锯齿形曲线与原油长输管道热厡站布置

The Zigzag Curves and the Arrangement of Heating Pump Stations on a Crude Oil Pipeline

  • 摘要: 加热输送的原油管道,其运行费Co s t(指电费CE与油费Co之和)与输油温度Td(出站)、Ts(进站)的关系曲线呈铅齿形分布。根据这一分布规律,采用一定的优化方法可使布站工作得到改善,从而避免了水力坡降线法布站租精且计算工作量又大的缺点。文中详细地介绍了锯齿形曲线的产生及其实用喜义,应用钴齿形曲线布站的方法及电算程序框图。同时还分析了管径、输量、管长、油品粘度, 运行压力、油价和电价对锯齿形由线分布规律的影响, 对合理选择输油湿度及经济运行有一定的适用意义。

     

    Abstract: In the case of a pipeline carrying heated oil, its operating cost (here it refers to the sum of power cost CE and oil cost Co) and the input oil temperature Td and output oil temperature Ts are related to one another in a zigzag distribution curve. Following this distribution law, the arraugement of pump stations can beproved by application of optimization method, thus avoiding the roughness and bulk work at calculation as it is by using the hydrodynamic gradience for arragncment of pump stations. The article explains in detail the introduction of the zigzag curve and its practical significance, the way to use it for arrangement of pump stations and the diagram of computering programmes. Meanwhile analysis is made of the effects of pipe diameter, throughput, pipe length, oil viscosity, operating pressure, oil cost and power cost upon the distrbution law of the zigzag curve, which is of some practical significance for rational selection of the proper carried oil temperature and economical operation of oil pipelines.
