The adjusted direct field cost (Cost F EED ) developed in Section 3 was used for calculating Mustang scaled costs per category (Cost scaled ). Table lists the costs by area and scaling parameter applied to each area. For this scaling, the process is divided into nine major process areas and an "Other" category representing general utilities and other outside battery limits (OSBL) costs. The Absorber, Heat Exchangers, Pumping & Conditioning, and Water Wash categories combined correspond to the CO 2 Absorption category as shown in Table . CO 2 Stripping and Solvent Reclaiming correspond to the Solvent Regeneration category. In Section 4, the "Other" cost is distributed proportionally to the five categories. Areas expected to scale with flue gas flow are scaled by (81%) 0.6 = 88% and areas scaled by CO 2 capture flow are scaled by (69%) 0.6 = 80%. This scaling assumes a 0.6 scaling factor as commonly used for scaling process equipment .
