Congelation Risk Assessment of Oil Pipeline on Basis of Improved Monte-Carlo Method

Abstract:

Congelation accident in pipeline of crude oil is always being a serious problem in china, which is mainly determined by the properties of domestic crude oil such as high content of wax, high pour point and viscosity. When oil pipeline operates at low throughput or shutdown, congelation accident always happen as the temperature of oil drops, which causes malignant accidents and significant financial losses. Using improved Monte-Carlo method of reliability theory, the failure possibility of congelation was numerically calculated. Whereas, the consequences of congelation accident were also fully analyzed, these can provide evidences for accident treatment, planned maintenance, security operation and scientific management.
