Chrastil SFE Formulations:
• Chrastil Solubility: S = ρCO2k · exp( a/T + b ) [g solute / kg CO₂]
• Extraction Rate: ṁext = ṁCO2 · S [g/h]
• Extraction Time: t = 0.90 M₀ / (ṁCO2 · S) [hours]
• Specific CO₂ Demand: mCO2 / mextract [kg/kg]
• Chrastil Solubility: S = ρCO2k · exp( a/T + b ) [g solute / kg CO₂]
• Extraction Rate: ṁext = ṁCO2 · S [g/h]
• Extraction Time: t = 0.90 M₀ / (ṁCO2 · S) [hours]
• Specific CO₂ Demand: mCO2 / mextract [kg/kg]

📘 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 · ln ρ + (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.
