Abstract
Distillation columns are among the most energy-intensive units in refineries. This study presents a tray-by-tray exergy analysis of the
catalytic-reforming stripper column at Abadan Oil Refinery under steady-state conditions using Aspen Plus v12. The feed tray, condenser, and reboiler were identified as the main sources of exergy destruction, accounting for 28%, 20–28% and 15% of total losses, respectively. Sensitivity analysis showed that feed temperature and reflux flow have the greatest influence on exergy efficiency. Their simultaneous optimisation reduced total exergy destruction by up to 34% and improved exergy efficiency by approximately 8.5%.
