掺氢对天然气管道工艺参数影响的模拟分析
Simulation analysis of the influence of hydrogen blending on the process parameters of natural gas pipelines
摘要
Abstract
Due to significant difference in physical properties between hydrogen and natural gas,hydrogen blending will have a great impact on the process parameters of natural gas pipeline.This study systematically explores the influence of different hydrogen blending ratios on the process parameters of natural gas pipeline under high-pressure conditions.The effects of 0～30%hydrogen blending ratio on the hydraulic conditions,throttling effect and centrifugal compressor operating characteristics of natural gas pipeline transmission were simulated using HYSYS software.The changes in operating parameters were then discussed and analyzed.The results show that the hydrogen blending increases the outlet pressure and pipeline volume flow rate while reducing the gas transmission power.When the pressure drop remains constant,increasing the initial pressure has a better effect on improving the gas transmission power.The Joule-Thomson effect caused by throttling can be suppressed by hydrogen blending.Studying the change of transition pressure and temperature after throttling helps select an appropriate hydrogen blending ratio.Maintaining constant speed,hydrogen blending decreases the performance of centrifugal compressor,reducing the pipeline gas transmission capacity.The research results provide an effective reference for the determination of relevant process parameters after hydrogen blending in natural gas pipelines.关键词
