长输热油管道运行优化技术

对于长输热油密闭输油管道，当输量和油品性质一定时，寻求全线热站和泵站（热泵站）的升温、升压值的最佳组合以使全线的能耗费用最低，是长输热油管道运行方案优化的目标。文章结合盘锦输油管道实际，根据能量平衡原理，建立长输热油管道运行优化的数学模型，采用组合优化方法，利用计算机进行编程、计算，给出了运行方案的最优工况。方案实施结果表明，盘锦线运行总能耗降低32％。

Optimization Technique of Long-distance Hot Oil Pipeline Operation

For long-distance hot oil closed transmission pipeline,its operation scheme optimization objective is to seek the optimal combination of increased temperatures and pressures at heating stations and pumping stations of whole line under states of steady transmission volume and stable oil properties in order to minimize the whole line energy consumption costs.Combined with the operation practice of Panjin Pipeline,the optimal operation scheme is obtained through the following steps:establishing optimization ma...
