New pipeline profiling method helps avoid condensation, black powder

A new method can help avoid condensation and control hydrates in the early stages of a natural gas transmission pipeline’s life, thereby helping avoid future black powder formation.Locating areas in natural gas transmission pipelines susceptible to condensation of water vapors and higher hydrocarbons, hydrates, and black powder formation, require both temperature and pressure profiles for the gas traveling through these pipelines.
