“…There are various technologies used to separate CO 2 from flue gas streams. These include chemical solvent methods, physical absorption methods, cryogenic methods, membrane systems, biological fixation, and the O 2 /CO 2 combustion process (Wolsky et al (1994), Nishikawa et al (1995), Kimura et al (1995)). The chemical solvent methods are generally recognized as the most effective technologies at present (Chakma (1995)).…”

This paper provides preliminary results on the novel study of ammonia scrubbing for the removal of carbon dioxide from flue gas. Experimental results indicated the potential of CO2 reduction by NH3 scrubbing is very promising. The overall CO2 removal efficiencies could be above 95% under proper operation conditions. The absorption capacity of NH3 was around 0.9 kg of CO2/kg of NH3 reagent being used. This should be higher than that by a MEA solution. The reaction products were analyzed and determined by X-ray diffraction analysis, SEM picture, and pH measurements. All the measurements indicated that an ammonium bicarbonate solution and its crystalline solids are the major products of reaction.

“…Capturing and securely storing carbon emitted from the global energy system is an important and attainable goal. Several researchers have proposed and developed possible solutions such as chemical solvents, physical absorption, cryogenic methods, membrane systems, and biological fixation. − Of these, the chemical solvent methods are currently recognized as the most effective technologies. The cost of capturing CO 2 can be reduced by finding a low-cost solvent that can minimize energy requirements, equipment size, and corrosion.…”

Development of an Analytical Method for Distinguishing Ammonium Bicarbonate from the Products of an Aqueous Ammonia CO₂ Scrubber

The link between anthropogenic emissions of carbon dioxide, increasing atmospheric CO2 levels, and concomitantly increasing global temperatures is established and accepted. The use of aqueous ammonia, to capture CO2 and produce an inexpensive nitrogen fertilizer, ammonium bicarbonate (ABC), is believed to be a feasible approach to CO2 sequestration. Due to the varying concentrations of reactants and varying reaction conditions, different ammonia-carbon compounds may be produced. ABC is the ideal product for maximizing NH3 utilization in CO2 capture; therefore, identification and quantification of ABC in the reaction products is mandatory. Various analytical techniques were used to distinguish and quantify the ABC. Fourier transform infrared spectroscopy can only be used to distinguish ammonium carbamate, and. X-ray diffraction can be used to qualitatively distinguish ABC from the other possible products of the CO2 capture reaction. Carbon-hydrogen-nitrogen elemental analysis and near-infrared (NIR) spectroscopy were used to quantify ABC, with both techniques giving +/-5% agreement for ABC concentrations for 8 of 13 samples from a bench-scale aqueous ammonia CO2 scrubbing system. An additional 3 of the 13 samples were within +/-12%. Results indicate that NIR will be an ideal tool for real-time, on-line measurements of ABC in a full-scale aqueous ammonia CO2 scrubber. The ABC in 11 samples from the bench-scale scrubber at Western Kentucky University was determined by these techniques and assessed to have very good quality as a fertilizer in accordance with GB-3559-92, the Agricultural Ammonium Bicarbonate National Standard of China.
