preferentially absorb a gaseous species from the gas mixture. Physical absorption is being used in smaller- scale industrial applications. Although physical solvent regeneration is less energy-intensive than Table 1. Post-Combustion Capture Advantages and Challenges CO2 Capture Technology Description Advantages Challenges Solvent reacts reversibly with CO2, often forming a salt. Solvent is regenerated by temperature swing, which reverses the absorption reaction (normally exothermic). Solvent is often alkaline. • Chemical solvents provide fast kinetics to allow capture from streams with low CO2 partial pressure • Wet-scrubbing allows good heat integration and ease of heat management (useful for exothermic absorption reactions) • Significant amount of steam required to reverse chemical reaction de-rates power plant • Energy required to heat, cool, and pump non-reactive carrier liquid (usually water) is often significant • Vacuum stripping can reduce regeneration steam requirements but is expensive Liquid Solvent Solid Sorbent When sorbent pellets are contacted with flue gas, CO2 is absorbed onto chemically reactive sites on the pellet by a reversible reaction. Pellets are regenerated by temperature swing, which reverses the absorption reaction. Uses permeable or semi- permeable materials that allow for the selective transport and separation of CO2 from flue gas. • Chemical sites provide large capacities and fast kinetics, enabling capture from streams with low CO2 partial pressure • Higher capacities on a per mass or volume basis than similar wet-scrubbing chemicals • Lower heating requirements than wet-scrubbing in many cases (CO2 and heat capacity dependant) • No steam load • No chemicals • Heat required to reverse chemical reaction (although generally less than in wet- scrubbing cases) • Heat management in solid systems is difficult, which can limit capacity and/or create operational issues when absorption reaction is exothermic • Pressure drop can be large in flue gas applications • Sorbent attrition • Membranestendtobemore suitable for high-pressure processes such as IGCC • Tradeoffbetweenrecovery rate and product purity (difficult to meet both high recovery rate and high purity) • Requireshighselectivity (due to CO2 concentration and low pressure ratio) • Goodpre-treatment • Badeconomyofscale • Multiplestagesandrecycle streams may be required Membrane chemical systems, this technology is considered more practical for processing the high-pressure syngas generated at co al g asification p lants s ince C O2 solubility in p hysical s olvents in creases w ith p artial pressure. Practical challenges in solvent-based CO2 capture include large flue gas volume, relatively low CO2 concentration, flue gas contaminants, and high parasitic power demand for solvent recovery. Technology ne eds i nclude l ow-cost, no n-corrosive s olvents that ha ve h igh C O2 loading c apacity, improved reaction kinetics, low regeneration energy, and resistance to degradation.
