equipment. Bulk materials, labor costs, and indirect costs were estimated by each EPC using internal data and estimation methods. Labor costs for the Mustang FEED are based on labor rates for Houston, TX plus per diem to adjust for the Denver City, TX location. Labor costs for the Panda FEED are based on previous EPC experience at the Sherman, TX site adjusted to the year in which the estimate was conducted. Estimates were developed in 2021. Due to the similar geographic location and timeframe of both estimates, no adjustments are made in this comparison for differences in costs due to location or cost escalation.
