Analysis and conceptual design of ternary heterogeneous distillation processes
Industrial & Engineering Chemistry Research, 2002, 41, 3849-3866
Design phenomena in heterogeneous distillation processes are investigated. Algorithms for tray-by-tray calculation are extended for columns with multiple heterogeneous trays in both sections. Minimum energy calculations and methods for feasibility analysis are investigated for such systems. Based on this research, a new conceptual design method for heterogeneous distillation with one feed and two product streams is developed and tested on several examples showing different residue curve map topology.
