History[edit]

An IP contributor added some interesting background for natural gas, but it isnt very well written and is in fact copied straight from http://www.naturalgas.org/overview/history.asp . I think it would be a nice addition to this article, but it needs some major work to make it suitable for wiki. I refrained from deleting it because of this, but I suspect someone else may delete anyway due to COPYVIO :/. It would be really awesome if someone could fix it (I would do it myself but its not really my strong suit). I suspect some bits also need more references (oracle of delphi being due to natural gas, for example) but I'm sure references for something that significant would be easy to find (assuming that the company isnt lying).

I've removed the copyvio. You are welcome to use the link above and other sources to write a history section. However, copying directly from a website is not allowed. Vsmith (talk) 03:03, 15 September 2013 (UTC)
As I clearly said in the post above, I am aware of that. I was hoping that someone could fix instead of delete, but I guess that didnt happen. Benboy00 (talk) 10:01, 15 September 2013 (UTC)

Direct Health Effects[edit]

Came here to find out about direct health effects caused by normal exposure. Not much help from what I find. I live in Colorado US where marijuana has been legalized and there is some debate over one technique using propane and natural gas to extract THC for multiple products. Perhaps there are some political games being played in this matter, but would enjoy having independent review. Have noted for instance that some proponents seem to think that "Fracked" Natural gas is fine for energy use in homes, but when used to extract THC can cause health issues from petrochemical actions in the lungs.Fracking is being done heavily here, and yes water tastes terrible now, but am primarily interested in actual gas. There is the danger of course from explosions when using gas under novice operations but that is not what I am asking. Does Natural Gas cause adverse health effects from inhalation even when Carbon Monoxide is not at dangerous levels? Thank You. 208.123.153.190 (talk) 17:35, 5 June 2014 (UTC)

CNG/LPG cost[edit]

The article states that CNG is more expensive than LPG. Is it correct? — Preceding unsigned comment added by 87.68.74.113 (talk) 16:55, 20 June 2014 (UTC)

Confusion of condensate and natural gas liquid[edit]

"Condensate" as the term is used in the oil industry is what condenses at the surface in an ambient temperature separator. It is basically C5+ (pentane and a bit higher). Can be mixed into gasoline, even in the summer. It's essentially very high API oil, both chemically and economically. Think of it as the "associated oil" from a gas well. The way you would have associated gas with an oil well.

NGLs are the non-methane gases within a natural gas separated stream. They do NOT condense at a surface separator. You need a refrigeration plant to condense them.

The article says, "One method to deal with this problem is to re-inject dried gas free of condensate to maintain the underground pressure and to allow re-evaporation and extraction of condensates. More frequently, the liquid condenses at the surface, and one of the tasks of the gas plant is to collect this condensate. The resulting liquid is called natural gas liquid (NGL) and has commercial value."

You are confusing NGL and condensate and they are not the same thing. Condensate is mostly C5+, recovered at the wellhead. NGL is mostly C2-C4 (ethane, propane, n-butane, isobutene). Recovered at a refrigeration plant, away from the wellhead. Look up the boiling point of ethane! It is not condensing at the wellhead surface. Just no.

Please, no arguments about how any gas can become a liquid with cooling or the converse...or about how refrigeration plants have condensers. You are not helping your public who may have a very reasonable suspicion that NGL=condensate, by confusing the terms in article. In contrast, the block diagram under natural gas processing chapter explains this right.

Town gas is not natural gas[edit]

The section on 'town gas' should be removed. By definition, it is not 'natural' gas, as it it not extracted, but is manufactured. Jack B108 (talk) 13:59, 29 August 2014 (UTC)
