“…In the former, the K(1) are obtained from the composition in both the extract and raffinate, S I = SC-CO,, i from 1 , 2, ...., to 16 Y ( l ) = 1. The experimental y(1) and x(1) are obtained from fluid-liquid equilibrium data by either the static or dynamic method, (King et al 1983; Lahiere and Fair 1989). An alternative method to calculate K(I) is adopted from the equation of state.…”

A mathematical model was developed for continuous extraction of multicomponent mixture anhydrous milk fat (AMF) with supercritical carbon dioxide (SC‐CO2) as its solvent. At a constant temperature and pressure, the triglyceride mixture was separated into vapor and liquid fractions. the composition distribution (indicated by acyl carbon number), mass distribution and yield of AMF were calculated by the model based on thermodynamic equilibrium and material balance. the feed composition and distribution coefficient were required information in this model. the experimental values for the extract were in good agreement with the model used. the results for the raffinate were not as precisely modeled. the main factors which affected the model were temperature, pressure, solvent/feed ratio and extract fraction.

A high-pressure phase behavior apparatus is presented in this paper. One new feature of the apparatus is a "rodded cylinder", which greatly simplifies the equipment design. This experimental apparatus is capable of performing vapor-liquid equilibrium tests at pressures up to 40 MPa and temperatures up to 150 °C. Test runs of the apparatus have been made to study the phase behavior of CO 2 -containing binary and ternary fluid mixtures. The measured compositions of equilibrium vapor and liquid phases are in good agreement with those reported in the literature. This apparatus is useful for generating data required for process designs of supercritical fluid extraction.
