COMPLEX NITROGEN-POTASSIUM FERTILIZER MANUFACTURE Russian patent published in 2004 - IPC

Abstract RU 2224717 C1

FIELD: mineral fertilizers. SUBSTANCE: crystalline potassium nitrate is dissolved in 56- 58% nitric acid to 2-16% potassium nitrate concentration and resulting solution is neutralized with gaseous ammonia to give mixed intermediate product containing ammonium and potassium nitrates. The latter is evaporated to melt and granulated by known technique. EFFECT: reduced power consumption in evaporation stage due to reduced amount of water introduced into process. 2 cl, 1 dwg, 2 ex
