Dear all.

 

I am in charge of operating and managing gas pipeline.

 

I have  questions about pipeline purge.

 

Here is my questions.

 

- After completing pipeline construction, we will serve natural gas in new pipeline.

 

  Normally, we follow up the procedures as below.

  a) pipeline completion  -> nitrogen purge -> c) natural gas service and compression.

 

  However, we will add dried-air purge to remove remanent water in pipeline.

  a) pipeline completion -> dried-air purge -> c) nitrogen purge -> d) natural gas service and compression.

 

  In this case, I am concerned about the increase of possiblity of explosion due to residual dried-air in pipeline, which pressure is higher than  

  atomspheric pressure.

 

  My question is whether dried-air purge is appropriate measure in aspect of safety.

  And is there better way to remove remanent water in pipeline?

 

  thank you..
