File talk:FRI Distillation Columns.jpg/Permission

The Fractionation Research, Inc. (FRI) website page at Publications has this statement:

The followings are the staff publications available in the public domain:

One of the staff publications listed just below that statement is Hydraulics of Kettle-Reboiler Circuit on Distillation Columns written by Tony Cai, Mike Resetarits, and Ahmad Shariat of Fractionation Research, Inc. ... and that publication contains this image.

On March 10, 2011, I telephoned Mike Resetarits at FRI and asked him to verify that the photo in that article was truly in the Public Domain and he verified that it was. Milton Beychok 21:24, 10 March 2011 (UTC)
