Ammonium phosphates are produced by reactions of ammonia and phosphoric acid resulting in the formation of the mono-basic salt. A batch crystallizer in a pilot setup was utilized to produce pure MAP crystals using a fractional experimental design 25-2. The supersaturation level not only influences the growth rate but the crystal shape as well. %K Fertilizer (MAP) %K Crystallization To Larger Scale %K Fractional Experimental Design 25-2 %K Supersaturation %U http://article.sapub.org/10.5923.j.ijme.20120204.01.html
