National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

CO(2) Capture by Absorption with Potassium Carbonate.

DE2004822319

Publication Date	2003
Personal Author	Rochelle, G. T.; Chen, E.; Cullinane, J. T.; Hilliard, M.; Oyenekan, B.; Jones, T.
Page Count	56
Abstract	The objective of this work is to improve the process for CO2 capture by alkanolamine absorption/stripping by developing an alternative solvent, aqueous K2CO3 promoted by piperazine. A rigorous thermodynamic model has been further developed with a stand-alone FORTRAN code to represent the CO2 vapor pressure and speciation of the new solvent. Gas chromatography has been used to measure the oxidative degradation of piperazine. The heat exchangers for the pilot plant have been received. The modifications are on schedule for start-up in November 2003.
