摘要

Debottlenecking of atmospheric crude distillation unit of a Niger Delta Refinery (NDR)with aPetrochemical Unit, was carried out using pinch technology. This case study was aimed at improving the heatrecovery and operational efficiency of the system.From the analysis, the pinch point was located at 247 oC witha target minimum heating and cooling duties of 80MW and 32MW respectively. The base case heat exchangernetwork performance indicated that the heating and cooling duties were above the target by 26% and 67%respectively. The result obtained from the debottlenecked heat exchanger network revealed energy savings of41.32 MW which translated into 89% rate of return on investment.The pinch analysis showed that the actualheat exchanger network of the atmospheric crude distillation column was not efficient due to energy transferbottlenecks caused by some cross pinch heat exchangers.
