The first fluid bed[edit]

Often, the first application of a technology in petrochem is not necessarily the first in all fields. Fluid beds were first commercialized for coal gasification (Winkler) in the 1920s. It was applied to metallurgical processes by Lurgi in the 1930s. Finally, in the 1940s Esso Research and Engineering came up with FCC. Dorrco came in with a lot of applications starting in the late 40s including calcination, sulfide roasting, sludge incineration and plastics drying. CFB coal combustors came on the scene in the 1980s. I would venture to say that most fluid beds in the world are not FCC units. Yes they are a very economically important application... but not the only one! BSMet94 20:13, 22 February 2007 (UTC)

Thanks for your comments. I have modified the history section of the article to reflect your information. I changed my previous statement to "one of the first US FBR's" and added a cited sentence stating Winkler as the first to develop the technology. I have not added content about the other individuals, as I am waiting until I find good sources for that information. If anyone can recommend some good sources that I might use, please let me know. Thanks. Hughesy127 22:43, 27 February 2007 (UTC)
Yeah, I'll check it out... I think there's some info in Kunii & Levenspiel mentioning Lurgi and Dorr-Oliver. In the 40s there was some chemical industry developments too, like acrylonitrile production. If I can find a reference, I'll add it.BSMet94 04:35, 28 February 2007 (UTC)
There is also use in biotechnology/ bioprocess engineering for various applications (including cell culture and beer brewing) which is not mentioned here. Maybe worthwhile adding it. Maybe I will do so if I find the time. LGreiner (talk) 14:25, 7 May 2013 (UTC)

Article overlaps[edit]

There is a note on the large number of overlaps in fluidization articles here: Talk:Fluidization#Article overlaps. If anyone has comment, let's have the conversation there. J JMesserly (talk) 20:27, 4 June 2012 (UTC)


The picture shows a special case which is commonly not used that much. Typically the fluid in the reactor and the passed fluid are the same. Gas is rather uncommon as the energy dissipates mainly in the fluid. Also, solids are typically retained and not taken out deliberately. Am I mistaken? LGreiner (talk) 14:28, 7 May 2013 (UTC)

Updated External Link[edit]

I have updated the external link to the ACS National Historic Chemical Landmarks program source. I am the program coordinator of the ACS-NHCL program.KLindblom (talk) 20:23, 21 February 2014 (UTC)
