📐 Key Calculations

Terminal Droplet Velocity

v_t = √(4g(ρ_l−ρ_g)d_p / (3C_dρ_g))

Result: 0.18 m/s

Determines minimum vessel height for droplet settling

Gas Capacity Constraint

Q_g = A × v_g

Result: 12,500 Sm³/h

Sets maximum allowable gas throughput

📊 Results

99.7% liquid removal efficiency; 0 compressor trips over 18-month operation

💡 Lessons Learned
