Kiln Phosphoric Acid (KPA) Process
EMSL Project ID
25416
Abstract
JDC, Inc. submitted a successful US Dept. of Agriculture phase I proposal (SBIR-2003-0022) to conduct a basic chemistry and engineering program to forward the KPA process, and carried out the work between June 1, 2004 and December 31, 2005. The laboratory research, which was principally performed at the Battelle Pacific Northwest National Labs (PNNL), reached the phase I objectives. A second USDA proposal was awarded June 1, 2006, focused on development work performed at vender testing labs and engineering firms, with the PNNL chemistry component involved analyzing products from vender tests and to finish some basic science issues identified in the first award. The second award has been extended to finish December 31, 2007. The process is at the advanced development stage shows commercial promise in producing a pure, high concentration phosphoric acid from phosphate ores and green petroleum coke for about one-half the cost of the presently used wet acid process. It also has major environmental advantages and uses green petroleum coke as the energy source which presently arises from the US oil refining activities, but is mostly used off shore as it presently has limited use in the US.
