Design procedure for a plate-to-plate heat-integrated distillation column.

DEVELOPING A NEW INITIALIZATION PROCEDURE FOR DISTILLATION COLUMN SIMULATION

  The simulation of distillation columns is an essential step in design, optimization, and rating. In this paper, a new procedure has been proposed for the initial estimation of column profiles based on modified Kremser’s group method for simple and/or complex columns. The effect of this initialization algorithm on simulation procedure has been studied through two examples. The results show sig...

The Design and Optimization of Distillation Column with Heat and Power Integrated Systems

Based on two integration steps, an optimization framework is proposed in this work for the synthesis and design of complex distillation sequence. The first step is to employ heat integration in sequence and reduce the heat consumption and total annual cost of the process. The second one is to increase the exergetic efficiency of sequence by generating power in implemented expanders in sequence....

A thermo-hydraulic approach to conceptual design of an internally heat-integrated distillation column (i-HIDiC)

This paper presents a new approach to the conceptual design of internally heatintegrated distillation columns (i-HIDiC), based on column temperature profiles analysis. The paper proposes tools to assess the thermal feasibility of i-HIDiC designs and to determine whether the design and operation are feasible from the hydraulics’ point of view.
