Abstract:
In order to evaluate the performance and select the filtration and separation equipments used in natural gas distribution station,a particular pressure reducing device was designed by using throttling effect.An on-line dust measurement method in high-pressure natural gas pipeline was proposed.Numerical calculation and experiment result show that there is no liquid droplet generated during pressure reducing.The influence of the pressure-reducing device on particle concentration and size distribution can be ignored.The method of dust on-line measurement in high-pressure natural gas pipeline is accurate and reliable.

摘要:
针对高压天然气管道分输站场用过滤分离设备性能评价和设备选型的要求,利用小孔节流效应设计了适合高压管道取样用减压装置,在此基础上提出了高压天然气管道内粉尘在线检测方法。采用数值计算与现场试验相结合的方法,验证了粉尘在线检测方法,结果表明减压装置减压过程中无液滴析出、对粉尘浓度和粒度分布影响小,在线检测方法检测结果准确可靠。
