Abstract
The current research applies the recent graphical revamping methodology on an existing crude atmospheric distillation unit. The unit is located in north of Egypt (Suez region) and is operated under two different operational modes; (1) with naphtha stabilizer when LPG is separated from naphtha stream, and (2) without naphtha stabilizer when the process reformer is under run to reform all naphtha streams without stabilization. The unit processes 5,000 ton-per-day of crude oil coming from the Gulf of Suez. The current energy consumption is estimated to be 28.24 MW. Revamping of such plants is challenging and requires solution flexibilities. In this study, a simulation model and validation are initiated for heat exchanger network of two operational modes, using ASPEN ENERGY ANALYZER software, for energy analysis and optimization
