Title: Semi empirical models for selectivity of supercritical carbon dioxide for solid mixtures
Authors: Reddy, Sivamohan N.

Abstract: Selectivity of the particular solvent to separate a mixture is essential for the optimal design of a separation process. Supercritical carbon dioxide (SCCO 2) is widely used as a solvent in the extraction, purification and separation of specialty chemicals. The effect of the temperature and pressure on selectivity is complicated and varies from system to system. The effect of temperature and pressure on selectivity of SCCO 2 for different solid mixtures available in literature was analyzed. In this work, we have developed two model equations to correlate the selectivity in terms of temperature and pressure. The model equations have correlated the selectivity of SCCO 2 satisfactorily for 18 solid mixtures with an average absolute relative deviation (AARD) of around 5%. © 2012 Elsevier B.V.
