采用SPS仿真软件建立某天然气长输管道的物理仿真模型,基于模型具有一定精度和可靠性的基础上,利用其特有的短管组件模拟空冷器来进行出站温度调节,分析出站温度调节对输量的影响。分析研究结果表明,当天然气出站温度低于42℃或介于70-80℃时,出站温度调节对输量影响很小,当天然气出站温度介于54-70℃时,出站温度调节对输量影响较小,因此都不利于冷却输送。当天然气出站温度介于42-54℃时,出站温度调节对输量影响较大,利于冷却输送。当天然气的出站温度为40℃和70℃时,输量的增加量为21.12×104m3/d,即单位天时间内管道的输送能力提高21.12×104m3。
The physical simulation model of a natural gas long distance pipeline is established by using SPS simulation software. Based on the model’s accuracy and reliability, the out-of-station temperature adjustment is simulated by its unique short-tube module to simulate the out- The impact of the volume. Analysis results show that when natural gas exit temperature is lower than 42 ℃ or between 70-80 ℃, outbound temperature regulation has little effect on the output. When the natural gas exit temperature is between 54-70 ℃, the outbound temperature Adjustment of the impact on the smaller, so are not conducive to the cooling delivery. When the natural gas exit temperature is between 42-54 ℃, the outbound temperature adjustment has a great influence on the output, which is good for cooling and conveying. When the exit temperature of natural gas is 40 ℃ and 70 ℃, the increase of output is 21.12 × 104m3 / d, that is, the delivery capacity of pipeline in unit days is increased by 21.12 × 104m3.
