摘要

The various considerations that went into the total design of the crude preheat train and various other heat exchangers are described in detail. Since there were a total of 8 cases of operation, optimisation was a crucial issue. Pinch technology was employed to full advantage in synthesising the crude preheat train as well the BFW circuit. Reboilers were integrated with the crude preheat train but the overhead condensers had to employ cold utilities. Downstream of the crude preheat train, hot products were used to generate steam and preheat BFW before going to air and/or water coolers. Some interesting features of thermal design of the individual heat exchangers arc also highlighted.
