Density Correlation of Solubility of C. I. Disperse Orange 30 Dye in Supercritical Carbon Dioxide
Baek JK, Kim S, Lee GS, Shim JJ
The solubility of C. I. Disperse Orange 30 (O30) dye in CO2 has been measured by using a closed-loop (batch) solid-fluid equilibrium apparatus at temperatures between 313 and 393 K and at pressures between 11 and 33 MPa. Kumar and Johnston’s equation based on Chrastil’s concept has been used to describe the experimental solubility data. The solubility versus density plot appears much simpler than the solubility versus pressure plot. The isotherms are nearly straight and parallel to each other, as seen in the previous studies. Peng-Robinson equation of state (PR EOS) has also been used successfully in modeling the dye solubility in supercritical carbon dioxide as a function of pressure or density of the fluid phase. The validity of this method has been verified by the vapor pressure calculation.
Keywords: Solubility; Disperse Dye; Supercritical Carbon Dioxide; Peng-Robinson Equation of State
