摘    要:基于输油工艺的实际情况,以进站油温为变量,给出了一定输量及稳态条件下密闭输送原油管道泵管耦合运行的目标函数和约束条件,应用非线性规划方法和逐站工艺计算,实施了全线运行方案的优化分析。计算结果表明,采用该方法可直接得到给定输量下管道各站泵炉的运行方式、加热温度、出站压力等运行控制参数以及包括经济指标等内在的最优运行方案,以供实际工程参考。

关 键 词:输油管道  运行优化  数学模型  非线性规划  目标函数  约束条件

Abstract:Based on the technique practice and take the inlet temperature of oil as a state variable, the object function and constraint for oil pipeline with tight line transport process are outlined under the stability condition at given discharge rate. The optimization analysis is performed by the nonlinear programming method. The economic operation scheme is obtained by means of detail station-by-station numerical calculation according to the transportation requirements. The analysis and calculation results show that the optimization scenario can be used for some 902-km-long oil pipeline with 19 pumping stations. With this operation scenario, the operating way of pumps and heaters, heating temperatures and outlet pressures for each pumping station can be directly obtained, also including the optimal operation scenario with economic indexes, which can provide to other oil pipeline to reference.
Keywords:crude oil pipeline  optimal operation scenario  mathematical model  nonlinear programming method  calculation  analysis
