Study on the Simulation and Experimental of Natural Gas Cold Venting
Natural gas venting is an important part of the production and operation process of gas pipeline,which is a complex process in which pressure,temperature and venting flow rate all change with time.Based on the actual situation of the venting pipeline,the calculation method that is recommended is improved and perfected by the relevant specifications.The model takes into account the venting calculations of the critical flow and subcritical flow at the outlet,the effects of the venting pipe valve opening and the internal energy changes caused by the expansion of natural gas on the venting of the pipeline are studied.The calculation results of the model are generally consistent with the actual pipeline venting data,which provides technical support for future production scheduling and accident repair.
