Studies on Heat Integration in Crude Preheat Train and the Effect of Fouling

This report is on the performance of heat exchanger in Crude Preheat Train and the effect of fouling. For years refinery had been struggling with various operational problem due to fouling. This project uses two different Crude Preheat Train design. The simulation work will study the difference in the performance of each heat exchanger in the preheat train both under clean and fouled condition. This project use Aspen Hysys 2006 software. The importance data in this project is the overall heat transfer coefficient and the duty of the heat exchangers. The result shows the advantage and disadvantage of both preheat train design. This project also looks into the economic impact of fouling on the preheat train. Results show the advantage and disadvantage both preheat train design. Simulation and calculation data are documented to provide a base for future work on possible reallocation of streams in the existing Crude Preheat Train.
