distillation.amundson_1958.main.make_ABC(V: numpy.array, L: numpy.array, K: numpy.array, F: numpy.array, z: numpy.array, Distillate: float, Bottoms: float, N: int)[source]

Distillation column with partial reboiler and total condenser

Note

K_j is assumed to depend on T and p, but not composition

Parameters

  • V – vapor molar flow rate out of stage 0 to N

  • L – liquid molar flow rate out of stage 0 to N

  • K – equilibrium expressions for stage 0 to N

  • F – feed flow rate into stage for stage 0 to N

  • z – feed composition into stage for stage 0 to N

  • Distillate – distillate flow rate

  • Bottoms – bottoms flow rate

  • N – number of equilibrium stages

Returns

A, B, C, D
