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.

Heat of Dissolution Measurements for CO(2) in Mixed Alkanolamine Solvents.

Abstract	The main objective of this project is to measure heat of dissolution of CO(sub 2) in carefully selected mixed alkanolamine solvent systems, and provide such directly measured data that might be used for efficient design of CO(sub 2) capture processes, or for better understanding of thermodynamics of CO(sub 2)-alkanolamine systems. Carbon dioxide is one of the major greenhouse gases, and the need for stabilization of its composition in earth's atmosphere is vital for the future of mankind. Although technologies are available for capture and storage of CO(sub 2), these technologies are far too expensive for economical commercialization. Reduction of cost would require research for refinement of the technology. For more economical CO(sub 2) capture and regeneration, there is a need for development of more efficient solvent systems. In this project we will extend the thermodynamic database by measuring heat of solution data of CO(sub 2) in mixed solvents made of MEA (monoethanolamine), MDEA (methyldiethanolamine), piperazine, and water. Mixed solvents of different compositions will be selected and in each case data will be measured at temperatures 40 and 80 C and various partial pressures of CO(sub 2). At the end of the project, observations, conclusions, and recommendations will be derived for the choice of mixed solvents for efficient CO(sub 2) capture with potential for commercialization.
