11.5.2 Extract
Extract is a rigorous extraction column simulation block. The material, energy, and
equilibrium equations given in equations (11.1) through (11.6) apply with the under-
standing that the vapor-phase nomenclature is fully appropriate for interpretation as
the second liquid. Because there are no phase changes, there are rarely large energy
