稠油输送管道掺0#柴油运行费用优化

以两站间密闭稠油掺0#柴油集输管道为研究对象，建立数学模型，对管道总运行费用中的变量进行优化计算，讨论掺入不同比例0#柴油对管道运行费用的影响。稠油添加0#柴油后，管输摩阻损失降低，所需泵扬程及耗电量减少。当设定进、出站油温时，影响稠油管输费用的因素包括添加0#柴油原料费及泵的电费，而0#柴油原料费起决定性作用。以某混合稠油掺0#柴油管道为例，计算0#柴油不同掺混比例下的运行工况和费用，经对比分析，确定了经济输油方案。（表4，图1，参7）

Operation cost optimization of pipeline transport of heavy oil blended with 0# diesel oil

Taking the tight line gathering pipeline of heavy oil blended with 0# diesel oil as a research object, a mathematical model is established to optimize the variables in the pipeline＇s total operation cost and analyze the effect of 0# diesel oil ratio on the pipeline＇s total operation cost. After adding 0# diesel oil into heavy oil, friction loss in pipeline decreases, therefore the pump lift needed and electricity consumption are reduced. At set inlet and outlet oil temperatures, factors affecting the total cost of heavy oil pipeline include raw stock cost of 0# diesel oil which plays a decisive role in the total cost, and electricity charge of pumps. This paper, taking the pipeline of heavy oil mixed with 0# diesel oil as an example, calculates the operation conditions and total cost at different 0# diesel oil ratio, and figures out the economical oil transport plan through comparison. （4 Tables, 1 Figure, 7 References）
