Question regarding flammable material reacting to anything that touches it
Posted on 6/28/17 at 5:30 pm

This might be simple to answer but Im not really a science guy so here goes. We picked up 6k gals of natural gas condensate/water mixture today and everything seemed normal when looking at it. But when we went to sample the material, it started instantly bubbling once the surface was broken. At first we went to sample with an aluminum sample tube and it instantly bubbled. So then we tried a plastic sampling tube and same reaction. So then I inserted a wooden measuring stick and the same thing happened again.
What has me stumped is the fact that the material will be perfectly calm, but once the surface is broken it starts bubbling. As you put the sample tube further into the tank, it bubbles more and more, where it basically looks like its boiling (but obviously not). But once you remove said object, it instantly stops. Does this have to do anything with the atmospheric pressure of the material? Or am I way off here?
Thanks in advance for the help.

Co2 ? Ch4 +O2 = 4H2O + Co2

That's the most puzzling part of this story.

While it might sound redundant, its just a mixture of gas and water.

Gas breaking out of the water?

Yea. The surface tension on the water is probably enough to keep the gas in suspension and breaking it allows it to start bubbling.

I think it is a reaction to the different temperature of the sampling materials.
What temperature is your condensate?

you ever hear of something called oxygen?

I can make bubbles with gas and water

I think that would make sense. But Im also wondering if it has anything to do with the outside temperature as well. We took a sample around 1pm and the sample has now sat for a few hours inside the office. I just put a pencil inside (to mimic the wooden measuring stick) the sample bottle and no reaction. So I then put an ink pen (to mimic the plastic sample tube) inside and once again no reaction.

It's like CO2 in soda, the trapped gas doesn't have the energy to break surface tension on its own, but when you stick the probe in that breaks the surface tension and allows the gas to escape. Plus the sample tube has microscopic pits that the trapped gas can enter and that lets it expand, that's why it looked like it was boiling when you stuck the tube further in. Same principle that causes the rapid release of CO2 when you put Mentos in Coke. That's why it's happening, what it means, no clue.

The higher the atmospheric pressure the higher the surface tension which means gasses that would normally escape, can't.

Why would there be higher atmospheric pressure? If you're at sea level or 200' higher you would still be at 1atm...I don't see how any place at ground level in La would significantly increase surface tension.

That's some funny shite right there.
