Breakthrough CO2 Capture Technology

Providing state of the artgas absorption solutionsBreakthrough CO2Capture TechnologyThe CANSOLV? CO2 Capture (patent pending)process is a groundbreaking low cost solution forselectively absorbing CO2 from flue gas or chemicaloff-gas environments. This process uses aformulated high performance amine absorbent toachieve best in class process economics andversatility.Unlike conventional amine based processes, theCANSOLV? CO2 Capture process can be used inoxidizing environments such as conventional boiler &power plant flue gases, cement or lime kiln gases oroxygen rich reaction off-gases. Likewise, theCANSOLV? CO2 Capture can be used in thepresence of limited concentrations of oxidized sulfur.With higher sulfur containing flue gases, the processcan be integrated in a cost efficient fashion with theCANSOLV? SO2 absorption process.Independent laboratories have tested product CO2from the CANSOLV? CO2 process and haveconfirmed 99.9999% purity on a dry basis. Thisgroundbreaking process now makes it possible toproduce high purity CO2 on site from flue gases at alower cost than bulk supply without the burden oftransportation and storage.Cansolv CO2 Capture Applications:• GHG abatement and sequestration• Recycle of CO2 for enhanced oil recovery• Recovery of CO2 for wastewater pH control• Pulp and paper processes:o Pulp acidificationo Precipitated calcium carbonateproductiono Lignin precipitation• Distributed CO2 supply for food and beverageindustry• Greenhouse CO2 enrichmentCansolv Technologies Inc.8475 av.

Feed gas to the CANSOLV® CO2 Capture process is firstquenched and saturated in a water spray prescrubber. Thiscan also remove residual particulates and strong acids2. The gas is then contacted with the lean amine solution in acounter-current absorption column where the CO2 isabsorbed.3. The rich amine from the absorption column is pumped to theregeneration column via a lean/rich heat exchanger forenergy recovery. The rich amine solution is regenerated bysteam stripping and the CO2 is recovered as a pure, water-saturated product. The lean amine leaves the reboiler andis pumped back to the absorption column via the lean/richheat exchanger and the lean amine cooler.4. A slipstream of the amine is purified to prevent accumulationof heat stable salts.5. The by-product can be used directly at the column pressure(5 to 30 psig) or pressurized and dried as needed.Performance characteristics• Ultra-low solvent degradation rates (less than 5% per year)independent of oxygen content• Low specific heat of regeneration (<1.5 lb per lb at 12%CO2, less at higher concentrations)• Can be used with a combustion gas, or industrial gas withany CO2 concentration.• Trusted and reliable process• Low capital and operating cost per ton CO2• Low maintenance
