Safe Purging of Natural Gas Pipelines
T. K. Perkins and J. A. Euchner
When a newly constructed natural gas pipeline is put into service, it can be safely purged of air by injection of a slug of inert gas, such as N2. The method of sizing the required slug is based on a model of dispersion in turbulent flow in conjunction with flammability limits.
