The CO 2 absorption section represents equipment associated with absorbers as well as solvent cross-exchangers and other heat exchangers. A detailed discussion of absorber costs is presented in Section 7. The Mustang FEED absorbers include intercooling, which is absent in the Panda FEED design. Due to limited water availability, Mustang uses air cooling for both wash water and intercooler cooling duty. Air cooling bays and associated piping represent a major cost in the Mustang design. The subcategory "Heat Exchangers" (in Table ) represents only the solvent cross-exchangers and stripper steam heaters. The air cooling bays and associated piping for the absorber intercoolers are included under "Pumping & Conditioning", and the air cooling bays and piping for water wash cooling are included under "Water Wash".
