Gaseous Carbon Dioxide

Abstract This paper summarizes the mass transfer modeling that can simulate the process of gaseous carbon dioxide dissolution into water in an orifice mixing system. In order to establish the operating characteristics of the orifice mixing system, ordinary tap water and pure carbon dioxide were used as the liquid-gas system. Using the model, computations were performed for an orifice mixing system to better understand the mass transfer process of gaseous carbon dioxide into water through both the elbow tube and the junction Venturi-tube. All computed results show different performance of the carbon dioxide dissolution rates for the given inlet water and carbon dioxide conditions of the four different designs of the junction type Venturi-tubes and an orifice mixing system. After examining the computed results it was found that the mass transfer efficiency of gaseous carbon dioxide into the water stream through the orifice mixing system was superior to that through the junction Venturi-tubes.

Supercritical Carbon

Numerical simulations of heat and mass transfer in supercritical carbon dioxide are carried out for natural convection conditions in a differentially heated square enclosure. The two vertical walls are maintained at different temperatures while the two horizontal walls are insulated. For the mass transfer studies, a heated vertical naphthalene wall is considered. Properties of supercritical carbon dioxide are evaluated from the National Institute of Standards and Technology (NIST) Standard Reference Database 12. A correlation for the mean Nusselt number along the heated wall is obtained as a function of the heat transfer Rayleigh number (for a given Prandtl number). A correlation for the temporal Sherwood number along the naphthalene surface is obtained as a function of the mass transfer Rayleigh number, and Fourier number (for a given Schmidt number). The results are compared with result available in the literature.
