🧪 Binary Distillation Column Design

An interactive Streamlit app to visualize the McCabe-Thiele method for binary distillation.
This tool helps you understand how operating lines, and feed conditions determine the design of a distillation column.

📌 Features

• Interactive sliders for:
  • Feed composition (xF)
  • Distillate composition (xD)
  • Bottom composition (xB)
  • Reflux ratio (R)
  • Relative volatility (α)
• Assumes q = 1 (saturated liquid feed)
• Plots:
  • Equilibrium curve
  • Rectifying section line
  • Stripping section line
  • Feed line (vertical, since q = 1)

🧮 Operating Line Equations

Rectifying Section:

y = (R / (R + 1)) * x + xD / (R + 1)

Stripping Section:

y = ((y_int − xB) / (xF − xB)) * (x − xB) + xB

Flow-based Stripping Line:

y = (L′ / V′) * x − (B / V′) * xB
