The intent of this comparison is to understand and reconcile differences in cost that are driven by the layout and constraints of the host sites or by differences in estimation methods. This comparison discusses how the respective amine scrubbing technologies affect the cost of equivalent areas of each process. However, no attempt is made to reconcile these differences or compare the merits of the two technologies. The cost estimates in both FEEDs were developed during 2021, so no adjustment is made for cost escalation. There is no adjustment for location, as it is assumed that both sites, being located in the same region, have similar costs for labor, freight, etc.
