Abstract |
In order to ensure safe and efficient operation of river crossing section of crude oil pipeline, it is necessary to study asphaltene deposition and evaluate long-term operation safety of the river crossing section. Based on findings of crude oil components and asphaltene deposition mechanism as well as complex flow environment of certain river crossing section, CFD method was used to study carrying effects of crude oil on asphaltene particles and transport process of these particles. Then deposition amount was quantitatively analyzed so as to evaluate safety of this section. The results show that transportation volume decreases by 0. 94% in river crossing section in terms of current current transportation technology, and it is in safe operation stage. © 2019 China Safety Science Journal.
