摘要:
针对输气管道投产中氮气置换主要依据经验以及存在较大盲目性的问题，采用 Fluent 软件对氮气置换过程中氮气在空气中的对流扩散情况进行了多工况数值模拟，分析了混气长度的影响因
素。结果表明：流态、背压、流速、管径和管长是影响混气长度的 5 个因素，其中混气长度随着背压、流速、管径和管长的增大而增长；与氮气处于湍流时相比，氮气处于层流时的混气长度大，置换时间也长得多；投产时，应尽量放空以减少背压对管道投产置换的影响。研究结果可为确定合理的用氮量和现场投产实践提供理论依据，对于优化输气管道的投产运行具有指导意义。
Abstract:

The nitrogen purging & packing of gas pipeline commissioning is mainly determined depending on the experience，so there is great blindness. With FLUENT software，the convective diffusion course of nitrogen in air at different working conditions is simulated during the nitrogen purging & packing course of different gas pipelines. The influencing factors of gas-mixing length are analyzed. Results show that flow pattern，back pressure，flow rate，pipeline diameter and pipeline length are five influencing factors in the gas-mixing length. The gas-mixing length grows with the increase of back pressure，flow rate，pipeline diameter and pipeline length. The corresponding gas-mixing length and time for the nitrogen are longer when it is at laminar flow. The simulation results are consistent with the experimental results. The research results are instructive for optimizing the commissioning of gas pipelines.
