| Abstract: | Taking account of latent heat of crystallization and heat dissipation along transporting route of waxy crude oil,the thermodynamic calculation was carried out in detail and the evaluation of frictional precisely,resistance of oil flow between oil heating stations with different flow patterns and flow forms was also conducted in detail.The influence of viscosity on pump efficiency was taken into consideration,also.The economical departure temperature from pump station was derived with mathematic model.The result showed that the overall operational cost would greatly be reduced and the economic benefits would be remarkable when the operational parameters were optimized for the crude oil pipeline on active duty. |
| Keywords: | waxy crude oil thermodynamic calculation hydrodynamic computation economical departure temperature |
