Jae W. Lee, Stefan Brüggemann, Wolfgang Marquardt:
Shortcut method for kinetically controlled reactive distillation systems
AIChE Journal, 2003, 49(6), 1471-1487
Abstract:
This article addresses a geometric-based shortcut method for reactive distillation.
The
rectification body method for non-reactive distillation (Bausa et al, 1998 and Watzdorf
et al., 1999), the concept of critical Damköhler numbers (Buzad and Doherty, 1994),
and the geometric design method for reactive distillation (Lee et al., 2001a,b) are
combined with a new eigenvector analysis of pinch points. This shortcut method
provides us with a minimum or reasonable Damköhler number for a given heat duty.
Also, the shortcut results give us the design implication of how to effectively distribute
reaction zones inside a column. This method can be used for a fast screening of process
design alternatives and for an initialization of rigorous optimization.
