The ν1 band of gaseous carbon dioxide has been studied in pressure-induced absorption at temperatures of ~ 190, ~ 300, and ~ 470 K, over a density range from 0.5 to 300 amagat, and with path lengths from 0.007 to 56 m. The observed temperature variation of the binary absorption coefficient can be satisfactorily accounted for only by adding a quadrupole–quadrupole interaction term to the usual Lennard–Jones model for the inter-molecular potential. The band profile is in agreement with the theory of quadrupole-induced absorption. There is some increase in the intensity of the band near the critical point due to the divergence of the correlation length. A very marked increase in the intensity is possibly prevented by the "cancellation effect".

Abstract An efficient enhancement of the carbonation rate in the bottle filling stage can substantially increase the production in beverage industries. The bottle filling system currently used in most of the manufacturers can still be improved for a better performance of carbonation by designing the injection tube system. This paper reports on an experimental and numerical mass transfer modeling that can simulate the dissolution process of gaseous carbon dioxide into aqueous water in the bottle filler system. In order to establish the operating characteristics of the bottle filler system, an ordinary tap water and pure carbon dioxide were used as the liquid-gas system. The two-phase numerical modeling was developed that can serve as a framework for the continuous improvement of the design of the carbonation process in the bottle filler system. For an optimal design of CO2 injection tube and flow conditions, a computational fluid dynamics (CFD) approach is one of the most power tools. However, since only limited experimental data are available in the open literature to verify the computational results, an experiment study was performed to obtain measurements of CO2 level, temperature, and pressure during the carbonation process in the bottle filled with liquid. Both experimental and numerical studies of various flow condition and different sizes of injection tube are presented in this paper.

CO2, being a linear and centrosymmetric molecule, is very stable, and the electrochemical reduction of CO2 requires energy. However, the salen complexes are found to be very efficient to minimize overpotential as compared to their metal counterparts.
