This article came from Wikipedia
I was not the original creator of the Wikipedia article of the same name but, as a Wikipedian, I rewrote about 95% or more of it, added a flow diagram that I drew, and expanded the article.
I have uploaded exactly it as it now exists on Wikipedia, but will now proceed to clean it up, do some rewording and what ever else is needed to make it suitable for Citizendium. This may take me a few hours. - Milton Beychok 15:29, 7 February 2008 (CST)
- Milton, could undo the bold of "absorber" and "regenerator", and make them in italics instead for emphasis? I have nominated the article for approval, and will naturally support it if those two changes are made (note for the constables). David E. Volk 13:36, 28 April 2008 (CDT)
- David, I made those changes plus changing a few other places where I used bolding instead of italics. Thanks, Milton Beychok 14:18, 28 April 2008 (CDT)
One more item
Milton, could you add what the compounds formed are, ie [NH4]+SH-, or whatever? David E. Volk 13:38, 28 April 2008 (CDT)
- Dave, I have done so. Also added a reference to the classic book "Gas Purification" for those who may want to dig into the chemistry and the process more deeply. - Milton Beychok 15:43, 28 April 2008 (CDT)
Approval status
Just stopped by to check. There are about 5 edits that were made after the date on the ToApproval template. Do these need to be included? If so, don't forget to update the version on the template. See ya tonight (my time!) --D. Matt Innis 07:28, 12 May 2008 (CDT)
The article is ok as is, but
I would like to see the terms Acid gas removal and Gas sweetening lose their capital letters on the first word. David E. Volk 14:06, 12 May 2008 (CDT)
- Done. - Milton Beychok 17:08, 12 May 2008 (CDT)
APPROVED Version 1.0
Done. Good collaboration to get this one finished! --D. Matt Innis 23:11, 12 May 2008 (CDT)
Comments by Wim Van Wassenhove
I asked Wim Van Wassenhove to review this article and offer his comments, which he has done by email. Here are his comments (somewhat shortened):
You might want to add that:
(1) Typical amine solution contains around 30% of amine in water.
(2) The choice of the type of amine will affect the required circulation rate of amine, the energy consumption for the regeneration and selectivity.
(3) Amines absorb both H2S and CO2 and when it is only important to remove the H2S, the proper choice of amine concentration and composition will allow you to do that. Another possibility is the use of a so called activator such as Piperazine mixed with MDEA.
(4) In the "New amine-based materials for gas processing" section, I find the units "pounds of amine per ton of CO2 captured" a bit of a weird SI/Field unit hybrid.
Wim also suggested that I mention the use of amines for CO2 capture from power plant flue gas stacks.
In general, I agree with all his comments and I will revise the article in response to his suggestions just as soon as I can ... perhaps tomorrow. Thanks, Wim. Milton Beychok 03:21, 28 August 2009 (UTC)

Draft approval corrections
Milt, sorry for the delay in looking at this. Two things:
1) The following is not a real sentence, one or more words is missing at XXXXXX:
"The amine concentration in the absorbent solution is an important parameter in the design and operation of an amine gas treating process. Some typical concentrations for XXXXXXXXXXX (in weight percent) are"
2) Since the minimal or "about" wt percentages add up to 150% or more, does this mean only one amine is used at once, or possibly a few of them, as opposed to the each chemical being used all of the time? David E. Volk 01:48, 16 September 2009 (UTC)
