Natural Gas Dehydration System (Using Glycol)

Natural gas dehydration systems are commonly used in midstream applications as well as upstream applications where gas is compressed or produced at high pressures. In this video, ARC Energy partners with Oilfield Basics to explain not only how the system works, but also to show all of the major components.

Incredibly interesting video. Thanks!

[@bestfriendhank1424]

Thanks for the video. In depth and interesting, but not a bore.

Love to see a video on the building or the maintanence of this systems

Holy smokes! This was sooooo good. I recently interned at a midstream company (natural gas) & I wish I would of found this sooner. You touched on a lot of key items and explained them in a nice simple way. Keep up the good work!

great video , educational and simple

[@OilfieldBasics]

Thank you!

[@thiagomarins1231]

Very good. Congratulations.

hey quick question whats the different between a glycol contactor vs stand alone scrubber? the scrubber just takes the water out?

Woah

Fascinating video, as a crude hauler sometimes I open a crude holding tank thief hatch and there's so much gas/pressure it blows my hard hat off my head. Always happens on hot "fresh" oil during flowback immediately following frac completion, and or hot summer days, would it be accurate to say this is natural gas which hasn't had the time to burn off via flare stacks, the absence of a dehydration system, or BTEX's pumped back in, or just some other pressure issue within the holding tank battery separation /dehydration system?

[@OilfieldBasics]

Good question. That's largely going to be what we would call flash gas. As the oil dumps to the tanks from a higher pressure vessel, gas comes out of solution. Warm temperatures would also cause more gas to come out of solution from the oil. The gas should get combusted or recovered, but on warm days or days where production is high, the average tank pressure might be higher. This has nothing to do with a dehydration system.

Just checked it out, nailed it. 👌 grateful for your videos, keep em up !
