Natural Gas Pipeline Commissioning Displacement Nitrogen Injection Capacity Calculation Study

Abstract:

The article use the software of FLUENT to simulation nitrogen gas and natural gas section at different working conditions during the displacement course for commissioning of the pipeline. Then，use the MATLAB to analog data three-dimensional fit，the length of gas mixture segment can be calculate. According to the actual situation at the scene，give the formula a correction range. The formula of the nitrogen injection is based on the formula of the length of gas mixture segment. Drawn proven，consistent results with field data. The formula can meet the demand for pipeline safety commissioned. Research results to obtain reasonable assurance as to provide a theoretical basis for nitrogen injection.
