Abstract
SFEModeling.jl is an open-source Julia package for fitting kinetic models of supercritical fluid extraction (SFE) to experimental extraction curves. It implements the Sovóvá broken-and-intact-cells model, solved numerically along the extraction bed, together with a pseudo-steady-state shrinking core model and four empirical models (Esquível, Zeković, parallel kinetics, and a piecewise-linear spline). Several curves, each with any number of replicates, are fitted jointly. In the Sovóvá model the accessible-solute fraction xk/x0 is shared across curves while the mass-transfer coefficients are estimated per curve. Parameters are found by derivative-free global optimization, so no initial guesses are required. Data and operating conditions are entered in laboratory units, and results can be exported to text or Excel files. The same functionality is available from a browser-based graphical interface, distributed with a Windows installer and as a Julia app, so experimentalists can use the software without programming.
