๐ Calculation Methodology & Chrastil SFE Standards
Chrastil Density-Based Model
Solute solubility in dense gas is directly related to the fluid density $\rho$ raised to the association number $k$ of solvent molecules forming a solvato-complex:
ln S = k ยท ln ฯ + (a / T) + b
Sovova Extraction Kinetics
Extraction proceeds in two phases: solubility-controlled constant extraction from broken surface cells, followed by internal diffusion from intact plant vacuoles.
Key Engineering Assumptions
- Critical point of carbon dioxide: $T_c = 31.1^\circ\text{C}$, $P_c = 73.8\,\text{bar}$.
- Equilibrium saturation of $CO_2$ exit stream in early batch phase.
- Total separation in depressurization cyclone flash vessel.
