CO2 Capture by Absorption With Potassium Carbonate

[摘要] The objective of this work is to improve the process for CO{sub 2} capture by alkanolamine absorption/stripping by developing an alternative solvent, aqueous K{sub 2}CO{sub 3} promoted by piperazine. A rigorous thermodynamic model has been further developed with a standalone FORTRAN code to represent the CO{sub 2} vapor pressure and speciation of the new solvent. The welding work has initiated and will be completed for a revised startup of the pilot plant in February 2004.
