Figure 10

Comparison of simulated lipid extraction yields (lines) and experimental lipid extraction yields (symbols) from microalga Nannochloropsis sp. [25] under different conditions. Red square, 2900 psi of pressure, 6.64×10⁻³ scfm of CO₂ flow rate, r² = 0.960; blue circle, 4350 psi of pressure, 6.64×10⁻³ scfm of CO₂ flow rate, r² = 0.931; green triangle, 4350 psi of pressure, 1.18×10⁻² scfm of CO₂ flow rate, 5 wt% of ethanol concentration, r² = 0.802; black inverted triangle, 4350 psi of pressure, 1.18×10⁻² scfm of CO₂ flow rate, 20 wt% of ethanol concentration, r² = 0.982.
