Abstract: A process for producing urea ammonium nitrate (UAN) sodium bentonite suspension from hot urea solution, hot ammonium nitrate solution and dry solid sodium bentonite clay. The dry sodium bentonite clay is added directly to the hot urea solution without the use of expensive chemical dispersants. There is no need for intermediate processing steps involving the dispersion of clay in water, said water normally containing expensive chemical dispersants. After the sodium bentonite has been dispersed in the hot urea solution, then, and only then can the hot ammonium nitrate solution be added. Unexpectedly, the order of addition of the feed material to this process is highly critical. This economical and innovative production process is readily adaptable to existing commercial nitrogen fertilizer production plants and has solved many of the problems which have kept sodium bentonite from being widely used in the production of suspension fertilizers.
