Impact of Non-Hydrocarbon Impurities on Dense Phase Natural Gas Pipelines

Natural gas may encompass diverse non-hydrocarbon impurities such as nitrogen, carbon dioxide,hydrogen sulfide, hydrogen, and argon. The performance of the natural gas pipeline is notably influenced bythese impurities, affecting both physical properties and operational conditions. This study delves into themaximum presence of these impurities in typical natural gas, examining their impact on pipeline performancein both dense and supercritical phases. Additionally, a comparative analysis between the dense and supercriticalphases and the vapor phase was conducted. The findings reveal that a ۱۰% presence of nitrogen in natural gasexerts the most significant impact, while ۰.۰۲% hydrogen and ۰.۰۵% argon have the least influence on pipelineperformance in dense and supercritical phases
