Abstract
Preliminary evaluations during flowsheet synthesis require simple effective tools for
comparison and elimination of process alternatives. This work investigates three areas
of interest in distillation.
Column profile map theory has simplified complex column investigations. The
predictions of the difference point equation at finite reflux were experimentally
verified for the acetone, methanol and ethanol system in a continuous column
apparatus.
Residue curve analysis is usually limited to systems with four components for
distillation system analysis. An alternative representation, based on combinatorial
topology and temperature sequencing, is introduced for use in high level synthesis
decisions for higher component order systems.
Attainable region (AR) theory is applied to an ideal binary distillation system for a
geometrically based method of cost analysis. A constrained attainable region is
constructed from a series of equilibrium step compositions with varying reflux and
corresponding cost associations. The AR is shown to be useful for costing and
optimization.
