摘要
成品油管道设计优化以往大多集中在对管径、壁厚、泵站数、进出站压力等工艺参数的优选,对影响混油量的因素考虑不多。介绍了顺序输送成品油管道产生混油的影响因素,包括:管内流体沿径向流速分布不均匀,管内流体沿径向、轴向的紊流扩散,站场工艺管道的"死区""盲肠"等部位滞留油品,管道沿线地形起伏,不同油品的密度差,输油生产过程中的停输等。根据国外的先进经验,以减少混油量为目标,从6个方面论述了成品油管道的优化设计方案,包括泄压罐的设置、阀门的位置确定、收发球筒的口径和连接管路的设计、启泵方式的选择、站内工艺管道管径的设计以及管输介质雷诺数参考值的确定。
In the past time,the optimal design for products pipeline focused on finding the optimal points of station parameters such as pipe diameter,thickness,numbers of pump stations,suction/discharge pressure,etc..It seldom took the impact factors of oil blending into consideration.The paper briefly introduces the impact factors for oil blending in batch products pipelines as follows:the non-uniform distribution of the vertical fluid velocity;the turbulent diffusion of the fluid flow in both vertical direction and axial direction;the resorted oil in dead section;the elevation difference;the density difference for varied batches;the potential shut-down of the pipeline,etc..With reference to the advanced experiences from international pipeline operating companies and taking cutting down the contaminated volume as a subject,the optimal design program are discussed in the allocation of relief tank and valves,the design of pig launcher/receiver's diameter and their manifold,the starting-up way for pump units,the diameter design for station pipeline and Re number for transported medium.
