| dc.description | Wax deposit is one of the main problems facing crude oil transportation pipelines, especially the waxy crude oil types. This problem usually appears at different temperatures where the wax crystal lines start to deposit at certain conditions causing plugging the production lines and viscosity increase, consequently leading to increasing the required power for flowing. And fluid pressure which may cause the pipeline to coming environmental and economic losses. The current study introduces several scenarios to simulate a ground crude oil pipeline, 1016 mm (40 inches) diameter and 212 km length burred underground along the distance in depth of 1.5 m. This pipeline is transporting a waxy crude oil with pour point of 39 °C. The software for used this simulation is (HYSYS 3.2), is out in two parts:- The first part investigates changing the crude oil flow rate down to the minimum flow rate that the pipeline may operate That is, the arrival temperature should be higher than the pour point. The second part investigates pipeline shutdown simulation to check the temperature profile along the pipeline and pin points the lowest temperature reached with time changing. The results of the first part determine the minimum flow rate allowed ,i .e, 79000 barrel/day at which the temperature will be higher than the pour point (39 °C), The maximum flow rate used in the simulation was 104000 barrel/day. The results of the second part, where the maximum time specified as 96 hours and other times were (24, 48 and 72) hour, respectively, it was found that the most safe time for shutdown at low temperatures without wax appearing is (3,5and 6) hours at different ambient temperature (4,10and15°C) respectively. | |
