Talk:Liquefied natural gas

WP has an article of the same name

Wikipedia has an article of the same name. This article was completely written from scratch ... altho it may have a few words or even a few sentences that are the same as in the WP article. Milton Beychok 20:38, 22 February 2011 (UTC)

Conversions

In this part:

1 metric ton (MT) = 1 tonne = 1,000 kg = 2,204.6 pound = 1.1023 short ton (ton)

If a short ton is 1,000 pounds as indicated further down in the article, shouldn't this be 2.204.6 short tons? Is the short ton supposed to be 2000 pounds? David E. Volk 14:22, 23 February 2011 (UTC)

Yes. a short ton is 2000 pounds and a long ton is 2,240 pounds. I fixed my typo that you found. Thanks. Milton Beychok 19:14, 23 February 2011 (UTC)

Distillation

Milt, could you give more detail regarding the distillation process? Is the methane distilled away from the ethane, propane, butane because it has a lower boiling point? Or are the methane, ethane, propane and butane all distilled together away from the other gases, for example, leaving behind any pentanes, heptanes, hexanes, grease etc. David E.

David, as you may have noticed, my block flow diagram refers the reader to Natural gas processing, where a much large and more detailed flow sheet shows how the natural gas is purified before it is liquefied. I also included a wiki link in the article text to Natural gas processing. I had thought that was sufficient, but I know now that it wasn't. So I have added a sentence or so to explain the distillation train. Thanks for your review. Milton Beychok 17:08, 23 February 2011 (UTC)

Safety

Henry, thanks for your detailed review. I am going to remove one of your edits, the one in the lede that reads "... although upon contact with an oxidizer such as air or oxygen, LNG can become extremely flammable or even explosive." because that it is not strictly correct. LNG in its liquid form is neither flammable or explosive. When it vaporizes and becomes a gas, then it becomes dangerous.

As soon as I can find time, I will add a new section to this article to discuss the safety aspects in detail. It was an oversight on my part not to include such a section. Milton Beychok 17:08, 23 February 2011 (UTC)

On a related note...in the introductory section, it is stated that LNG is not toxic. Are there no caveats at all that need to be appended to this general statement? As a layperson, I would have thought that exposing people to LNG in an unventilated room, for example, might be a bad idea? Isn't one supposed to call the fire department, for example, "if you small something like rotten eggs" as the folk wisdom goes? Forgive my ignorance, just checking!

My guess is that it must mean so long as it stays liquefied it's non-toxic, i.e. presumably it's safe to drink (if not very tasty). If that's not what it means, or maybe even if it is, the wording might do with soem clarification. Peter Jackson 08:44, 22 August 2014 (UTC)

This article seems like it is ready for prime time to me. It is well written, appropriately illustrated, and provides a solid overview of a technical topic in a way that I was able to understand without prior knowledge of the topic. The cluster of supplemental tabs each contain relevant information. Christine Bush 17:33, 21 August 2014 (UTC)
