McCabe-Thiele Theoretical Stages Calculator

Step off theoretical stages on a McCabe-Thiele diagram for binary distillation. Calculate number of equilibrium stages from reflux ratio, feed quality q, and VLE data.

2D stress state at a point. All stresses in MPa.

σx — Normal Stress X (MPa)
σy — Normal Stress Y (MPa)
τxy — Shear Stress (MPa)
⚙ Mechanical Note: Results are based on standard textbook formulas and ISO/AASHTO references. Always verify critical designs with applicable codes (ISO 898, AASHTO 1993, AISC, Eurocode 3) and a qualified engineer.

How It Works

Step off theoretical stages on a McCabe-Thiele diagram for binary distillation. Calculate number of equilibrium stages from reflux ratio, feed quality q, and VLE data

Each component has a specific meaning:

  • Reflux ratio — The reflux ratio recorded for the scenario being assessed.
  • Feed quality q — The feed quality q recorded for the scenario being assessed.
  • VLE data — The vle data recorded for the scenario being assessed.

Note: Interpret the mccabe-thiele result against the thresholds and context described above.

How to Use

Enter the reflux ratio, feed quality q, VLE data for the scenario you are assessing. Step off theoretical stages on a McCabe-Thiele diagram for binary distillation. Calculate number of equilibrium stages from reflux ratio, feed quality q, and VLE data. Use the mccabe-thiele result to inform your calculation.
