Thermal Integration of a Distillation Column through Side-exchangers
نویسنده
چکیده
Invariant rectifying and stripping (IRS) curves are used for thermodynamic analysis of a distillation column. Thermal integration of a distillation column with the background process through side exchangers (side reboilers/condensers) is important for energy-efficient design of a distillation column. Thermal integration of a distillation column through side exchangers also improves the exergetic efficiency of the column. Different configurations of side-exchanger integration are evaluated based on the exergetic efficiency of the distillation process and they are also compared with feed preheating options. It has been observed that thermal integration by feed splitting is the best thermodynamic option.

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....
