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. [[User:David E. Volk|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. [[User:Milton Beychok|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. [[User:Milton Beychok|Milton Beychok]] 17:08, 23 February 2011 (UTC)

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)

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. Volk 14:22, 23 February 2011 (UTC)

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)
