Considerations for treating impurities in oxy-combustion flue gas prior to sequestration

Various design, engineering, and economic analyses are being investigated to better understand the cost and performance of retrofitting oxy-combustion technologies for existing power plants. Currently, we are in the process of evaluating all downstream operations in which flue gas impurities may impact the design and performance of an oxy-combustion capture system. It is our plan to identify two geological storage reservoirs that are different in their characteristics and require different degrees of gas purifications to illustrate the economic impact on reservoir selection.
