Specification of Flowsheet in Aspen Plus. Using Aspen Plus to develop rigorous simulations of single distillation columns and sequences of columns, the book considers the economics of capital investment and energy costs to create an optimal system for separation methods in the chemical and petroleum industries. • Learn to troubleshoot distillation column models, enhance convergence, and evaluate model quality. of column composition with time in the column. Learn how to simulate complex features in distillation processes, including azeotropic, three-phase, and reactive distillation as well as columns with features such as pumparounds, side draws, multiple condensers, etc. Modeling and simulation of batch distillation unit Aspen Plus, Aspen HYSYS, ChemCad and MATLAB, PRO/IITM etc. Analysis and optimization of two-column cryogenic process.
