摘要
针对低温LPG管道输送特点,在对该管道保冷层投资费用、制冷费用以及约束条件分析的基础上,根据费用最低原则,建立了计算保冷层厚度的数学模型。对该模型进行了求解分析,并编制了相应的计算程序,辅以实例说明了该程序的正确性。
The investment of pipeline insulation,cooling cost,and constraint conditions are analyzed in the light of the transmission characteristics of LPG pipeline. On the basis of the principle of the minimal total cost, a mathematical model is established,and meanwhile,a calculating software is developed. With a case,the model is proved to be correct and accurate.
