Retrofitting this plant for a 90% capture of CO 2 using an aminebasedscrubbing process would cost an incremental $599 million with a total cost of $3,865per kW.Exhibit B-3: Capture Ready and Post CCS Retrofit Capital Cost Comparison forPC Reference Plant and Amine Scrubbing OptionsCapital Cost w/ CR costs a Capital Cost w/ CCS retrofit bCapture Ready Option $000 $/kW $000 $/kWNot CCS Ready 866 1,575 1,465 3,8651: Throttle Valve Case 871 1,583 1,452 3,6822: Clutch Case 891 1,621 1,478 3,6513: Oversized Boiler Case 1,110 2,019 1,568 2,871a w/ CR – with Capture Ready pre-investmentsb w/ CCS – with CO2 capture retrofitCapture Ready Option 1 represents a minimal approach to Capture Ready, and alsorepresents a minimum savings in absolute terms of approximately $13 million or $182/kW.Option 3 has the highest initial capital cost at $1,110 million or $2,019/kW of all theoptions, because Option 3 represents a different Capture Ready approach compared withOption 1 or Option 2 (as explained above). Due to the significant upfront costs, Option 3also represents the highest-cost option in absolute terms after CCS retrofitting, at $1,56823 February 2010 80
Appendix B: Technology Design Options for a Capture Ready Plantmillion. However due to the regaining of capacity from the oversize furnace, Option 3represent the lowest cost on an output basis, at $2,871/kW.Note that the economic benefits discussed here are meant only to provide an approximategain for being Capture Ready, and the cost numbers provided above are valid to within ±30%.B.1.4 Potential for New TechnologiesNew CO 2 capture technologies under development can affect the design of a Capture Readyplant, and as such it is important to assess the potential of these new technologies and theimpact they may have on capture ready designs.As of April 2009, EPRI had determined that there are more than 50 post-combustion CO 2capture concepts and 6 physical/chemical process types under development, which can becategorized as depicted in Exhibit B-4. 130Exhibit B-4: Post-Combustion CO 2 Capture Technology GroupsSource: EPRI. (2009). 130Of these technologies, chilled ammonia-based CO 2 capture is considered a key technologythat could compete with amine-based capture. Although still under development, the chilledammonia-based CO 2 capture process is very similar to that of the amine capture process,but has a strongly reduced efficiency penalty. The greater efficiency of the chilled ammoniacapture process can be attributed to its reduced heat of reaction energy needs (60% lowerthan MEA), its ability to regenerate without stripping steam, and its greater CO 2 absorptivecapacity. 130 Other advantages include:• Lower energy requirement for solvent regeneration (steam consumption is low);• Reduced sensitivity of the solvent to acid gases such as SO x and NO x ;• Resistance to oxidative and thermal degradation;• Ability to clean the flue gases of NO x , SO x and other pollutants;130 Electric Power Research Institute (EPRI).
