Post-combustion capture: KEY ISSUES• Solvent life○○Requires very low SOx (< 10 ppm) and NO2 (< 20 ppm)Solvent could be very expensive – target: lower solvent losses• Corrosion○○Stainless steel v carbon steelInhibitors can contain V, Sn, Sb (antimony)• Energy consumption○Regeneration of solvent• Environmental impacts○Some degradation products known and regulated; others are not.http://www.ieagreen.org.uk 22
Future Direction of Research• Cost and Process Optimisation of the current MEA based Technologies○○Design of the Absorption columnReduction of Energy consumption of the regenerative column• Improvement of Current solvents○○Improving kineticsImproving additives to reduce degradation• Development of new solvents○For Examples: Chilled Ammonia process, Cansolv solvent, KS2, etc...• Environmental Impact Assessment○○Impact assessment due solvent degradationFugitive emissions (especially NH3 as one of the by-product of degradation)http://www.ieagreen.org.uk 23
