Abstract:
     The present invention uses the fertilizers of ammonium nitrate and potassium chloride as raw materials and adopts the intermediate salt method to produce potassium nitrate. Let the circulatory mother liquid containing sodium nitrate act to the potassium chloride to obtain solid sodium chloride and potassium nitrate mother liquid. After dropping in temp., the product of crystalline potassium nitrate is obtained. Said mother liquid is separated and the sodium chloride and ammonium nitrate are put in to obtain the by-products ammonium chloride and circulating mother liquid containing sodium nitrate. Said method features over 90% of high yield, relative low energy consumption and easy operation and management.
