Kalina Binary Cycle Formulation:
• Variable Boiling Temperature Glide: ΔTglide ≈ 15 - 30 °C
• Distillation: Splits into rich vapor (xrich ≈ 95%) and lean liquid (xlean ≈ 40%)
• Net Power Output: Ẇnet = ṁvap · wturb − ṁbasic · wpump [kW]
• Thermal Efficiency: ηth = Ẇnet / Q̇in [%]
• Variable Boiling Temperature Glide: ΔTglide ≈ 15 - 30 °C
• Distillation: Splits into rich vapor (xrich ≈ 95%) and lean liquid (xlean ≈ 40%)
• Net Power Output: Ẇnet = ṁvap · wturb − ṁbasic · wpump [kW]
• Thermal Efficiency: ηth = Ẇnet / Q̇in [%]

📘 Calculation Methodology & Kalina Cycle Standards
Binary Temperature Glide
Because ammonia ($T_b = -33.3^\circ\text{C}$) boils before water ($T_b = 100^\circ\text{C}$), phase change occurs with a variable temperature glide matching the heat source slope, drastically cutting exergy destruction.
Distillation & Absorber Recombination
The high-pressure separator distills rich ammonia vapor for power generation, while lean liquid is recombined in the absorber to allow low condensing pressures at ambient temperature.
Key Engineering Assumptions
- Zeotropic ammonia-water binary mixture ($NH_3 / H_2O$).
- Dry rich vapor expansion without condensation in the turbine.
- Applicable to geothermal power, industrial waste heat recovery, and OTEC.
