Thermodynamic Analysis Of A Crude Oil Distillation Unit
Keywords:
Thermodynamic analysis, exergy loss, exergy rate, KEY WORDS: Thermodynamic analysis, exergy loss, exergy rate, efficiency.Abstract
Crude distillation unit is an essential part of the crude oil refinery system and it is an energy intensive process. This work presents a thermodynamic analysis of the unit with the aim of improving its efficiency. HYSYS was used in simulating the crude distillation unit at its operating conditions. The overall efficiency was found to be 31.98%. Exergy loss profile and exergy rate diagram on a tray by tray level were used in assessing the column for regions of high entropy generation. The result shows the feed tray to be a region of high exergy loss. Modification of the feed conditions will therefore improve the efficiency of the column.
