Thak you very much. You have been very helpful! :smile:

Hi- For years I have always known that Methyl Alcohol is used as a method of removing water from natural gas piping. For example - a pressurized natural gas pipe has a small amount of water trapped in it. The water, under certain flow, and temperature conditions will vaporize and cause...

Thanks for the ideas... I think I'm on the right track. The amount of water appears low. However, the actual pipe volume is very small. Still I've read that (for example) On a 75F day with 75 percent relative humidity, a 10-hp compressor can introduce 7 gallons of water into a compressed air...

? I was thinking of using the steam tables - partial pressure? What you are saying makes sense. Can you please confirm? Thanks again! JR

Hi- A recently installed natural gas main is showing evidence of water infiltration. Water is getting into the customers regulator and meter and freezing. The gas main was cleaned and "pigged" after the installation. The system is currently operating at an MAOP of 60 PSIG natural gas. When...

Great! Thanks... I appreciate your help. JR
