Environmentally benign in terms of emissions, CAP is a chemical absorption process using an ammoniumbased aqueous solvent that, when contacted to the flue gas, binds to the CO 2 in a reversible reaction. CAP advantages: Tolerant to oxygen and flue gas impurities Stable, low cost, and globally available, with no degradation or emission of trace contaminants High CO 2 purity (>99.9 percent) making the product suitable for all commercial applications Low in moisture to allow for transport, distribution and storage without corrosion Efficient integration with many industrial applications since it can be used with a wide range of energy sources Our technologies can be scaled down to fit industrial needs. Flue gas from sources such as power plants, steel mills, cement factories, refineries and chemical plants can be treated with GE s CO 2 capture technology before either being sent to permanent underground storage or re-used in the production of CO 2 -enhanced oil recovery, urea, methanol, carbonates or other industrial processes. s Typical Expected Values Flue Gas Inlet Conditions Temperature ( C) < 45 Pressure (bara) 1 Flow Rate (t/h) > 4 C0 2 Vol (% dry basis) 4 40 H 2 O Vol (%) 5 30 N 2 Vol (% dry basis) O 2 Vol (% dry basis) 3 10 C0 2 Capture Rate (%) 90 CO 2 Product Specification and Conditions Temperature ( C) As Required Pressure (bara) As Required Flow Rate (t/h) Up to 25 C0 2 (mol-%) As Required and Up to Food Grade Possible N 2 (mol-ppm) < 0.25 NH 3 (mol-ppm) < 10 H 2 O (mol-ppm) < 10 NOTE: Our CO 2 capture processes could be applied to CO 2 utilization. Selection will depend on CO 2 source, industry application and downstream use
