Joanna,


Here is the process description Amy originally provided with detail
added about the pretreatment/conditioning steps and a reference for a
detailed report.  The web site announcing the "932" demo projects is
http://www.energy.gov/print/4827.htm.


Let me know if you need anything else.


Regards,


Kelly Ibsen
