| 摘 要： | 对于低温液化天然气输送管道,保冷层厚度的设计是防止管道内液体气化,实现液体单相流动的关键.文中以液化天然气管道年保冷层投资的分摊费用和运行费用之和为优化目标,同时考虑防止保冷层外表面结露,允许最大冷损失量,限制液化天然气进入冷却站温度3个约束条件,建立液化天然气保冷层厚度计算的优化模型,并用Visual Basic语言...

| Abstract: | For a LNG pipeline,the key problem is to prevent liquid evaporation,namely to realize the single-phase flow.Taking the total annual cost as an optimal object and considering the constraints at the same time,such as avoiding the emerging liquid globule,the quantity of maximal cold loss and the inlet temperature of the cooling station,the mathematic model is developed for designing the coldlayer thickness and the computing program is compiled by Visual Basic.An analysis of the example demonstrates the effecti... |
